Maybe, now you don't know much about the scope and reasons for the use of plastic bags and reusable bags, but the promotion of the use of reusable bags is the reason above. It can be easily decomposed under natural conditions, or it will not give environmental It brings great pollution, because the environment is the place where we live. Without the existence of the environment, where will our good life come from, so the use of environmental protection bags is very advocated!

Common environmentally friendly food packaging materials are:

1. Degradable plastic:

Plastics are generally difficult to degrade, and there are a lot of plastic waste buried in the ground that can not decompose for several years. Degradable plastic refers to a plastic whose chemical structure changes under a specific environment that causes performance loss within a specific time. The development of degradable plastic packaging materials and the gradual elimination of non-degradable plastic packaging materials is the general trend of world science and technology development and one of the hot spots in material research and development. Due to the ease of processing and molding of degradable plastics, the price is decreasing day by day, resulting in a sharp increase in the use of degradable plastics for packaging. It is the most common environmentally friendly food packaging material;

2. Metal packaging materials:

Since metal packaging materials are easy to recycle and dispose of, their wastes have less pollution to the environment than plastics and paper. Commonly used metal packaging materials are tinplate and aluminum, which are widely used in the manufacture of packaging cans for food and beverages;

3. Glass packaging materials:

Milk, soft carbonated drinks, alcohol and jams are generally packaged in glass containers, and some cooking utensils and tableware are also packaged in glass. The main features of glass packaging materials are beautiful, hygienic, anti-corrosion, low cost, and inert materials with little environmental pollution; their disadvantages are fragile, bulky, and expensive.

4. Paper bag recycling:

Since the paper product packaging can be recycled again after use, a small amount of waste can be decomposed naturally in the natural environment, and has no adverse impact on the natural environment, so the world recognizes that paper, cardboard and paper products are green products, which meet the requirements of environmental
