You may feel unfamiliar with packaging bags, but I believe you are very familiar with plastic bags. Like packaging bags, the main function of plastic bags is to hold various items in daily life. The application scope of packaging bags is quite wide; they can be used wherever bags are needed.
We often use shopping bags when buying vegetables in the market. They can not only hold vegetables, but also have good uses in aquatic products—they can package various aquatic products. In addition, plastic bags often appear in the packaging of animal feed. In crop production, the plastic used as greenhouse material in winter is plastic bags. It can resist the erosion of cold wind and reduce the impact of hail on crops, making it one of the most commonly used plastic products in agricultural production.
Packaging bags usually refer to inner packaging bags, such as the food we often eat, such as egg yolk pies, mooncakes, preserved plums, candies, etc., all of which are a type of inner packaging bags. The application scope of packaging bags is very wide, and they are most commonly used in industries such as pastries, candies, roasted nuts, biscuits, milk powder, and electronics.
Different from ordinary plastic products, packaging bags are colorless, tasteless and non-toxic, making them a favorite storage bag for consumers. Packaging bags can not only be used for packaging in the electronics industry, but also for food packaging. They have strong bearing capacity, high tensile strength and good tension; high transparency and good luster; high softness and good touch; good oil resistance and solvent resistance, and can be heat-sealed and printed; low air permeability coefficient and good gas barrier property.
