What’s a flat-pack box?

A flat-pack box is packaging that arrives flat and easily folds into shape. Unlike rigid boxes, flat-pack boxes save storage space and shipping costs by being compact until needed. 

Discover our range of rigid two-piece postal boxes here, also ideal for premium gift packaging.

Key benefits:

Space-saving: Store flat and assemble only when needed, ideal for businesses managing limited storage space. 

Easy assembly: Quick-fold designs with self-locking tabs - no tape or glue required.

Durable protection: Strong corrugated cardboard ensures safe shipping for delicate items. 

Customisable: Easily branded with logos or custom designs, enhancing your customer's unboxing experience.

Common uses:

E-commerce shipping: Secure, professional packaging for online retailers.

Gifts & subscriptions: Durable and stylish for a memorable unboxing experience. 

Storage & organisation: Convenient for storing documents, books, and supplies at home or in the office.
