A printed box with an auto lock bottom is a stronger alternative to the printed cartons with an interlocking bottom. This custom carton features glued/taped flaps which pop-up and interlock with each other. Consequently, this box is ideal for holding heavy contents, while simultaneously promoting your company as branded packaging. 

Boxes With Auto Lock Description

The Auto-Lock Bottom box is a sturdy and reliable packaging solution that is designed to provide added strength and durability. This box is a stronger alternative to the interlocking box and is capable of holding heavier contents. The glued/taped flaps pop-up and interlock with each other, creating a secure and stable structure. 

It can also be easily collapsed to lay flat for convenient storage. This box is usually supplied assembled but collapsed ready to pop open! 

The Auto-Lock Bottom feature, also known as “Crash Lock” or “Crash Bottom,” adds to the box’s strength and stability, making it an ideal packaging solution for heavy or fragile items that require extra protection during transit.
