Experts said: "1" highest heat-resistant 45 °C: on behalf of PET (polyethylene terephthalate), the general mineral water, carbonated drinks and functional beverage bottles are used in this material. Suitable for warm or cold drinks, the highest heat-resistant 45 °C, a high temperature easily deformed, may dissolve some of the harmful substances, do not directly into the bottle of boiling water.

"4" is not strong heat resistance: on behalf of LDPE (low density polyethylene), plastic wrap, plastic film, etc. are mostly used in this material, if wrapped with plastic wrap food heating, food oils easily in the plastic wrap Harmful substances dissolve out.

"5" resistant to 130 °C high temperature: on behalf of PP (polypropylene), more than 95% of microwave oven lunch boxes made of this material, poor transparency, some lunch box box body made of PP, box cover but PS (polystyrene) Manufactured, the PS has good transparency, but it is not resistant to high temperatures, so it cannot be put into the microwave oven together with the box.
