PE film is more environmentally friendly than PET film

PE film has some advantages over PET  film in terms of environmental protection. Here are some relevant comparisons and explanations:

1. Materials Renewable energy: PE (polyethylene) film is made of polyethylene, and polyethylene is refined from non-renewable energy sources such as oil and natural gas. In contrast, PET films are made from chemical raw materials such as poly terephthalic acid and ethylene glycol, which rely mainly on fossil fuels and are not renewable.

2. Degradability: PE film can be degradable, especially when a biodegradable PE film material is selected. This means that under the right conditions, PE film can be degraded into smaller particles in a short time and integrated into the natural environment, reducing the impact on the environment. PET film is generally not degradable.

3. Energy and water use: Making PET (polyethylene terephthalate) film requires more energy and water resources, while PE film manufacturing uses less energy and water. Because PE films only need to be manufactured at lower temperatures and pressures, they can reduce the need for energy and water.

However, it is important to note that environmental assessment should consider the entire product life cycle, including production, use, and disposal of all stages of the impact. In addition, when considering environmental factors, it is also necessary to consider the function, performance, and specific requirements of the membrane. Therefore, in practical applications, the selection of suitable membrane materials should consider several factors, including environmental protection, performance, feasibility, and economy.
