What is food grade polyethylene? How much temperature can it withstand? Will poison be released at 100 degrees Celsius?
132-135112100
Food grade polyethylene refers to polyethylene plastic products that meet the hygiene standards for food packaging. Polyethylene plastic products can withstand temperatures that do not exceed their melting point. High density polyethylene has a melting point range of 132-135 , while low density polyethylene has a lower melting point (112 ) and a wide range. No toxins will be released at 100 degrees Celsius.
polyethylene PE--100~-70C
Polyethylene (PE) is a thermoplastic resin obtained by polymerization of ethylene. In industry, it also includes ethylene and a small amount of - Copolymers of olefins. Polyethylene is odorless, non-toxic, wax like in hand, has excellent low temperature resistance (the minimum use temperature can reach - 100~- 70 C), good chemical stability, and can withstand the erosion of most acids and bases (not resistant to oxidizing acids).

Commonly used polyethylene can be divided into low-density polyethylene (LDPE), high-density polyethylene (HDPE), and linear low-density polyethylene (LLDPE). Among the three, HDPE has good thermal, electrical, and mechanical properties, while LDPE and LLDPE have good flexibility, impact properties, and film forming properties. LDPE and LLDPE are mainly used for packaging films, agricultural films, plastic modification, etc., while HDPE is widely used in various fields such as films, pipes, injection daily necessities, etc.

Polyethylene is insoluble in general solvents at room temperature, but can dissolve in small amounts in solvents such as toluene, amyl acetate, and trichloroethylene above 70 . Low water absorption and excellent electrical insulation.
