PP plastic is a kind of lightweight plastic, which is mostly used in the home appliance and automobile industry and is used for food packaging products, mainly because of its strong hygiene. The maximum cold resistance temperature of PP plastic bento lunch boxes is -35 degrees Celsius. Once the temperature is below -35 degrees Celsius, PP plastic products will become brittle.
