Both PE (polyethylene) and PVC (polyvinyl chloride) are common plastic materials that have some differences in terms of environmental protection.

On the whole, PE material is generally considered to be more environmentally friendly than PVC. Here are some key differences:

1. Emissions in the production process: The production process of PE usually produces less harmful gases and wastes, which is more environmentally friendly than the production of PVC.

2. Degradability: PE decomposes relatively quickly in the natural environment, especially film products such as PE bags. In contrast, PVC breaks down more slowly and may spend longer in landfills.

3. Toxic substances: The manufacturing and handling process of PVC may involve some toxic substances, such as chlorine gas, which may pose risks to workers and the environment. The manufacturing process of PE involves relatively few chemicals.

4. Recyclability: PE is generally easier to recycle and reuse than PVC because PE materials are more easily regenerated.

Although PE is considered more environmentally friendly in many ways, the choice of material should also consider the needs of specific applications. For example, PVC may have better chemical and weather resistance in some cases, making it more suitable for certain applications.
