Knowing Your Plastics: Recycling Symbols No. 1 to 7

plastic resin identification codes

Have you ever wondered what the number inside the arrowed triangle means at the bottom of a plastic product? That logo printed on your plastic is known as a Resin Identification Code or RIC, which a set of symbols used to identify the type of resin from which a plastic product is made. Created by The Society of the Plastics, the system was introduced to U.S. recycling facilities in the late 1980s as a method of reprocessing plastics for further use and manufacturing. Today, the resin code system has become a useful tool for consumers after an increased public awareness of recycling.

What is Resin?

Before plastic is transformed into a product, it starts out in the form of tiny pellets known as resin. Resin is the base of the manufacturing process and have various properties. The pellets undergo a molding method where the plastic is transformed; but the way a product is manufactured depends on the type of resin used. For example, the forming process from P.E.T. resin will be different from the forming process of polystyrene resin, which is why the RIC system is important.
