While there are many different types of plastic, this material can be broken into two main categories. This includes thermoset plastics and thermoform plastic. They sound similar, but thermoset plastics are those that really cannot be recycled and most of the thermoform plastics can be recycled. The two most commonly recycled thermoplastics include polyethylene terephthalate (PET) and high-density polyethylene (HDPE).
If you've ever wondered why thermoplastics are often identified with a number inside a triangle, this is to help with recycling. These resin identification codes, as they are known, let recycling center employees know which type of plastic was used to create a bottle, package or product. Not all recycling centers accept all types of thermoplastics, but most do accept high-density polyethylene, which has a code of 2, and polyethylene terephthalate, which has a code of 1.
Polyethylene terephthalate or PET (sometimes PETE) is marked with a number one and is used to create many different types of thermoplastic packaging as well as plastic. This is one of the easiest thermoplastics to recycle, and it is often transformed from its original use into items such as polyester clothing, carpet fiber and non-food storage containers.
This thermoplastic was developed by two British chemists back in the 1940s. James Tennant Dickson and John Rex Whinfield found that combing the monomer terephthalic acid with another monomer, ethylene glycol, resulted in a polymer that was strong, resistant to many liquids and quite lightweight. This is why PET is used for water bottles and thermoplastic packaging for various foods. The low weight and low cost of PET make it quite cost effective, and its recyclability makes it one of the more sustainable choices for consumers.
Our other commonly recycled thermoplastic is HDPE, which is the easier to remember name for high-density polyethylene. Like PET, this thermoplastic also can be used to make a variety of products such as containers for laundry soap and shampoos as well as milk jugs and other liquids. It's identified by the resin code 2 and usually is allowed by curbside recycling programs as well as recycling centers. While PET are the bottles we associate cashing in to receive our deposit back, deposits aren't paid for HDPE, but these thermoplastic packages and bottles definitely can be recycled.
For those who need thermoform packaging, such as custom thermoform trays, clamshell packages, custom bottles or blister packaging, it is best to contact a thermoforming company and discuss your options. Using HDPE or PET might be an excellent option for your product, and thermoforming companies can help you find the best type of plastic for your needs.
