Decrypting PP5 plastic lunch box: Safety or Danger?

Plastic lunch boxes with PP5 refers to the use of polypropylene copolymer made of lunch boxes. PP5 is a kind of polypropylene, with good heat resistance, cold resistance and corrosion resistance, suitable for food packaging. PP5 is often used to make food containers, such as lunch boxes, cups, etc.

PP5 is a safe food-grade plastic that has a melting point of up to 167 ° C and can be sterilized and microwave heated at temperatures above 100 ° C. At the same time, PP5 has good corrosion resistance to acids, alkalis and fats and other substances, and will not react chemically with food to ensure food safety. In addition, PP5 also has good sealing properties, which can effectively prevent food contamination and deterioration.

While PP5 has many advantages, it also has its limitations. For example, PP5 has relatively poor wear and impact resistance and is not suitable for packaging that needs to withstand heavy pressure or beating.

PP5 for plastic lunch boxes is a safe and durable food packaging material, but it is also necessary to pay attention to its characteristics during use to avoid losses caused by improper use.
