PET or PETE is the shortened form of Polyethylene Terephthalate. It has the recycling symbol of number 1, as shown on the left side, and is used widely from drinking bottles to textiles. Let’s take more look at it now.
PET is a form of polyester. In food-related applications, you can often find them in the water bottles, peanut butter bottles, frozen food packaging, household cleaners, etc. In non-food related applications, PET is found in textiles, athletic shoes and sleeping bags.
Strong, transparent, thermo stable, lightweight, impact resistant, good barrier, chemical resistant (except for acetones and ketones), and inexpensive.
PET is compatible with food but incompatible with acetones and ketones.
Anything under 160°F or 71°C.
PET products are recyclable. The first PET bottle was recycled in 1977 and most recycling programs in USA will accept PET bottles. All you need to do is to flatten the bottles so that they save space when you transport it to the recycling company, then let them do the rest. Recycled PET resin can be formed into clothing (fleece jackets, sweater), sleeping bags, carpets, and new containers (both food and nonfood).
