A base that locks itself into place

Auto lock bottom boxes pop into a firm, flat base in seconds, with no tape needed.

Auto Lock Bottom Boxes product range

An auto lock bottom box, sometimes called a crash lock or auto-bottom box, has a base with pre-glued panels that snap into a firm, flat shape the moment the box is opened out. There is no tape or extra folding needed, which makes it one of the fastest folding carton styles to assemble by hand.

Why It Is the Strongest Folding Carton Base

Because the bottom panels lock together rather than relying on a simple tuck flap, this style holds more weight than a standard tuck end box without extra support. It is a common choice for candles, bottled drinks, jars, and other heavier or bulkier products that need a base that will not give way.

Where This Style Is Used

You will find auto lock bottom boxes used across retail, cosmetics, food, and gifting, wherever a heavier item needs quick, reliable assembly. Many businesses pair the strong base with a simple tuck top, giving a box that is both quick to build and quick to open.

Materials

This style works well in both folding carton board, for a lighter retail box, and corrugated board, for anything that also needs to survive courier shipping. We will recommend the right material based on your product's weight and how it will travel.

Order Sizes We Support

Custom auto lock bottom boxes are available from around 50 to 100 units, so smaller businesses can access a strong, quick-assembly box without a bulk order. Unit prices fall as order volume grows for larger, ongoing supply.

Average Prices

As a general guide, auto lock bottom boxes typically cost between £0.50 and £1.80 per unit, depending on size, material, print colours and finish. These figures are a guide only, since pricing depends on your exact specification.

Sustainability

Recyclable corrugated and folding carton board are available, along with FSC-sourced options, so the strength of this base style does not need to cost the planet.
