'''Resin identification codes''' are [[symbol]]s identifying the type of [[plastic]] an item is made of. They were created in 1988 by the Society of the Plastics Industry, Inc to make the [[recycling]] of plastics easier.<ref>http://www.americanchemistry.com/s_plastics/doc.asp?CID=1102&DID=4644</ref>
The symbol consists of the triangular recycling symbol with a [[number]] and [[acronym]] in the middle. There are seven symbols, using the numbers one through seven.
The symbols are:
*1- PETE: Used primarily in [[bottles]], for products such as [[water]], [[juice]], [[ketchup]], and others
*2- HDPE: Used for [[milk]] containers, detergent bottles, etc.
*3- PVC: Best known for its use in PVC piping, and difficult to recycle
*4- LDPE: Used largely where flexibility is necessary- plastic containers, plastic shopping bags, etc
*5- PP: Also used in containers, such as for [[yogurt]] and at deli counters
*6- PS: Used primarily in [[foam]] packaging and insulation. Styrofoam is made from it
*7- Other: This is not a specific plastic, but a mix of the above, or a different kind not included in the identification codes. "Other" plastics are used in some large juice containers and reusable containers, and in "plastic lumber."<ref>http://www.americanchemistry.com/s_plastics/bin.asp?CID=1102&DID=4645&DOC=FILE.PDF</ref>
