WHAT IS THE SPI RESIN IDENTIFICATION CODE?
Posted by: Jeff Knapp
In 1988, The Society of the Plastics Industry (SPI), now known as the Plastics Industry Association, created the Resin Identification Code (RIC) system. This system was developed to provide a consistent national program to help sorting line workers identify post-consumer packaging types using the six basic packaging resin classes. Contrary to popular belief, the codes weren't intended to be consumer-facing recycle symbols for plastics. The RIC system was supposed to be used to identify the types of plastic resin used to make common products like bottles and other packaging during the processing stage before recycling.
