Background
With the development of economy and increasing consumption level, food packaging is also endowed with more and more functions, including packability, protection, convenience, display, economy and pleasure. The paper box is the most common packaging material, has the advantages of easy folding, easy forming, easy adhesion, low cost and the like, and is widely applied in the field of food packaging. With the high concern of food safety, food-grade laminating paper is produced and becomes a common food packaging material. The laminated paper is a composite material with plastic particles coated on the surface of paper through a casting machine, has the characteristics of oil resistance, water resistance and heat sealing, and can be used for disposable paper cups, hamburger paper bags, melon seed bags, paper lunch boxes and the like.
The most basic function of food packaging is protection. The structure of the food package must be designed with a view to load bearing, pressure resistance and impact resistance, i.e. to have sufficient strength on its own to resist forces from the inside and outside of the package. The food packaging paper box made of the laminating paper has poor strength and is easy to deform and tear, the protection function is difficult to exert, and the purchase experience of consumers is seriously influenced. The strength of the food packaging carton is improved, and the food packaging carton can be considered from two aspects of materials and structures. The former mainly depends on improving the gram weight of the laminating paper, so that certain cost waste can be caused while the package is heavier; the latter is designed according to the factors of the paper box such as the geometric dimension, the functional structure, the paper pattern direction and the like, but the functions of protection, portability and exhibition are still difficult to achieve on the basis of economy.
