[0002] As a crucial component of the fast-moving consumer goods (FMCG) sector, the functionality, aesthetics, and cost-effectiveness of snack food packaging have always been a focus of industry attention. Traditional packaging boxes mostly employ rectangular or cylindrical structures, manufactured from materials such as cardboard and plastic through processes like die-cutting and hot pressing. With the upgrading of consumption, the market has placed higher demands on packaging design: it must not only meet basic functions such as pressure resistance and capacity adaptation, but also possess added value such as portability, compartmentalized access, and visual marketing.
[0003] The existing packaging technology for snack foods has the following main defects:
[0004] 1. Limited display effect: Traditional geometric shapes lack visual impact, flat printing cannot highlight the three-dimensional sense, brand recognition is limited, and it cannot meet the display needs of modern retail scenarios.
[0005] Second, the production cost is relatively high: complex and irregularly shaped packaging relies on splicing multiple pieces of material or processing with special molds.
