Choose different mechanisms between auto lock or tuck style to seal and secure packaging. Auto lock involves tabs or flaps on the packaging that automatically lock into place when the carton is folded, without the need for additional adhesive. It can also be stronger for products that are heavier. Tuck style involves tucking the flaps of the carton into designated slots or openings to secure the packaging. This method requires manual folding and tucking, ideal for products that need to be resealable or accessed multiple times.
