There are many kinds of plastic tableware according to their composition, such as high-density polyethylene, polyvinyl chloride, low-density polyethylene, polypropylene, polycarbonate, etc. Plastic tableware with different compositions is suitable for different substances, and the purchase should meet your own needs. The composition of these plastic tableware and their respective applicable occasions should be remembered!
1. High-density polyethylene (HDPE) is suitable for bath products and cleaning products, not suitable for meat and cakes.
2. Polyvinyl chloride (PVC), made of vinyl chloride polymerization, plastic wrap has good transparency, strong adhesion, is not easy to break, and the price is low and low, but it will release toxic substances in contact with oil
When using, it should be noted that it is best not to put foods containing more fat, vegetables and fruits, and refrigerated foods can also be placed. If you use a microwave oven, it is best not to use plastic dishes containing this ingredient, the high temperature will also allow it to release toxic substances.
3. Low-density polyethylene (LDPE) plastic wrap is mostly used to make the inner film of milk cartons and packaging boxes, because it has water-insulating properties, but the heat insulation effect is poor, and it will melt when the temperature exceeds 120 degrees Celsius, so it is best not to heat it. For daily use, it is best to remove the plastic wrap and do not use it in the microwave, otherwise harmful substances will be dissolved.
4. Polypropylene (PP), good transparency, mostly used to make disposable boxes for restaurants, of course, the plastic box made of it can also be put into the microwave oven for heating, this material is the only microwave plastic box, we must see the polypropylene material marked on the box and the word "microwave" when purchasing.
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 the microwave rate, because too high temperature will release harmful substances.
7. Polycarbonate (PC), with good transparency, toughness and strength, is mostly used to make kettles, cups, feeding bottles, etc., but it contains endocrine disruptors such as bisphenol A, which is harmful to developing children and pregnant women
In severe cases, it can lead to congenital intellectual disability and miscarriage of pregnant women, so if parents find that there is PC in the material of the bottle used by their baby, they should stop using it immediately and choose a bottle made of other safe materials.
