Question

What is a resin code? What is the need to display them on plastic articles?

Answer 1

1. The resin code is a set of symbols appearing on plastic products that is helpful in the identification of the type of polymer used to make that product.
2. Platic needs to be recycled or disposed of safely. Each plastic is composed of a different polymer or set of molecules. Different molecules do not mix when plastics are recycled. For this reason, plastics need to be segregated before recycling. These resin codes help in the easy segregation of plastic products to be recycled.
