Auto-Bottom Carton

An Auto-Bottom Carton is a type of carton structure whose bottom requires no tape or glue during forming; through pre-creased lines and special die-cut design, it automatically locks into a bottom with a single pull. It belongs to the category of instant-forming cartons and is commonly used in express delivery, e-commerce, food, and daily necessities packaging. Usage scenarios: suitable for automated or manual packaging lines that require fast packaging and improved efficiency, especially for large-volume shipments. Precautions: confirm whether the cardboard material and thickness meet load-bearing requirements; once an auto-bottom carton is formed, the bottom is not easy to disassemble and may be damaged during returns; dimensions must be designed precisely, otherwise the bottom-locking effect will be affected. Difference from a regular slotted container (RSC): RSC requires tape to seal the bottom, while an auto-bottom carton requires no additional bottom-sealing material, saving consumables and time; it is similar to a self-locking bottom carton, but an auto-bottom carton emphasizes 'automatic' forming, usually referring to a quick bottom-locking structure that requires no manual intervention. In foreign trade, the carton type, material, dimensions, and load-bearing capacity must be clearly specified in the contract to avoid disputes caused by differences in terminology understanding.
