Note: Not available for food packaging [LDPE low-density polyethylene] " "LDPE is often used in: plastic film, plastic film, etc.): Use: high heat resistance, usually, qualified PE plastic wrap will have hot melt phenomenon during the temperature exceeding 110 ° C, will leave some human body unrecognized plastic preparations The fat in the food is also very easy to dissolve the harmful substances in the plastic film. Therefore, the food is placed in the microwave, first remove the wrapped film wrapped in the package. In the high temperature, harmful substances, there is a poison to enter the human body, may Causes diseases such as breast cancer, newborns, and other diseases.
