PVC is commonly used in: common raincoats, building materials, plastic films, plastic boxes, etc. It is rarely used for food packaging.
Use: This material has excellent plasticity and low price, so it is very popular. It can only heat up to 80 ℃, and it is easy to produce harmful substances at high temperatures, and even release toxic substances during the manufacturing process. If it enters the human body with food, it may cause diseases such as breast cancer and birth defects in newborns. Containers of this material have been less used for packaging food. If you use it, don’t let it get hot. Difficult to clean and easy to remain, do not recycle. Do not buy if it contains drinks.
Note: Cannot be used for food packaging.
LDPE is often used in: cling film, plastic film, etc.
Use: The heat resistance is not strong. Generally, the qualified PE cling film will melt when the temperature exceeds 110 ℃, leaving some plastic preparations that cannot be decomposed by the human body. The fat in food can easily dissolve harmful substances in the plastic wrap. Therefore, when the food is put into the microwave oven, the wrapped plastic wrap must be removed first. Hazardous substances are produced at high temperatures, and toxic substances enter the human body with food, which may cause breast cancer, birth defects and other diseases in newborns.
Note: Use a microwave oven to heat up, do not wrap the food in plastic wrap.
