Commonly used plastic tableware is basically made of polyethylene and polypropylene as raw materials. This is the majority of the national health sector recognized the non-toxic plastic, the market sugar boxes, tea trays, rice bowls, cold water bottles, bottles and so on are such plastic. But polyvinyl chloride, which is similar to the molecular structure of polyethylene, is a dangerous molecule, and a rare liver hemangioma is found to be associated with people who often contact PVC. Therefore, when using plastic products, we must pay attention to what is the raw material? When there is no product manual at hand, the following methods can be identified: where the touch of smooth touch, flammable fire, burning with yellow flame and paraffin-flavored plastic products, is non-toxic polyethylene or polypropylene. Where feel the feeling of hair sticky, fire difficult to burn, burning green flame, the smell of the nose of the plastic is polyvinyl chloride, not food containers.
Do not choose colorful plastic tableware, according to testing, some of the plastic tableware in the color pattern of lead, cadmium and other heavy metals released in excess of the volume. So try to choose no decorative pattern and colorless and tasteless.
