Plastic binding covers are indeed a common stationary item in our daily lives, typically available in A4 size. They are made from various materials, each with unique properties. The most common materials used for binding covers are PET, PVC, and PP. 

Let's take a look at their composition and differences:

PET binding covers

PET, an abbreviation for Polyethylene Terephthalate, is a type of plastic material known for its flexibility, colorlessness, and semi-crystalline nature. Often used in packaging materials and food containers (such as Coca-Cola PET bottles), PET is a popular choice across industries.

PVC binding covers

Polyvinyl Chloride, or PVC, is another plastic material with a wide range of applications, including binding covers for document protection. However, PVC is more harmful to the environment than polypropylene, both during its lifecycle and after disposal. Containing chlorine, PVC is often manufactured with lead stabilizers and plasticizers (typically phthalates).

PP binding covers

Polypropylene, abbreviated as PP, is a plastic material that resembles a smooth, flexible, tear-resistant, and scratch-resistant sheet. Considered one of the most environmentally friendly plastics, PP contains only carbon and hydrogen, producing only carbon dioxide and water when burned.
