Custom Flat Pack Boxes UK – PackagingX

Flat Pack Boxes for Easy Storage and Efficient Shipping

Flat pack boxes are delivered unassembled and fold into shape when needed — no glue, no staples, just pre-scored fold lines that click into place in seconds. For businesses that need to store large quantities of packaging without giving up half a warehouse to pre-built boxes, flat pack is the practical choice. They are widely used across retail, e-commerce, food, cosmetics, and subscription box businesses throughout the UK.

PackagingX manufactures custom flat pack boxes in any size, board weight, and print finish for businesses of all sizes.

Customisation Options

• Size — made to your exact product dimensions
• Material — cardboard, kraft board, or corrugated board for heavier products
• Board weight — light retail grades up to heavy-duty corrugated
• Print — full colour CMYK or PMS on all external panels
• Finish — matte, gloss, soft-touch lamination, spot UV, foil stamping
• Branding — logo, product information, and artwork across all panels

Space-Saving Flat Pack Packaging That Ships Efficiently

Because flat pack boxes arrive compressed and unassembled, you can store significantly more units in the same space compared to pre-built boxes. This also reduces shipping costs when ordering in bulk, as flat stacked boxes take up far less volume in transit. For e-commerce and retail businesses managing stock across multiple locations, that efficiency adds up quickly.

Sustainable Flat Pack Box Options

All our flat pack boxes are made from recyclable materials. Kraft board and FSC-certified cardboard are available as standard options. Water-based inks are used where possible, keeping the finished box fully recyclable at end of use.
