Corn starch packaging instead of plastic packaging material prospects.
At present, many countries in the world are in the process of replacing the existing plastic packaging with "biodegradable resin". Recently, "corn starch resin" successfully studied in Japan has broad development prospects. This resin is made from corn, which is plasticized. The cornstarch packaging material made from it by corn starch packaging manufacturers can be burned, biodegradable, and eaten by insects, thus eliminating the harm of "white pollution".
At present, the number of plastic bags made from cornstarch resin in Japan is almost the same as that made from plastic pellets.
The world produces about 100 million tons of plastic products every year, including 30 million tons of disposable packaging materials. Addressing the pollution caused by these materials will cost a lot of society. If corn resin succeeds in displacing some of that packaging plastic, it could be worth an estimated $10 billion a year.
Eliminating excessive packaging can not only greatly reduce the source of plastic packaging waste, but also greatly save the earth's resources. For example, it is possible to reduce the multilevel of sales packaging with the proper choice of packaging. The reuse of plastic packaging is also a way to reduce the source of packaging waste
Adhere to the reuse of plastic packaging
In fact, the reuse of plastic packaging has been an effective method in transportation packaging. In terms of sales, packaging is also a large and wide range of daily consumer goods that have the possibility of packaging re-use or re-filling. For example, the foreign detergent industry is rapidly shifting to concentrated products and related refilling forms; Fabric softeners have been available for many years in Europe and North America in the form of refilled concentrate products and have gained wide consumer acceptance.
Recycling plastic packaging waste must take a comprehensive approach
Because not all have the value of recycled plastics packaging waste, especially a large number of mixed plastic packaging waste and toxic substances of packing materials (such as bottles, pesticide bags, and medical plastic waste) are unfavourable use material recycling way to deal with, and rely on chemical recycling or energy recycling method.
At present, the country has listed degradable plastic packaging as a priority development project, the degradable plastic packaging in agriculture, daily chemical, medical, food, and other fields have large market potential. Data show that in 2000, China's plastic packaging output of more than 3 million tons, and nearly 2 million tons of plastic waste was generated, so the development of degradable plastic packaging has broad prospects.
However, it should be pointed out that the degradation of plastic can not be regarded as a panacea to solve the plastic packaging waste, there are also limitations in packaging application performance, especially in a variety of food packaging that can adapt, but still need to work hard.
