With the continuous development of science and technology and the continuous improvement of people's living standards, people 's requirements for food packaging bags are becoming higher and higher. Of course, the most popular candy packaging for children is no exception. Now people's life rhythm is getting faster and faster. People pay more attention to the convenience and beauty of food packaging. At this time, self-supporting bags and re-sealable bags have been replaced by traditional candy packaging . Because of their ease of use, people will particularly like it. On the one hand, self-standing bags are undoubtedly the perfect solution for home use for opening or disassembling confectionery ; on the other hand, resealable bags eliminate people's practice of transferring confectionery to another container. Of course, stand-up pouches and resealable pouches can be combined into one, which is more convenient and practical for users. Nowadays, confectionery packaging of re-sealable bags and multi-purpose bags has been popularized in the market . I believe that in the near future, in order to meet the market demand and people's requirements for confectionery packaging, more confectionery packaging to meet customer experience will emerge in large numbers.
