FAQs

What is a crash lock box?

Crash lock boxes – also known as self-locking cardboard boxes – are a type of packaging that requires minimal assembly. The base of the carton simply folds out and locks into place in a single action, meaning there is no need for glueing or taping.

How does a crash lock box work?

A crash lock base works by folding out as the person assembling the box pulls the corners of the box apart. As the sides of the base come together, the profile of their sides locks together, forming a solid base.

What materials are crash lock boxes made from?

Crash lock boxes can be manufactured from both single-wall and double-wall corrugated cardboard. Similar designs are available in Correx® plastic. However, GWP determines the best type of material to use based on your specific requirements, considering product size, weight and intended use. Doing this ensures you receive the most cost-effective option that doesn’t compromise performance.

Are crash lock boxes available in custom sizes?

All of the crash lock boxes that GWP manufactures are bespoke to your requirements. Not only does this allow for optimum performance, but it also minimises wasted material (and cost). It can also help reduce shipping costs, as you are not paying to ship empty space or excessive void fill.

Can you print crash lock boxes?

Crash lock boxes can have printing applied during the manufacturing process. Print can include everything from simple, single-colour logos to bright, striking graphics. It can also be helpful to include supplementary information such as handling instructions and recycling guidance.
