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.
The process by which a sheet of plastic is exposed to heat at a particular degree until it becomes highly malleable in order to make it viable for forming into many products and package shapes is called thermoforming. What warms up the plastic is either radiant heat or convection before it is forced into a mold. Excess plastic is then removed when it cools down and then you can have your finished product.
Thermoplastic is the type of plastic that is used in thermoforming. There also is a type of plastic known as thermoset plastic, but this type of plastic is a bit different. While thermoset plastics are certainly melted and molded, the addition of heat to this type of plastic permanently changes its chemistry so it can never be melted down again and remolded into something new.
As for thermoplastics, this type is surely recyclable and so can be used and remolded many times over. Thermoplastic also comes in several types where each one actually comes classified with the use of resin identification code. If you have seen a number surrounded by arrows forming a circle before, then this is it. Many materials of all kinds come with it just like plastics, metal products, paper products and glass products even. Recycling centers find this useful as they use these codes in separating items upon their drop off.
The most common resin identification code is perhaps 1, which identifies thermoformed packages and products made from polyethylene terephthalate. This includes plastic water bottles and soda bottles. Most recycling centers around the country will take these and some states offer a deposit refund if you turn them into a specific type of recycling center.
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.
