Crash Lock Boxes Explained: Sizes CL-A to CL-K and How They Work

Crash lock boxes are cardboard boxes with a pre-glued base that folds in and locks as you open the flat box, so you never tape the bottom. Pack Solution stocks ten sizes, from CL-A (100 x 100 x 70mm) to CL-K (426 x 300 x 300mm), sold per box with a minimum of 5 per size. They suit anyone who builds a lot of boxes in a day. A die cut box or a standard taped box is often the better choice for low volumes or heavy goods.
