“A3” is the product size category. The actual listed carton
dimensions are 440 × 316 × 180mm, not the 297 × 420mm dimensions
of an A3 sheet of paper.
Before ordering for a closely fitted product, confirm whether
the published dimensions refer to internal or external box
dimensions and allow room for any protective packing material.

structure for general packaging and storage.
Approximately 6mm

millimetres.
Brown Kraft Finish
Supplied as a plain brown carton without custom logo or
full-colour printing under this product.
No maximum load, edge-crush, burst-strength or stacking-load
rating is currently published for this product. Select the box
according to the actual item weight, packing method and transport
conditions rather than assuming a specific heavy-load capacity.
Check Your Item Size Before Ordering
Measure the Product
Check the item's length, width and height rather than
relying only on the “A3” product name.
Allow Packing Clearance
Leave enough room for protective wrap, cushioning or
other packing material where required.
Avoid Overfilling
The closing flaps should meet naturally without forcing
or deforming the carton.
If your item dimensions are very close to 440 × 316 × 180mm,
confirm the usable internal dimensions before purchasing.
Suitable Applications
A3 Document StorageGeneral Product PackingE-Commerce PackingOffice RelocationHouse MovingWarehouse OrganisationRetail Stock StorageGeneral Transportation
Suitability depends on the item's dimensions, weight, fragility
and the level of cushioning used inside the carton.
Packing & Handling Tips
Seal Securely
Use suitable carton tape across the closing flaps before
transportation.
Protect Fragile Items
Add suitable cushioning where the packed item requires
impact protection.
Keep the Carton Dry
Corrugated board is not a waterproof packaging material.
Protect it from rain and prolonged moisture.
Distribute Weight
Position contents evenly rather than concentrating all
weight against one edge or corner.
Do Not Overload
Stop using the carton if the board, seams or corners show
excessive deformation.
Label When Needed
Identify fragile, storage or destination information on
the outer carton where appropriate.

printed packaging item. Stock availability may change, so check
the current product availability when the cartons are required
for a fixed packing or moving date.
This product does not include custom logo printing, artwork
design or personalised box dimensions. For custom printed
