I believe everyone has tried instant noodles before. You should know about instant noodles fibre drum It's completely paper, right? Do you know the material composition of paper bucket packaging? So please follow the editor below to learn more.

Food packaging buckets do not dissolve harmful substances. PC polycarbonate, PP polypropylene, and ABS are all paper block copolymers embedded in pan pib ps. The materials themselves are non-toxic and have a melting point of over 200 degrees. They will not decompose when boiled in water, but many additives are added during the molding process. For example, eco-friendly paper buckets are reinforced, toughened, anti-aging, anti-oxidation, and plasticizers, which themselves are not toxic. The content of food grade plastic additives is strictly limited, and they are also relatively volatile when released.

Number 3: Meaning: This number represents PVC. This type of material, powder foam packaging bucket material, has a relatively hard texture and is often used to manufacture food boxes, water pipes, and building materials. It is widely used in daily life.

Usage guide: Food boxes made with this ingredient are only suitable for storing dry and low moisture foods, such as rice and noodles. PVC has weak high temperature resistance, therefore, before heating food, it is necessary to transfer the food to a suitable container.

Number 6: Meaning: This is the symbol of polystyrene. This material, sometimes in the form of foam, is mainly used to make disposable lunch boxes, water cups and tableware.

Usage guide: Among all types of food packaging materials, polystyrene has the lowest melting point. Although it can be used to hold warm food, do not directly heat food boxes made of this material.

Number 7: Meaning: This number represents materials other than PVC and polystyrene, or synthetic materials of various plastic materials. If the raw material of the food box is polycarbonate (containing BPA), this number will appear on the product.

Usage guide: There are various materials for this type of food box, and their heat resistance and storage methods are also different. Before use, be sure to carefully read the product instructions and strictly follow the manufacturer's guidance.
