Welcome to A New Era of Tiny Box
Welcome to the New Era of Tiny Box Company
We’ve been building something bigger.
After months of behind-the-scenes planning, designing, refining, we’re so excited to officially introduce a sharper look, a stronger voice, and a website designed to feel as premium, clear, and considered as the packaging we create.
Same team, same quality, same “details matter” energy, just a better, bolder, more beautiful experience from click to checkout.
Why We’ve Changed
Tiny Box Company has grown..into Big Box Co.
What started as beautiful everyday packaging has evolved into luxury custom projects, large-scale brand collaborations, sustainable innovations, and full packaging concepts for businesses of every size.
Our old look didn’t quite reflect where we are now, or where we’re headed.
So we asked ourselves:
How do we better showcase the quality and creativity we deliver?
How do we make it easier for customers to find exactly what they need?
How do we reflect the premium, sustainable, design-led packaging we’re known for?
The answer was a full refresh.
The New Brand Look: Cleaner, Elevated, Confident
You’ll notice things look a little different. Our new brand identity is:
Cleaner
More elevated
More refined
More aligned with the premium packaging we create
We’ve updated our visuals, refined our style, and created a clearer way to explore everything we offer, from everyday essentials to completely bespoke packaging solutions.
This rebrand reflects who we are today: a luxury, sustainable packaging partner trusted by growing brands, established businesses, and ambitious creatives alike.
The New Website: Faster, Smarter, More Inspiring
We’ve completely redesigned our website to make your journey smoother, simpler, and a lot more inspiring. Here’s what’s new:
Faster Performance: Because nobody likes waiting for packaging inspiration to load.
Easier Navigation: Clearer categories. Smarter filtering. A more intuitive way to browse, whether you know exactly what you need or you’re still exploring.
More Inspiration: More visuals, ideas, and support. Whether you’re designing your first product box or planning a full brand launch, we’re here to guide you.
Better Product Guidance: Not 100% sure what you need? We’ve designed the site to help point you in the right direction, guiding you towards products that suit your size, style, sustainability goals, and budget.
Our goal is simple: Make it easier to find what you’re looking for, and even easier to discover what you didn’t know you needed.
Introducing Tiny Box Company Pro
As part of our rebrand, we’re officially launching Tiny Box Company Pro; our dedicated offering for large-scale projects, high-value campaigns, PR agencies, and brands with bold ideas.
Think:

In short: a better experience.
A brand that reflects the premium packaging you’re investing in, a website that saves you time, more inspiration when you need ideas, and clearer pathways whether you’re a small business or a global brand.
What’s Not Changing
We may have had a glow-up, but the foundations remain exactly the same:
Same exceptional quality.
Same sustainable focus.
Same friendly, knowledgeable support team.
Same obsession with the details.
Because great packaging isn’t just about how it looks, it’s about how it feels, performs, protects, and represents your brand.

Labelling & Paperwork That Keep Parcels Moving
Who this guide is for
This guide is for UK small business owners and fulfilment leads shipping jewellery, candles and beauty products, boutique fashion accessories, and corporate gifts.
If you want a scan-first labelling SOP that keeps parcels moving smoothly (and customers smiling) you’re in the right place.
The result: fewer delays, fewer returns-to-sender, fewer surcharges, and faster dispatch thanks to clean, reliable scans.

Why parcels get delayed or returned
The five most common labelling mistakes
Most delivery issues come down to one of these:
Barcodes placed over seams or corners: Scanners struggle when codes bend or break across edges.
Glossy or curved surfaces under labels: Shine and curl = reflections and failed reads.
Low-contrast printing: Faded thermal heads or light print settings create weak bars scanners can’t lock onto.
Covered or duplicated barcodes: Tape across a code, or multiple visible labels, leaves scanners guessing.
Labels on the wrong face: Short sides or lid flaps often aren’t visible to conveyor scanners.
Paperwork that confuses scanners (and how to avoid it)
Loose return slips sliding over barcodes: Always secure paperwork in a pouch or integrate it into the label.
Documents Enclosed pouches stuck on top of labels: Place them next to the shipping label, never over it.
Address mismatches: Packing slip and shipping label should come from the same order state to avoid conflicting data.
Set up your label zones (once…and do it right)
Front-face placement, quiet zones, no seams
Reserve a flat front face at least 150 × 100 mm as your label zone.
Keep barcode quiet zones (the blank space around the code) clear of tape, text, or graphics.
Never let a barcode cross a seam, edge radius, or crash-lock join.
Think of this area as the barcode’s personal space, don’t crowd it.
Orientation for conveyors and hand scanners
Apply labels square to the panel, not on an angle.
Barcodes printed horizontally (bars left to right) scan fastest on conveyors.
For letterbox-friendly packs, place the label on the largest flat face (often the top).
Consistency beats clever every time.
Paperwork that travels cleanly
Documents Enclosed, integrated labels, or QR returns
Documents Enclosed pouch: Use when paper slips are required. Stick it adjacent to the label, never on top.
Integrated shipping + returns labels: Print in one pass. Customers peel the outbound label and keep the returns section, simple and tidy.
QR returns: No paper inside the box. Include a short URL or QR on the packing slip instead.
Where to place pouches (without blocking scans)
Place pouches on the same face as the shipping label.
Leave a minimum 20 mm gap.
Keep pouch edges clear of barcode quiet zones.
Smooth out wrinkles and bubbles before dispatch.
Flat beats floppy. Every time.
The 60-second bench SOP (scan-first)
Wipe → label → press → scan → pouch → final check
Wipe the label face with a lint-free cloth
Apply label within the 150 × 100 mm zone, no seams or corners
Press firmly with fingers, then a small roller for even adhesion
Scan test once:
If it fails: reprint and replace
Never stack labels
Add pouch (if needed) beside the label and insert paperwork
Final check: remove any old labels
Optional: photograph the label face for proof
One clean label beats three “just in case” ones.
Photo proofing and exception handling
Photograph high-value or exception parcels and store images with the order ID.
For re-boxed returns, fully void old labels. Marker pen alone isn’t enough.
If a barcode can still be seen, a scanner will try to read it.
Train, audit, and improve (without slowing dispatch)
First-10 audits, fault boards, and weekly tallies
First-10 audit each shift: Check label zone, seams, scan test, and pouch placement. Team lead signs off.
Fault board with real photos: Examples like “barcode over seam,” “tape on code,” “pouch on label.”
Weekly tally of scan failures and RTS: Add a one-line fix next to each issue so it doesn’t repeat.
Seasonal tweaks for gift sets and busy periods
Pre-print integrated labels for common SKUs.
Add label-zone photos at the bench for new cartons.
For glossy gift wraps, use matte labels or apply to a paper panel area.
Peak season is no time for scanner surprises.

FAQs
Where should a shipping label go for best scans?
On a flat front face within a 150 × 100 mm zone, away from seams and corners, with barcode quiet zones clear.
How big should barcodes be, and what are quiet zones?
Follow your carrier’s specs. Quiet zones are the blank margins around the code. Keep them free of tape and graphics so scanners can lock on quickly.
Can I place a Documents Enclosed pouch near the label?
Yes. Place it beside the label on the same face, leaving at least 20 mm and keeping clear of the barcode area.
What’s the best way to include returns paperwork?
Integrated labels or a pouch work well. QR returns remove paper altogether.
Do I need integrated labels, or is a QR return enough?
Either works. Integrated labels speed up repacking; QR returns reduce paper. Choose based on your return rate and customers.
How do I train packers to label consistently?
Use the 60-second SOP, a photo fault poster, and first-10 audits.
What’s the quickest dispatch check to catch issues?
Check seams and edges, scan once, confirm pouch offset, and ensure only one visible shipping label.

Returns-Ready Packaging That Meets Courier Rules
Who this guide is for
This guide is for owner-managers and fulfilment leads at UK independents and SMEs shipping jewellery, candles and beauty products, boutique fashion accessories, and corporate gifts.
You need postal packaging boxes that are genuinely returns-ready:
Easy to relabel
Simple for customers to reseal
Sized to stay inside typical UK postal bands
Outcome: fewer surcharges and damages, quicker return turnarounds, and happier customers who don’t need to wrestle a box back into shape.

What “returns-ready” really means (for you and your courier)
The three basics: integrity, readability, right-sizing
Integrity: The box survives two journeys. Panels stay square, seals hold, and inserts keep the product where it should be, no rattling souvenirs.
Readability: Labels and barcodes sit flat on clean panels. Nothing crosses seams, corners, or tape lines that scanners hate.
Right-sizing: Once re-packed, the return still fits your target letterbox-friendly or small-parcel-style band, no surprise fees on the way home.
Why double-seal mailers save time (and money)
A double-seal does exactly what it says on the box:
Strip 1 seals the outbound order
Strip 2 is there for the return
No tape hunting. No loose flaps. No “I tried my best” customer reseals.
Add a tamper-evident tail and disputes get easier too, it’s obvious where the box was opened and how it should be closed again.
Pick the right carton for both outbound and inbound
Letterbox-friendly vs Small-Parcel mailers
PIP / letterbox-friendly postal boxes (UK): Slim formats for jewellery cards, pouches, scarves, and neatly folded tees. Pair with board backers and thin risers to keep things flat and protected.
Small-parcel-style mailer cartons: A little more height for candles, small bottles, and gift sets. Look for strong edge crush and clean, flat label panels.

Read our blog →
Crash-lock or regular mailer; when to use each
Crash-lock bases (FEFCO 0711 / 0713 styles): Fastest to erect (your pack bench will thank you). Add a peel-and-seal plus a second strip on the flap to make them returns-ready.
Self-locking mailers (FEFCO 0427 / 0426 styles): Tidy corners and great presentation. Specify a double-seal tape or resealable strip from the start.
Set up seals, labels, and inserts properly
Double-seal placement (and how customers know what to do)
Strip 1 sits on the flap edge for outbound shipping
Strip 2 sits 10–15 mm behind it, clearly printed “Reseal Here”
Add a small printed arrow on the receiving panel to show where to press
For heavier items, consider short side-tab seals customers can replace with the provided tear-tapes.
Labels, pouches, and barcode do’s & don’ts
Do:
Reserve a clean label zone at least 150 × 100 mm
Keep barcodes flat, smooth, and away from corners
Use “Documents Enclosed” or return-label pouches on the flattest face
Don’t:
Seal over labels
Run labels across openings or tape seams
Put barcodes on glossy or highly textured wraps
If the scanner can’t read it, neither can your courier’s patience.
Foam-free inserts that still protect on the way back
Use card or moulded pulp collars, U-cards, and platforms to control movement
For candles and bottles, add edge or corner pads instead of deep void-fill
Keep overall height down so the return stays inside band
Less bulk, less bounce, less drama.
Build a simple returns kit (customers will actually use)
Label options, instructions, and reseal cues:
Include either a pre-printed return label or a QR/URL that generates one
Say which it is on the packing slip, don’t make customers guess
Print a short instruction line on the flap: “Peel blue liner to reseal. Remove old label. Apply new label here.”
Add a small pull tab so the second liner lifts cleanly (glove-friendly = bonus points)
Help customers re-pack without adding bulk
Print simple icons inside the lid showing the fold sequence and insert order
Add a mini checklist: remove old label → re-seat insert → reseal strip 2 → apply new label
Think IKEA clarity, not instruction-manual despair.
Train your team and close the loop
Returns bench card (A6, taped to the table):
Confirm band target (letterbox-style or small-parcel-style)
Pick carton with double-seal; check strip 2 is present
Add card/pulp insert (foam only if essential)
Place label on clean panel; pouch if needed
Pack in return label or QR + brief instructions
Seal strip 1
Photograph top and label side for records
First-week audit:
Log returns with surcharges or damage
Tag the cause: over-thickness, unreadable barcode, weak seal, loose item
Update SOP notes and share photos of “good returns” in team chat
Seasonal tweaks:
Gift sets and promos change the game; add temporary rows to your matrix, dry-fit early, and retire them once the season ends
Mini matrix: common SKUs → returns-ready picks
Keep this printed at the pick face, with a photo of the label zone for each carton.
Ring box + pouch: Letterbox-style → PIP double-seal + 2 mm riser & board backer
Candle Ø78 × 90: Small-parcel-style → Mailer-S double-seal + collar, 5 mm platform, corner pads
Scarf (folded): Letterbox-style → PIP double-seal + 1 mm board backer
Serum 30 ml ×2: Small-parcel-style → Crash-lock-S double-seal + U-cards and sleeve
Short codes. Clear photos. Zero guesswork.

FAQs
What makes packaging “returns-ready” for UK couriers?
Clean label zones, durable (ideally double) seals, right-sized cartons, and inserts that stabilise products on the return trip.
Do I really need double-seal strips?
For most postal mailers, yes. Two peel-and-seals on the flap mean easy returns and fewer tape-related mishaps.
Where should labels and document pouches go?
On a flat panel around 150 × 100 mm, away from seams and corners, with barcodes fully visible.
Which boxes work best for letterbox vs Small-Parcel returns?
Slim PIP postal boxes for jewellery and soft goods; mailer cartons for candles and small bottles—both with double-seal options.
Which inserts protect without adding bulk?
Card and moulded pulp collars, U-cards, platforms, and edge pads. Foam only when absolutely necessary.
What should go inside a returns pack-in?
A label or QR/URL, one-line instructions on the flap, and a clear “reseal here” cue.
How do I train packers and spot issues quickly?
Use the bench card, run a one-week audit, and add photo examples of winning packs to your SOP.

Avoid Oversize Charges with Smart Carton Picks
Who this guide is for
This guide is for owner-managers and fulfilment leads at UK independents and SMEs shipping jewellery, candles and beauty products, boutique fashion accessories, and corporate gifts.
You want:
Fewer surprise carrier surcharges
Faster, smoother packing at the bench
Packaging that still feels premium when it lands on the doormat
Outcome: a UK-focused, carton-pick playbook that helps you stay inside size bands, cut dimensional (DIM) weight, and speed up packing, without adding waste or dulling the unboxing experience.

Why you’re getting hit with oversize charges
DIM vs actual weight (plain English)
There are two ways carriers look at your parcel:
Actual weight: What the box physically weighs on the scale.
Dimensional (or volumetric) weight: A “theoretical” weight based on how much space the parcel takes up:
DIM weight (kg) = (Length × Width × Height) ÷ divisor
(Measurements in cm. The divisor depends on the carrier and service.)
Carriers charge whichever is higher: actual weight or DIM weight.
That’s why big, light boxes are the usual troublemakers. They don’t weigh much, but they hog space in a van. And space, as carriers see it, isn’t free.
Think in size bands (not carrier brands)
Instead of memorising every carrier’s rules, think in size bands. Most UK services follow similar ideas:
Letterbox-friendly / “PIP Large Letter-style”: Slim, through-the-door formats with tight thickness limits.
Small-parcel-style: A bit more breathing room, great for candles, small bottles, and boxed sets.
Medium-parcel-style: Looser limits, but DIM weight can creep up quickly.
Treat published limits as guardrails, not gospel. Always double-check live specs with your carrier, especially ahead of peak.

Carton families that hit the bands
Picking the right box shape (before filling it with hope and void-fill)
PIP / letterbox-friendly postal boxes (UK): Designed to stay slim. Ideal for jewellery cards, flat accessories, scarves, and lightweight refills.
Mailer cartons (FEFCO 0427 / 0426 styles): Self-locking, strong edges, quick to build. A solid go-to for Small-parcel-style bands.
Crash-lock base cartons (FEFCO 0713 / 0711): Fastest to erect (your packers will love them). Just watch the base glue, it can add sneaky millimetres to height.
Standard RSCs (FEFCO 0201): Cheapest per unit, but rarely the best choice when size bands matter.
Inserts that protect without adding bulk
Choose card or moulded pulp platforms over foam to save 2–5 mm of thickness.
Use edge or corner buffers (L-profiles or folded card) instead of loose void-fill that balloons the box.
For small bottles, diagonal nesting can shave enough length or width to drop a whole size band.
Less air. More intent. Everyone wins.
Build a carton-pick matrix your team can actually use
Map your top 20 SKUs to 1–2 cartons, plus inserts and a fallback. Keep it simple. This should be readable at a glance.
What to include:
SKU / set name
Packed product size (L × W × H in mm)
Target size band
Primary carton + insert
Max units per carton
Fallback carton
Notes (orientation, padding tweaks)
Example (shortened):
Ring box: Letterbox-style → PIP box + 2 mm card riser
Candle (78 mm): Small-parcel-style → Mailer + collar and platform
Serum bottles: Crash-lock + U-card insert (cross-nest if packing two)
Tip: Keep carton codes short and visible at the pick face, and always show:
Primary option
Fallback
Max units per carton
Your future self (and your packers) will thank you.
Orientation tricks that save space
Sometimes you don’t need a new box, just a new angle.
Rotate products to reduce the problem dimension (often thickness).
Stack bottle caps opposing each other to lower overall height.
Bundle flat items (cards, pouches) with a belly band instead of loose fill.
It’s like Tetris, but with fewer beeps and more postage savings.
Quick DIM wins you can do at the bench
If thickness breaks the letterbox band: Swap foam → card/pulp and remove unnecessary tissue layers.
If length is the issue: Rotate the product or insert 90° and dry-fit again.
If DIM weight is high: Try the next smaller mailer that still protects the edges.
Tape, seals, and sneaky millimetres
Use H-tape only when needed. Over-taping adds bulk and weight.
A smaller box + edge protection beats a big box stuffed with fill.
Final check: panels flush, no bulge, labels inside safe zones.
If it looks stressed, the carrier will be too.
Train once, save daily
Bench card (A6, taped to the table):
Measure packed product → confirm target band
Pick Carton A (use fallback if needed)
Add card/pulp insert to control movement
Dry fit → check dimensions
Seal with minimal tape
Label flat
Spot-check 1 in 10
First-week audit:
Log any surcharges and note the cause
Update matrix notes for repeat offenders
Share 3 photos of “perfect packs” with the team
Seasonal sanity check:
Add temporary rows for gift sets and promos
Test bundles early
Remove retired SKUs to keep the matrix tidy
A simple DIM calculator you can run in seconds
Measure packed L × W × H in cm
Multiply to get volume
Divide by your service’s divisor (often 4000–6000)
Compare DIM weight to actual weight. The higher one is billed
Example:
32 × 22 × 12 cm = 8,448 cm³
÷ 5,000 = 1.69 kg DIM
Shave 2 cm off height:
32 × 22 × 10 = 7,040 cm³ → 1.41 kg DIM
Those tiny height reductions? They’re often the biggest money-savers.
Thickness: the make-or-break millimetres
Mark 25 mm and 35 mm clearly on your bench ruler

FAQs
What is dimensional (volumetric) weight, and why does it matter?
It’s a charge based on parcel volume. If it’s higher than actual weight, that’s what you pay.
What are PIP or letterbox-friendly boxes best for?
Jewellery cards, scarves, pouches, refills. Anything slim enough to pass thickness limits.
How do I keep parcels inside Large Letter or Small Parcel-style bands?
Measure the packed item. Control thickness first, then length and width.
Which cartons work best for candles or jewellery?
Candles: tight mailer with a card collar and platform. Jewellery: PIP postal box with a thin riser and board backer.
What inserts protect without adding bulk?
Card and moulded pulp platforms, collars, U-cards, and edge pads.
What’s the fastest way to fix oversize fees?
Track surcharges for one week, tag the cause, update your matrix, and share a photo of the winning pack.

Bespoke Inserts That Protect & Present
Bespoke inserts that protect and present
If you’re a UK independent or small business, whether you’re a maker, jeweller, beauty brand, or corporate gifter, this guide is for you. It’s a practical, no-nonsense walkthrough of how to choose and specify inserts that keep products safe in transit and look spot-on when the box is opened.
We’ll cover foam and foam-free inserts, sizing and fit, colour and finish, lid pressure, quick bench tests, and simple quality checks. No industry waffle. Just what works, so your packaging pulls its weight without dropping the ball (or the candle).

What a great insert must do
Protect the product, present it beautifully, and speed things up
A well-designed insert should:
Hold the product steady: A snug but forgiving fit that stops movement without forcing things in.
Create space where it matters: Keep items away from hard edges, and from each other.
Absorb knocks and drops: Cushioning that helps products arrive in one piece.
Prevent scuffs and scratches: No rub marks, dye transfer, or mystery micro-scratches.
Show the product at its best: Think finger-lifts, pull tabs, and clean, symmetrical layouts.
Make packing quicker: Clear orientation and a true “drop-it-in” fit, no wrestling required.
Common insert problems (and easy fixes)
Rattles when shaken: Cavity too loose → tighten the fit or add gentle “kiss-fit” ribs.
Scuff marks on the product: Sharp corners or rough edges → add small radii or a liner.
Colour transfer: Dark foam touching light products → use a white facing and run a 24-hour contact test.
Crushed or tight lids: Insert too tall → reduce the height or add a seating ledge so the lid closes cleanly.
Foam vs foam-free inserts: which should you choose?
We’re materials-agnostic. The right choice depends on your product, your values, your budget, and how quickly you need to move.
Foam inserts at a glance (EPE, EVA, PU)
Foam type
Feel
How it’s cut
Look in the box
Good to know
EPE (expanded polyethylene)
Firm, springy
Die-cut, waterjet
Clean, matt
Lightweight and protective. Recycling options vary—check local guidance.
EVA (ethylene-vinyl acetate)
Dense, precise
Die-cut, laser, waterjet
Crisp, premium
Ideal for custom foam inserts for boxes where accuracy matters (jewellery sets, kits).
PU (polyurethane)
Soft, sponge-like
Die-cut
Plush, cushioned
Popular for foam inserts for jewellery boxes. Use a facing sheet for high-polish metals.
Finish tips: Black foam looks luxurious but can show dust (especially in product photos). White foam looks clean but shows handling marks more easily. For photography-friendly results, a white foam insert for a jewellery box, or a coloured card liner on top of black foam, often hits the sweet spot.
Odour and rub checks: Ask for low-odour foam grades, always test with 24-hour contact on a spare product, and include disposal guidance where possible.
Getting the geometry right
Clearances, radii, finger-lifts, and multi-item layouts
Cavity clearance (solid items): Aim for 0.5–1.0 mm all round. For fragile glass (candles, bottles), allow 1–2 mm plus a soft liner.
Depth: Products should sit 2–3 mm below the top surface to avoid lid contact.
Radii: Add 1–2 mm internal curves to protect finishes and make insertion easier.
Finger-lifts: Use 10–12 mm wide notches or ribbon pulls, with rounded edges.
Multi-item sets: Leave 6–10 mm between items so they don’t knock together.
Shared bases: A single base with swap-out top pieces works well for seasonal or changing ranges.
Lid pressure and the “no-rattle” test
Target: A silent shake at arm’s length. If it rattles, add a low-tack top pad or increase height by 0.5–1.0 mm.
Lid fit: Inserts should support the product, not fight the lid. The lid should close flush, without bowing or force.

Sampling, testing, and sign-off
Start with CAD drawings for layout and dimensions.
Request a PPS (pre-production sample) using your actual product.
Drop test: 3 drops each on base, edge, and corner from 30–60 cm. No cracks, no crushed corners, no movement beyond 1 mm.
Shake test: 30 seconds of firm shaking. Listen for rattle; check for new marks.
Rub test: 24-hour contact under 250–500 g weight on the most delicate surface.
Extraction feel: One-hand lift, no tug-of-war.
Colour, liners, and photography checks
Test black vs white vs coloured liners under daylight and warm lighting.
Shoot a quick product photo. Dust, reflections, and colour cast show up fast on camera.
Cost, MOQs, and lead times (the practical bit)
Where each option usually wins:
Foam (EPE/EVA/PU): Fastest route to custom foam inserts for boxes, great accuracy, strong option for small to mid-sized runs.
Pulp or card: Strong sustainability message, efficient for larger volumes once tooling is spread out.
A simple savings example:
Current damage rate: 3% on a £30 product = £0.90 lost per unit
Improved insert adds £0.35 per unit
Damage drops to 0.5% = £0.15 loss per unit
Net saving: £0.40 per unit, plus fewer returns, happier customers, and better reviews. (Nice little win, neatly boxed.)
Handover and quality checks
What to include in your spec pack:
Annotated drawings (dimensions, depths, radii, finger-lifts)
Material details (foam type/density or card/pulp spec)
Colour, liner, and facing notes
Tolerances (guide: cavity ±0.5 mm, overall ±1.0 mm)
Required tests and pass/fail criteria
Goods-in checks:
Visual: clean cuts, no crumbly edges, colour matches approval
Dimensional: spot-check 1 in 20 on key sizes
Functional: quick shake test, there should be no noise

FAQs
What is the foam in boxes called, and which type is best?
Common options are EPE, EVA, and PU. EVA gives the sharpest, most precise cavities for custom foam inserts for boxes; PU feels soft and plush; EPE is light and protective. The best choice depends on your product and finish.
When should I avoid foam altogether?
If mono-material recycling or a strong eco message is a priority, moulded pulp or card inserts are excellent alternatives.
What’s best for precision kits vs gift boxes?
High-density EVA suits technical, tool-style fits. For foam inserts for gift boxes and jewellery, PU or fine-cell EVA with a facing sheet looks premium.
How thick should inserts be for fragile items like candle glass?
Start with 10–20 mm of cushioning, 1–2 mm side clearance, and a soft facing. Increase thickness for heavier items and validate with drop tests.
How do I make products easy to remove?
Use 10–12 mm finger-lifts and 1–2 mm internal radii. Small details—big difference.
How can I test inserts quickly before committing?
Run three basics: drop test (30–60 cm), shake test (30 seconds), and a 24-hour rub test. Only sign off once all pass.
Will black foam cause dust or dye transfer?
It can. Use white facings on light or polished products, lint-roll before photography, and always run a rub test.
