Current Situation of Biodegradable Packaging Materials

Views: 49    

With the development of the economy, the packaging industry is developing rapidly, and various packaging materials continue to appear. At the same time, the environmental problems caused by the application of plastic packaging materials cannot be ignored. In the context of sustainable development, it is imperative to develop biodegradable and environmentally friendly plastic packaging materials by adding additives to improve the composition of the plastic itself. So what is the current status of degradable packaging materials? At present, research on degradable and edible packaging is progressing rapidly in various countries around the world.

In recent years, in Western European developed countries, the popular plastic food packaging bags in the past have been gradually eliminated and replaced by new paper packaging bags and edible packaging bags.

In the United States, 50% of traditional plastic food packaging has been replaced by new paper food packaging. At the same time, researchers from the National Starch and Chemical Company in New Jersey, USA, used corn as a raw material to develop a new type of food packaging material.

Italy, the world's leading food exporter, has clearly announced a total ban on the use of plastic food packaging bags for packaging food. Since 1991, the United Kingdom has used an edible, thin and transparent film to keep fresh fruits and vegetables. And Germany, Switzerland, Australia and other countries are gradually phasing out plastic food packaging bags.

China has also implemented the "Green Packaging" project during the "Ninth Five-Year Plan" period. That is, by controlling the investment direction of the packaging industry, gradually develop volatile and reusable packaging materials.

The research on biodegradable materials in China began in the late 1970s, and a wave of research and development started in the 1990s. The research on biodegradable materials in China began in the late 1970s, and a wave of research and development started in the 1990s. The initial research on biodegradable materials in China mainly focused on the research and development of agricultural mulch. The focus of research and development in the mid-1990s turned to plastic tableware, packaging bags, and garbage bags. During this period, some technologically and economically better products have been developed and put on the market.

So far, China's biodegradable agricultural plastic mulch has been widely used, and packaging materials and products have been in a wide range of applications. There are currently more than 100 companies engaged in the research and development of degradable plastics in China, and some of them have formed a development system that combines production, studying and research.

At present, China is the main production base of degradable plastics in Asia, and its products are exported to Japan, Australia and other countries. Except for synthetic photodegradable and fully biodegradable plastics, the research and development process of degradable plastics in China is synchronized with the world, and the technological level and advanced level are close to or equivalent. Among them, starch refinement, hydrophobic modification technology and starch high filling technology have independent intellectual property rights.
