PET is the short form for the chemical name of a kind of plastic material: Polyethylene Terephthalate. It is highly flexible, colorless and semi-crystalline resin in its natural state. PET is commonly used for making packaging materials as well as food packaging packs (Coca-Cola PET bottle, for example).
PVC, also extensively know as Polyvinyl Chloride, is the chemical name of a kind of plastic. PVC has a wide range of applications, but with regards to this context, it is used to make some of the binding cover for protecting the document. However, PVC is more environmentally toxic than polypropylene, both during its product life and after disposal. PVC includes chlorine and is often made with lead stabilizers and plasticizers (usually phthalates).
PP is the short form of the chemical name of a type of plastic known as Polypropylene. PP, Polypropylene is like a smooth, flexible sheet of tear-resistant, scratch-resistant, is one of the most environmentally neutral plastics. It contains only two elements (carbon and hydrogen) and generates only carbon dioxide and water when it burns., has a wide range of applications, some of which we would discuss in this article.
DIFFERENCES BETWEEN THE PET, PVC AND PP PLASTIC MATERIALS
We will examine the differences between these plastics concerning their usage in the heavy-duty stapler and binding machine.
|PET binding covers are made from Polyethylene Terephthalate. This plastic form contains chemicals that make it a very preferred option in many industries, including the heavy-duty stapler making industry.||PVC forms of binding cover are made from Polyvinyl Chloride. This plastic material has a portion of its content as Chlorine and Lead, which are both dangerous materials to environmental safety.||The content of this plastic is Polypropylene. This form of plastic primarily contains Hydrogen and carbon. This plastic form has no environmentally hazardous components.|
|PET makes for binding covers that are not easily breakable.It can get fractured, but it would not do so quickly as it is a material with an excellent elastic limit.||PVC makes hard and brittle binding covers.When PVC binding covers undergo stress, they break easily.||A PP binding cover is flexible and tough.Though it can stretch and experience plastic deformation, it does not break easily.|
|Burns slowly and rarely releases any poisonous smoke.There are a few environmental effects caused by the smoke from burning PET.||Burns out quickly, and exhumes poisonous smoke.||Hardly burns and does not produce poisonous fumes.|
|Easily recyclable||Not suitable for recycling||Easily recyclable|
The heavy-duty stapler industry is a vast one, and closely related to its binding machine industry, which uses the binding cover as one of its process materials. Binding covers used to be made from paper in times past, but in these modern times, they are made from plastic materials.
PVC, and PP are the most widely used materials for binding covers used with binding machines.
