the Plastics Recycling label was developed in 1988 by the Society of the Plastics Industry (now the Plastics Industry Association). This set of signs marks the plastic material identification code on the container or packaging, from 1 to 7, so that people do not bother to learn the similarities and differences of various plastic materials, they can simply join the ranks of recycling work. Each plastic container has a small ID card - a triangular symbol, usually located at the bottom of the plastic container. There are 1 to 7 numbers inside the triangle, each number represents a plastic container, their production materials are different, the use of taboos are also different.
