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.
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.
Of the resin identification codes, the most common would have to be 1 where it identifies thermoformed packages as well as products made out of polyethylene terephthalate. Plastic water bottles and soda bottles are amongst these products. Many of the recycling centers in the country welcome these products and in some states if you turn these bottles in to a specific type of recycling center you can have a deposit refund.
Several words and terms are still associated with thermoplastic including PVC which is "polyvinyl chloride." Of the thermoplastic, this one is the widely used type. Some other common types of thermoplastics are acrylic, nylon and Styrofoam. These plastics are all polymers which mean that its molecules are made up of large chains of monomers. Monomers refer to molecules which are capable of being bound together chemically. While there are some polymers which are naturally occurring, some are synthetic and are made by chemists.
