The Resin Identification Code (RIC) is a technical standard with a set of symbols appearing on plastic products that identify the plastic resin out of which the product is made. [1] It was developed in 1988 by the Society of the Plastics Industry (now the Plastics Industry Association ) in the United States, but since 2008 it has been ...
Recycling codes on products. Recycling codes are used to identify the materials out of which the item is made, to facilitate easier recycling process.The presence on an item of a recycling code, a chasing arrows logo, or a resin code, is not an automatic indicator that a material is recyclable; it is an explanation of what the item is made of.
The recyclability of plastic is determined by its composition; there are seven different types of plastic that are identified using a resin identification code (RIC).
HDPE has SPI resin ID code 2. High-density polyethylene (HDPE) ... HDPE is commonly recycled, and has the number "2" as its resin identification code. In 2008, the ...
Polypropylene has the number "5" as its resin identification code: [58] Repairing. PP objects can be joined with a two-part epoxy glue or using hot-glue guns.
These resin identification codes (RIC), are used internationally. [52] They were developed in 1988 by the Society of the Plastics Industry (now the Plastics Industry Association ) in the United States, but since 2008 have been administered by standards organisation ASTM International .

LDPE has SPI resin ID code 4 Schematic of LDPE branching structure. Low-density polyethylene (LDPE) is a thermoplastic made from the monomer ethylene.It was the first grade of polyethylene, produced in 1933 by John C. Swallow and M.W Perrin who were working for Imperial Chemical Industries (ICI) using a high pressure process via free radical polymerization. [1]
