The differences between high-pressure film plastic bags and low-pressure film plastic bags are as follows:

1. The hardness is different:

The high-pressure film plastic bags are soft and shiny, while the low-pressure film convenience bags are hard, and the low-pressure film convenience bags with the same thickness are thicker than the high-pressure film convenience bags.

2. Different load-bearing:

The load-bearing capacity of the high-pressure membrane convenience bag is not as strong as that of the low-pressure membrane convenience bag. Generally, high-pressure film is used in clothing packaging bags, and supermarket shopping bags are all made of low-pressure film plastic.

Uses of high-pressure polyethylene plastic bags:

The invention of plastic bags has brought great convenience to human life, but more and more people don't know how to use them effectively, which leads to the globalization of plastic bag pollution.

Compared with traditional plastic bags, environmental protection bags have the following advantages:

1. The water solubility can be designed and selected, and it is completely soluble in water, non-toxic and pollution-free.

2. Strong stretchability and good tension.

3, high transparency and good luster.

4. High softness and good touch.

5. Good oil and solvent resistance, heat sealing and printing.

6, low permeability coefficient, good gas barrier.

7. Plastic snap buttons or self-adhesive bags can be added.

8. Excellent antistatic performance, no vacuuming, etc.

9. It can be degraded by water, air, sunlight and biology. Usually about a month, it can be decomposed into harmless substances.
