Which is better, food-grade plastic pe or pp?

Among food-grade plastics, PP (polypropylene) is usually better than PE (polyethylene), especially in heat resistance and impact resistance. The following is the introduction of PP and PE materials:

1, PP .PP has lower density than PE, and is more resistant to high temperature. Generally, it does not deform or deteriorate at 12 1℃, so it is a good choice in high temperature environment, such as microwave heating and high temperature sterilization.

Physical education class. PE is lighter and more transparent, and its price is relatively lower, but it is not resistant to high temperature and easy to deform, so it is not suitable for high temperature environment or direct contact with hot food.

3. Generally speaking, if you need to use in a high temperature environment or directly contact with hot food containers, such as microwave ovens, lunch boxes or oven utensils, you should choose PP; PE is a good choice if it is only used for packaging refrigerated or frozen food, or if soft and transparent materials are needed.
