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.
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.
In this section, we'll explore the differences between these plastics with regard to their use in heavy-duty staplers and binding machines.
Property | PET binding covers | PVC binding covers | PP binding covers |
Composition | Made from Polyethylene Terephthalate | Created from Polyvinyl Chloride | Composed of Polypropylene |
Environmental | No hazardous components | Contains chlorine and lead; environmentally toxic | No hazardous components |
Durability | Durable, not easily breakable | Hard, brittle, breaks easily | Flexible, tough, doesn't break easily |
Burning | Minimal smoke, low environmental impact | Burns quickly, releases toxic smoke | Hardly burns, no poisonous fumes |
Recyclability | Easily recyclable | Not suitable for recycling | Easily recyclable |
Now that you understand the differences between various plastic binding covers, it's time to choose the right cover for your stationery needs. Consider the properties of PET, PVC, and PP, and select the one that best meets your requirements in terms of durability, environmental impact, and recyclability. Each material has its own advantages and disadvantages, so make an informed decision based on your specific needs and preferences. Happy shopping!
