Plastic film refers to a transparent plastic sheet, usually used in the packaging of products and food. It has waterproof, moisture-proof, anti-oxidation, fresh-keeping properties. However, most people do not know the material of plastic film. The raw material of

plastic film is plastic particles, and plastic is a very common material, which is made of synthetic resin or targeted additives. According to different types of plastic particles, plastic film can be divided into polyethylene film, polypropylene film, polyvinyl chloride film and so on.

polyethylene film is the most widely used film, it has durable, waterproof, moisture-proof, transparent and other characteristics, is widely used in all kinds of packaging. The heat resistance of polypropylene film is better than that of polyethylene, so it is used in packaging under high temperature environment. The polyvinyl chloride film has the characteristics of anti-oxidation, oil resistance, acid and alkali resistance, so it is widely used in different fields.

However, with the strengthening of environmental awareness, people have begun to pay attention to the environmental protection of plastic films. Due to the production process of plastic film and the difficulty of recycling, its environmental protection has become one of the problems to be solved urgently in the current society.

as consumers, one of the environmental measures we can take is to reduce the use of plastic film. We can choose to use environmentally friendly bags instead of ordinary plastic bags, use recyclable biodegradable plastic bags, or use more environmentally friendly paper packaging materials.

In short, plastic film is a widely used packaging material. It is made of plastic particles and has different characteristics in different application fields. But we should also recognize the corresponding environmental protection problems, and take practical actions to reduce the use of plastic film, and make our own contribution to the cause of environmental protection.
