How to design carton packaging? Cartons are used to hold products, and their outer packaging forms include cartons, paper bags and cartons. Cartons are mostly used to package some products with strong moisture-proof, oxygen-proof and moisture-proof functions. When using carton packaging, we should consider the particularity of the product and have sufficient strength, rigidity and bearing capacity in structure. When designing, we should choose suitable packaging materials according to the characteristics of products, so as to achieve reasonable structure, simple materials, light weight, convenient mechanized production and low production cost, and effectively reduce transportation costs and warehousing and logistics costs. In addition, the appearance of the carton should also consider the printability of the carton, and the process of molding, molding and loading should be considered as much as possible when printing. Cartons have excellent strength, folding resistance, folding resistance, moisture resistance, transparency and other properties. The structural design of carton packaging should technically meet the requirements of product shape, size, characteristics, seller, production technology and environmental protection.
