In addition to the need to satisfy the contents of the packaging, the plastic packaging bag also meets the requirements for the packaging function of the product. Most of it is in color bags, but the color and other additives are toxic, so be sure to pay attention when using plastic bags: what can be used to hold it, and what can not be used to hold it. In the design of plastic bags, we must meet these basic requirements, and we must pay attention to some problems in the use.
First, the plastic bag should have good wear resistance so that it can be used repeatedly without damage.
Second, the packaging bag must have good practicability. It is necessary to consider the impact of product performance, transportation mode, use environment and storage environment on the product.
Third, colored plastic bags cannot be used to hold high-temperature foods. If it is a food packaging bag, it is also necessary to consider whether the material of the packaging bag is harmful to the human body.
Fourth, plastic bags must have good sealing properties, and different products have different requirements for the sealing degree of the packaging bags.
Fifth, try not to use plastic packaging bags to pack food. Some bags have not been sterilized in the production process. They look clean and actually dirty. These dirty things can also contaminate food.
