Plastic Resin Identification Guide
RRS was proud to support the development of the Plastics Resin Identification Guide with the Institute of Scrap Recycling Industries (ISRI).
Plastic processors and packaging designers will find it useful with resin descriptions, end market data, scrap specs, converting processes, problematic/lookalike packaging, safety tips, and more. Included is a special section on thermoforms.
