Trivia About Thermoplastic - A Fun Discovery

By Lenna Stockwell


One of the things rather common for us to use would have to be thermoplastic. You'll be surprised at how many things made of thermoplastics there are that we use - from water bottles, nylon stockings, our kid's baggie for packing his or her lunch and even the PVC pipes which can be found beneath our homes. For different types of thermoplastic packaging and fun facts, read on to learn about them.

For our starting trivia - do you know that the word "plastic" is an English word with its roots coming from the Greek language? It hails from the Greek word "plastkos" which means moldable which is exactly what these thermoplastics are - easy to mold upon the application of heat unto these polymers. Thermoforming companies create things from thermoplastic by using thin sheets of plastic which is exposed to heat and then molded into products of different shapes along with types of thermoplastic packaging too.

There are plastics which are actually biodegradable though probably not how you think of it to be. As the common perception of people about the term "biodegradable" is that it is compostable where when one is biodegradable it naturally breaks down into compost. The same is not true with plastic however. Although biodegradable plastics can be broken down, only a few types actually compost down into the organic substance which is called humus. One good thing though is that thermoplastics come amply recyclable which is why one should always note to place them in recycling bins.

One type of thermoplastic is the most common of plastics and that is "polyethylene." It is this type of plastic that is responsible for the manufacture of millions of products annually including the plastic bags and plastic bottles you use quite often. And this polyethylene also has several varying types which you will find classified by polymer names just like the polyethylene terephthalate (PET or PETE), the low-density polyethylene or LDPE and the high-density polyethylene or HDPE. This particular plastic is not compostable making it an essential addition to the "must recycle" list in order to ensure that its environmental impact is reduced.

Do you know that all thermoplastics come with designated codes just as both the polyethylene terephthalate and the high-density polyethylene have their corresponding special resin codes as well? For these two, 1 or 2 are their resin codes. They are both generally welcomed to be tossed into recycling bins of most every reuse and recycling companies in the United States. As for other thermoplastics with different resin codes, some cities ensure that they too are accepted, but not all cities allow other plastics into the recycling bin.

Recycling is important for plastics and not only because it reduces landfill waste and helps protect the habitats of marine and land animals. It takes much less energy to recycle thermoplastic products and thermoplastic packaging than it does to create plastic items from "scratch." In fact, every water bottle that is recycled is said to save enough energy to power a 60-Watt light bulb for several hours, and that's just one single bottle.
