Corn starch resin replaces the prospects of plastic packaging materials

I. Corn starch resin is promising for replacing plastic packaging materials

At present, many countries in the world are conducting research to replace existing plastic packaging with "biodegradable resins." Recently, the "corn starch resin" successfully researched in Japan has broad prospects for development. This resin is made from corn and plasticized. The packaging material made from it can be disposed of through burning, biochemical decomposition, insect feeding, etc., thus eliminating the hazard of “white pollution”.

At present, the quantity of plastic bags produced by corn starch resin in Japan is almost the same as that produced by plastic grains.

Globally, about 100 million tons of plastic products are produced each year, of which 30 million tons of disposable packaging materials, to solve the pollution caused by these materials will cost a lot of social costs. If corn resin can successfully replace some of the packaging plastics, it is estimated that there will be a market worth US$10 billion a year.

Second, the commodity "over-packaging" is not desirable

Putting an end to excessive packaging can not only greatly reduce the source of plastic packaging waste, but also greatly save the earth's resources. For example, under the conditions of rational choice of packaging, it is entirely possible to reduce the multilevel of sales packaging. Reuse of plastic packaging is also a way to reduce the source of packaging waste

Third, adhere to the reuse of plastic packaging

In fact, the reuse of plastic packaging is an effective method for transport packaging. In terms of sales packaging, there is also the possibility that the daily consumer goods with large sales volume and wide range can be packaged for reuse or refilled. For example, the foreign detergent industry is rapidly turning to concentrated products and related refilling forms; fabric softeners have been supplied in Europe and North America in the form of refilled enrichment products for many years, gaining widespread consumer acceptance.

Fourth, recycling of plastic packaging waste must take a comprehensive approach

Because not all plastic packaging wastes have the value of recycling, especially for large amounts of mixed plastic packaging wastes and packages that contain toxic substances (such as medicine bottles, pesticide bags, and medical plastic waste). Recycling methods to deal with, but rely on chemical recycling or energy recycling law.

V. Unlimited potential for biodegradable plastic packaging

At present, the country has included degradable plastic packaging as a priority development project. Degradable plastic packaging has great market potential in fields such as agriculture, daily chemicals, medicine, and food. According to statistics, in 2000, the output of plastic packaging in China was more than 3 million tons, and nearly 2 million tons of plastic waste was generated. Therefore, the development prospects of degradable plastic packaging are promising.

However, it should be pointed out that degradable plastics cannot be regarded as a panacea for solving plastic packaging wastes, and there are still limitations in the application performance of packaging, especially whether it can adapt to a variety of food packaging, and it must be studied.
