(Summary description)I believe many people do not know the difference between food packaging bags and packaging bags. In fact, there are many differences between the two. First of all, in terms of raw materials, food packaging bags should be made of food-grade plastic film, which is composed of multiple layers of composite film, usually called rigid plastic, transparent or printed. Secondly, when using food packaging bags, relevant information must be indicated, namely the name of the food, food ingredients, nutritional ingredients, implementation standards, shelf life, storage methods, eating methods and manufacturer information.

Food packaging safety is a worldwide problem. QS (QualitySafety) is the abbreviation of QualitySafety. The dissolution of packaging materials is the key to food safety and health. As early as 1980, the world-renowned food packaging expert Conorreliy discussed this in the book Metal Contamination of Food. In recent years, the HACCP safety system has also stipulated this.

Paper packaging. Paper is an ancient and traditional packaging material, but it is not safe to ignore hidden dangers. The main reason is that impermeability/sizing agents, fillers and other chemicals (to make the paper opaque), bleaches, dyes, etc. are added in the pulp papermaking process. Rosin soap, kaolin, calcium carbonate, titanium dioxide, zinc sulfide, barium sulfate and magnesium silicate are used as fillers. Calcium sulfite, liquid chlorine, hypochlorite, sodium peroxide and hydrogen peroxide are used as bleaching agents. Water-soluble dyes and pigments are used as dyes. The former has acid dyes, basic dyes, and direct dyes, and the latter has inorganic and organic pigments.

2. Plastic packaging. Plastic is a widely used food packaging material. There are two types of plastics: thermoset plastics and thermoplastics. The former includes urea resin UF, phenolic resin PF, cyanamide resin MF; the latter includes vinyl chloride resin PVC, polyvinylidene chloride resin PVDC, polyethylene PE, polypropylene PP, polystyrene PS, nylon NY, styrene resin , Styrene resin ABS, polyester resin, such as pets, pens. Different additives are used according to different resins, and adhesives (such as TDI and TDA) are used to make composite materials.
