Custom Full Flap Auto Bottom Boxes

Board Choices for Heavier Goods

For moderate weights, a thick folding boxboard gives sharp print and enough strength. For heavier products, micro-flute corrugated board, where a thin fluted layer sits between two liners, adds significant crush resistance while still taking good quality print.

White-lined board prints bright colours and photographs well, ideal for appliances and retail products. Kraft board gives a rugged, natural look that suits hardware, workshop and outdoor products.

Tell us the product weight and how many cartons will be stacked in storage. Those two figures decide the board more than anything else.

Humidity is worth mentioning if your goods are stored in an unheated warehouse or garden centre. Damp air softens board over time, and a slightly heavier grade or a protective varnish keeps the carton rigid through months on a shelf.

Sizing and Inserts

Measure the product at its widest, deepest and tallest points, including any handles, plugs or protruding parts. We then add a small clearance so the product slides in without forcing, but not so much that it moves around.

Loose fit is the enemy of heavy products, because a heavy item sliding inside a box will eventually punch through a wall. Card inserts, partitions or folded supports hold the product in place and spread its weight. For bottles and jars, a cell divider keeps each one separate.

If you pack several products of the same family, one box with adjustable inserts can sometimes cover them all.

Products with sharp corners or edges, such as metal brackets or boxed blades, benefit from a folded card collar at each end. It keeps points away from the walls and stops them wearing a hole during transport.

Printing a Box That Sells on the Shelf

Full flap auto bottom boxes are usually retail packaging, so they need to look good as well as be strong. Full colour printing on every panel lets you show the product, its features and specifications. A clear front panel with a large product image and name works best for shelf impact.

Side panels are often used for specifications, contents lists and instructions. The base can carry the barcode, compliance information and manufacturer details.

Because the top flaps overlap, the visible top panel is the outer flap. We make sure your design is placed on that flap so it looks right when the box is closed.

A window on the front panel is possible on this style, though it reduces strength slightly. For heavy goods, keep the window modest and away from the corners, or show the product with a large printed photograph instead.

Retailers that sell online as well as in store sometimes ship the printed carton inside a plain outer box. In that case a simpler outside print can save cost, with the full design reserved for the faces that matter on a shelf.

Packing Faster

The auto bottom is designed for speed. Staff open the flat carton, the base locks itself, the product goes in and the top flaps fold over. For high volume packing, that is much quicker than taping or tucking a base on every box.

Top flaps can be closed with a tuck, a lock tab or a strip of tape depending on how secure the box needs to be. A tear strip can also be built into the top for easy opening by the customer.

Packing benches benefit from a stack of opened cartons ready to go. Because each box springs into shape with its base locked, staff can prepare a batch at the start of a shift and fill them steadily without stopping to assemble each one. Square products such as tins often use the same base in our cube boxes with a crash-lock base.

Stack Five Packed Cartons for Two Days

The test that matters for this carton is stacking, so pack a few products in plain samples of the suggested board and leave them five high for a couple of days. If the bottom carton bows or a corner softens, the board or the insert changes before the print run. Give us the product weight and the stacking height in your warehouse, as those two figures choose between thick boxboard and micro-flute; add the dimensions with handles and plugs included, and say if the stock sits somewhere damp.

Send the dimensions, weight, stacking height and artwork, and a custom quote comes back by email within one working day, with simple cartons from £0.25 and low minimums quoted per job. The free proof shows the flat carton with the flap overlap marked. Production takes 4–7 working days after approval and tracked delivery to UK mainland addresses is free, taking 2–3 working days. Damaged or misprinted cartons reported within 10 days are reprinted or refunded. Products that ship in their own carton by courier often move up to double wall tuck top boxes.
