Polyethylene terephthalate (PET) resin, designated with the #1 resin identification code (RIC), is the most common resin used to make plastic bottles and jars, including water bottles, soda bottles, and other beverage containers, as well as jars for food such as peanut butter and mayonnaise. It is also used to produce cups, clamshells, egg cartons, and other thermoformed packaging. Recyclable PET is also generated from industrial and construction and demolition sources. Manufacturers generate strapping, pre consumer preforms and finished bottles, and scrap from thermoform operations. Construction and demolition projects also generate carpet with PET face fibre. PET is also used as label release liner for adhesive products and would therefore be generated in labelling facilities.
