While many people might not be aware of it, thermoforming companies around the country provide many extremely important services for manufacturing. The creation of custom thermoformed packaging is perhaps the top task that these companies complete for clients. Here are some common terms used by workers in this important industry.
Thermoforming is a term that describes a process by which a sheet of plastic is heated up to a point where it becomes quite malleable and can be formed into a vast number of products or package shapes. The plastic is warmed up using either radiant heat or convection and then is forced into a mold. Once it is cooled, the excess plastic can be removed and you are left with a finished product.
Plastic used in thermoforming is called thermoplastic. If you heard about a plastic type known as thermoset plastic, this one is quite different from the first one. Although it is true that thermoset plastic can be melted and molded too, to add heat to this particular type of plastic means that its chemistry is permanently changed thus disabling its potential to be melted down again and remolded to create a new product.
On the other hand, thermoplastic is highly recyclable and can be used and remolded numerous times. There are many different types of thermoplastic, each of which is classified using a special resin identification code. These are codes that you have seen before; they are simply a number surrounded by a triangle formed by arrows. You see them on all sorts of materials, including plastics, paper products, metal products and even glass products. These codes are used to help separate items when they arrive at recycling centers.
Thermoformed packages and products which are made of polyethylene terephthalate is perhaps the most commonly found items and they carry the resin identification code 1. Plastic water bottles and soda bottles are among these items. In the country several recycling centers accept these items being turned over and a deposit refund may even be guaranteed to you if you turn them to a specified type of recycling center in some states.
Of course several more terms are being linked to thermoplastic juts like "polyvinyl chloride" or PVC. PVC is definitely the most widely used of the thermoplastics. Other common types of thermoplastic are nylon, acrylic and Styrofoam. Now these are the plastics which are polymers - a molecule made up of chains of monomers which are large. Monomers are those molecules capable of being chemically bound together. There are polymers which are naturally occurring but then some of them are created by chemists which make them synthetic.
