2 HDPE HDPE: used for storage containers and other items. Cleaning is not thorough, do not recycle.
3 PVC polyvinyl chloride: it can only be heat-resistant 81 degrees.
No. 4 PE polyethylene: harmful substances are produced in high temperature. Toxic substances may cause breast cancer, congenital defects of newborns and other diseases when they enter the human body with food.
Polypropylene PP 5: melting point up to 167 C, reusable
No. 6 PS polystyrene: chemicals released from high temperatures.
7 other PC: it is easy to release toxic bisphenol A, which is harmful to the human body. Do not heat when used.
