Which is more environmentally friendly, PE protective film or PET protective film?

Both PE (Polyethylene) protective film and PET (Polyethylene Terephthalate) protective film can be considered relatively environmentally friendly materials, but they have some differences in terms of environmental impact.

1. Raw material source: PE protective film is typically made from plastic extracted from petroleum, while PET protective film is made from polyester fibers or recycled PET. From the perspective of raw material source, PET protective film can utilize recycled materials to some extent, providing better sustainability.

2. Recyclability: PE protective film is generally recyclable plastic, reducing resource consumption and environmental pollution through recycling and reuse. PET protective film can also be recycled, especially when made from recycled PET. Therefore, there is no significant difference in recyclability between the two.

3. Biodegradability: Some specially treated PE protective films can possess biodegradable characteristics and naturally decompose under certain conditions. In contrast, regular PET protective film does not have significant biodegradability.

4. Energy consumption: PE protective film usually requires lower energy consumption in the manufacturing process, while the production of PET protective film may involve higher energy consumption. Therefore, from the perspective of energy consumption, PE protective film may have better environmental performance.

Overall, PE protective film and PET protective film have their own advantages in terms of environmental impact. PE protective film can be recycled and biodegradable, with lower energy consumption. PET protective film can utilize recycled materials, contributing to resource recycling. When choosing protective film, it is important to consider factors such as raw material source, recyclability, biodegradability, and energy consumption to select an environmentally friendly protective film that suits specific applications and environmental needs.
