1. High density polyethylene (HDPE), suitable for bathing products and cleaning supplies, not suitable for meat and cakes, in addition, some families will use plastic tableware containing this ingredient for daily garbage and kitchen debris.


2. Polyvinyl chloride (PVC), which is polymerized by vinyl chloride, has good transparency, strong adhesion, not easy to crack, low price, but it will release toxic substances in contact with oil. When using it, it should be noted that it is better not to put food containing more fat, vegetables and fruits, in addition, refrigerated food can also be put. If you use a microwave oven, it's better not to use plastic tableware containing this ingredient, high temperature will also let it release toxic substances.


3. Low-density polyethylene (LDPE) fresh-keeping film is mostly used to make the inner film of milk cartons and packing boxes, because it has water-proof performance, but the heat insulation effect is poor, when the temperature exceeds 120 degrees Celsius, it will melt, it is better not to heat. In daily use, it is better to remove the fresh-keeping film, do not use in the microwave oven, otherwise it will dissolve harmful substances.


4. Polypropylene (PP), with good transparency, is mostly used to make disposable boxes in hotels. Of course, the plastic boxes made of PP can also be heated in microwave ovens. This material is the only plastic box that can be microwave. Everyone must see clearly the polypropylene material marked on the boxes and the words "microwave".


5. Polystyrene (PS), heat-resistant and cold-resistant, is mostly used to make fast food boxes and instant noodle boxes, but it is not suitable for heating in microwave rate, because too high temperature will release harmful substances, in addition, try not to use it to fill hot food, do not use it to strong acid food.
