Snap lock bottom boxes, also called 1 2 3 bottom or crash lock boxes, are folding cartons with a pre glued bottom that snaps into a locked base when you square the box, built to hold heavier products without the bottom giving way. We make them with no minimum order quantity, so you can order 100 to test or hundreds of thousands for production, at a per box price we will quote against your current supplier.
The snap lock bottom is an engineered base where the flaps interlock as the box is opened, so it holds more weight than a tuck bottom without needing tape or glue at your end. We build them in 18pt to 24pt SBS or kraft, sized to your product, with a tuck or seal end top, and options for a window and coatings. This is the base you want for heavier retail products, glass bottles, and anything where a tuck bottom might pop open under load, and it still folds flat for shipping.
Snap lock bottoms save labor and prevent failures, because the base locks in one motion at your packing station and holds the weight without extra assembly. We help you decide when the snap lock earns its slightly higher cost over a tuck bottom based on your product weight. Send your product dimensions and weight and we will build a dieline and free proof. If you have a competing quote, send it and we will try to beat it.
