When brand recognition is not a strength, the appearance of the package becomes an even more critical factor in attracting the consumer. The techniques of modern boxmaking has thus become both an art and a science that often determines the success of a product in the ever-competitive merchandising arena of retail stores. The product is placed in the tube and the ends of the tube are sealed by flaps that fold over. The ends of the box have flaps that fold over and are glued closed. This type of box is often used with equipment that automatically inserts the product and seals the ends with a thermal glue or other fast-setting adhesive.
Slit lock One end of the box has a flap that folds over and folds down into the other end.
Rather, the flap stays reasonably secure through the pressure between the sides of the carton and the flap that tucks in front. This type of lock is usually used on the top of cartons only, where there is no weight applied that might loosten the closure. Bellows Rather than use rectangular flaps, this type of closure is achieved by precisely scoring an extention from the tube and collapsing it along its score lines. Usually, a tounge is used to secure the end in place. This type of closure is used only for the underside of a carton.
