Application of degradable materials in the food industry

Food does not seem to have anything to do with environmental protection, but in fact it is inextricably linked. Consumers have food in their hands, and what they cannot do without is its packaging. Packaging bags are also one of the "white garbage". With the improvement of environmental protection awareness and the increase of food consumption, it is necessary to choose packaging of environmentally friendly materials. Degradable material packaging bags are widely used environmentally friendly packaging materials at this stage.

Biodegradable materials are mainly used in packaging, chemical fiber, agriculture and animal husbandry, injection and other industries. Among them, they are widely used in packaging applications. In 2013, they accounted for about 60% of the total sales market output. Food packaging materials require biodegradability. The injection molding application market, which is more than 70% of the material packaging sales market, is a key driving force for the increase in requirements for biodegradable plastics.

The requirements for biodegradable materials have increased significantly, including end-user industries, packaging industries, agriculture and animal husbandry, and textile industries. Other industries are also just beginning to apply biodegradable materials. Especially in European countries, diagnosis and treatment of prostheses and medication system software. In plastic and cosmetic surgery, biodegradable materials are widely used in joint replacement, bone fissure fixation plates, bone fracture fillers, human tendons, tendons, and osteorectifiers. After understanding the many advantages of biodegradable materials, many research institutions have just begun to promote the use of such products.

The environmentally degradable material packaging bag is made of two different materials. One is made of renewable materials (such as bagasse, tapioca starch), called "renewable material environmental protection packaging bags." The other is made of decomposable main materials that accelerate the dissolution under the conditions of light or photothermal power generation based on the interaction of the molecular structure in the packaging bag. This environmentally friendly packaging is also called "degradable plastic bag".
