Lock-Bottom Box

Lock-Bottom Box is a corrugated cardboard box with a tuck-in lock structure at the bottom, which can be fixed by the interlocking of the cardboard's own slots and tabs without tape or adhesive. It is commonly used for small and medium-sized packaging of electronic products, daily necessities, gifts, etc. In foreign trade, this term is used to describe the packaging method, affecting transportation safety, cost, and environmental compliance. Usage scenarios include: customers requiring eco-friendly adhesive-free packaging, needing quick assembly, or flat transportation to save storage space. Precautions: specify cardboard material (e.g., K=K, A=B), grammage, dimensions, and load-bearing capacity; lock-bottom boxes are generally not suitable for overweight or fragile items, and repeated opening and closing may cause loosening. Compared with 'Lid-Bottom Box', lock-bottom box has no separate lid and is integrally formed; similar to 'Snap-Lock Bottom', but snap-lock bottom emphasizes self-locking at the bottom, while lock-bottom box is broader. In foreign trade contracts, 'Lock-Bottom Box' and specific specifications should be stated to avoid confusion with 'Folding Carton'.
