Plastic is one of the common materials in our life, plastic cutlery tray, plastic bottles. Plastic bags, etc. Plastic tableware is one of them and is divided into seven categories. We will see a small triangle at the bottom of the plastic product with a number in it. This number is the national standard number corresponding to each type of plastic tableware.

   01PET polyethylene terephthalate, a common product made of it is a plastic bottle for beverages, and the mineral water bottles and carbonated beverage bottles we see on the market are this material. The shortcomings of this material are also obvious: it cannot be canned with hot water, and it will deform and melt at a high temperature of 70 °C. It is only suitable for canned cold and warm drinks.

   02HDPE is high-density polyethylene. Products using it as raw materials include detergents, shower gels, shampoos, pesticides, edible oils, etc. Plastic bags in large shopping malls and supermarkets are this material.

   03PVC polyvinyl chloride, common polyvinyl chloride products in life include plastic films, plastic boxes, building materials, etc. It is low in price and good in plasticity, so it is very versatile. But its heat resistance is only 81 ℃, and it is rarely used for food storage.

   04LDPE low-density polyethylene: the products made from it include plastic bags and plastic wrap. This material is not heat resistant. Generally speaking, the plastic wrap will melt when heated to 110°C, and the food wrapped in the plastic wrap can easily dissolve the harmful substances in the plastic wrap under the action of grease. Therefore, try not to place the plastic wrap in the microwave oven for heating.

   05PP polypropylene: Common products include juice drink bottles, buckets, trash cans, baskets, and microwave heating boxes. This is the only material that can be heated in a microwave oven. It is resistant to a high temperature of 130 ℃, but the transparency is poor. In daily life, we can use it carefully and repeatedly after cleaning it.

   06PS polystyrene: Our common disposable lunch boxes, cups for drinks in beverage stores, foamed fast food boxes, and instant noodle buckets are all products made from it. It's cold and heat resistant, but it shouldn't be heated in a microwave because too hot can release harmful chemicals. Moreover, such products are also not suitable for containing strong acid and strong alkaline substances to prevent the precipitation of polystyrene.

   07PC and several other types of PCs, our common water bottles and milk bottles are their products. However, because of the presence of bisphenol A, such products have been controversial.
