What are the most common environmentally friendly food packaging materials?

 Common environmentally friendly food packaging materials are:


1. Degradable plastic:


Plastics are generally difficult to degrade, and there is much plastic garbage buried in the ground that will not decompose for several years. Degradable plastic refers to a plastic whose chemical structure changes in a specific environment that causes performance loss within a specific period of time. The development of degradable plastic packaging materials and the gradual elimination of non-degradable plastic packaging materials are the general trend of the world's scientific and technological development and one of the hot spots of material research and development. As biodegradable plastics are easy to process and shape, their prices are gradually decreasing, resulting in a sharp increase in the use of biodegradable plastics for packaging. It is currently the most common environmentally friendly food packaging material;



2. Metal packaging materials:


Since metal packaging materials are easy to recycle and easy to dispose of, the environmental pollution caused by their waste is less than that of plastic and paper. Commonly used metal packaging materials are tinplate and aluminum, which are widely used in the manufacture of food and beverage packaging cans;


3. Glass packaging materials:


Milk, soft carbonated drinks, wine, and jams are generally packaged in glass containers, and some cooking utensils and tableware are also packaged in glass. The main characteristics of glass packaging materials are beautiful, hygienic, corrosion-resistant, low cost, and inert material, which has little environmental pollution; its disadvantages are fragile, bulky, and more expensive.


4. Paper bag recycling:


Since the packaging of paper products 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. Therefore, paper, cardboard, and paper products are recognized as green products in the world and meet the requirements of environmental protection. Treating white pollution caused by plastics can play a positive role as a substitute.
