Auto Lock Bottom Boxes | Custom Folding Cartons

Custom Auto-Lock Bottom Boxes for Wholesale Packaging

Auto-lock bottom boxes, also called crash-lock bottom boxes, are folding cartons with pre-glued bottom panels that automatically lock when the flat carton is erected. This structure helps packers assemble boxes quickly without a separate gluing step, while the cartons ship flat for efficient storage and transport. Custom paperboard sizes, CMYK printing, finishes, and an optional tear strip suit cosmetics, skincare, e-commerce, candles, and other retail products.

Crash-Lock Bottom Box Structure & Applications

The crash-lock bottom is formed by folded and pre-glued panels that lock into place as the carton is opened. The result is a stable base for retail packing, with flat shipping and storage before use. Specify the product dimensions, paperboard weight, print coverage, finish, and whether a tear strip is needed so the structure can be matched to the application.
