It is understood that in order to cope with increasingly fierce competition, food companies have always tried every means to find ways to surprise, through the continuous innovation of the structure of the carton to enhance corporate image, promotional products, such as window boxes, with handle tray, shaped Boxes, etc., and the use of tear-off thread at the opening of the carton is becoming more and more popular. The design of easy-to-remove openings is increasingly used in the application of cartons. The advantages of this design are obvious: If it is convenient for consumers, it is anti-theft, anti-counterfeiting, and the aesthetics of the carton can still be preserved after opening. We recently interviewed several users of cartons with easy-to-tear designs. They have expressed that this form of packaging is deeply loved by consumers and will be used by more manufacturers on product packaging. Haoliyou Foods Co., Ltd. launched the "Holi Good Mushroom Coulee" product, using the "easy-opening line" on the front of the carton pack. The product's paper box has a plastic inner bag inside, and the packaging bag has a very beautiful cartoon design. Ms. Yin, the head of the marketing department of Hao Liyou, tells us that the design of the easy tearing line on the front of the package enables consumers to easily open the carton. The beautiful cartoon pattern on the inner package can be fully displayed in the eyes of consumers and bring the same surprise to consumers. Products using this packaging have been popular with consumers since they were introduced at the end of last year. The top of Nestle's "Nestle Coffee" carton is also designed with an "easily tearable line". Consumers can easily open the package through the "easy tear line" setting on the package. The relevant person in charge of Nestle told us that the design of the easy tear line on the outer packaging carton of "Nestee Coffee" was mainly for the benefit of consumers. This kind of packaging design has a destructive effect on the packaging after opening, which prevents the repeated use of the packaging to a certain extent and effectively prevents some counterfeit products from reusing the packaging. The most innovative aspect of the package is that tearing off the tear strip allows the lid to be inserted into a pre-designed socket, and the pattern can be reconstructed from the surface to a complete product, maintaining the integrity of the package to a certain extent. In addition, the packaging cartons for “Qian Ai Mo†chocolates and the “Baiki†chocolate-coated biscuits for carton boxes produced by Shanghai Jiage Foods Co., Ltd. are also designed with similar tear lines. . The design of the easy-to-fuse line greatly facilitates the use of consumers, and it also brings small surprises to consumers. It has played a very good publicity role in the sales of products. However, in the production process, there are also some problems with such cartons, such as: easy tearing of the tear line, tearing of the edge of the mouth, and the like. This makes end-users have strict requirements on their postpress processing technology when selecting carton suppliers.
