The characteristics of light weight, novel shape, bright color and not easy to break make plastic products more and more favored by parents, tableware, toys, school supplies and many other children's products are made of plastic and its products as raw materials. And how to choose a wide variety of plastic products for children, health and safety, many parents are not clear.

Let's know the ingredients of plastic products first.

According to the chemical composition of the classification, plastic PP polypropylene, PET polyethylene, PVC polyvinyl chloride, acrylonitrile - butadiene - styrene copolymer resin and other types. We don't need to remember these complicated names, we should pay attention to the common material identification symbols of plastic products when buying plastic products for children. Generally at the bottom of the plastic container by the triangle around 1 Arabic numerals. Each number represents a different type of plastic raw material, and each plastic has a different defined use based on its stability and safety; It should be noted that all plastic products are likely to release different levels of excess substances at high temperatures, which may cause different levels of health hazards.

Parents need to pay special attention to the number 7, which stands for polycarbonate (PC) or other plastic type. PC is a kind of material that is widely used, mostly used in the manufacture of milk bottles, space cups, etc., relatively safe. Plastic products made from PC, also controversial because of BISphenol A; The higher the temperature, the faster the release of BPA, so try not to heat plastic products, and do not directly in the sun.

Due to the special demand of appearance, color and function of plastic products, many new additives have been added to the production of plastic. For example, in order to beautiful color, metal substances such as lead are added to plastic products; To increase the expected toughness, plasticizers such as formamide and phthalates are added to the plastic. And all kinds of additives in plastic are not polymerized with plastic, when the plastic is heated or plastic products aging can be released from the plastic and have potential harm to health. Due to children's own sensitivity and unique behavioral habits (hand-mouth habit), the chances of chemicals in plastic entering children's body to produce health effects are greater.

Turns out plastic really has so much damage.
