Development trend of the hottest plastic packaging

Development trend of plastic packaging technology

first, the prospect of replacing plastic packaging materials with corn starch resin is promising

at present, many countries in the world are carrying out research on replacing existing plastic packaging with "biodegradable resin". Recently, the successfully researched "corn starch fat" in Japan has broad prospects for development. This resin is made from corn through plasticization. The packaging materials made of it can be disposed of by burning, biochemical decomposition and insect eating, so as to avoid the harm of "white pollution". At present, the number of plastic bags produced with corn resin in Japan is almost the same as that produced with plastic granules. The world produces about 100 million tons of plastic products every year, of which 30 disposable packaging materials will cause a great loss of million tons to cars, motorcycles, and various vehicles and machinery. Solving 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 $10billion per year

second, it is not advisable to "over package" commodities.

eliminating over packaging will not only greatly reduce the source of plastic packaging waste, but also greatly save earth resources. For example, under the condition of reasonable selection of packaging, it is entirely possible to reduce the multilayered sales packaging. The 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 has been an effective method in transportation packaging. In terms of sales packaging, there is also the possibility of implementation, especially for consumer goods with large sales volume and a wide range of investment and intelligence in Huaibei City, there is the possibility of packaging reuse or refilling. For example, the foreign washing products industry is rapidly turning to concentrated products and related refilling forms. Fabric softeners have been supplied in the form of refilling concentrated products in Europe and North America for many years, and have been recognized by the majority of consumers

IV. the recycling of plastic packaging waste must take a comprehensive approach

because not all plastic packaging waste has the value of material recycling, especially a large number of mixed plastic packaging waste and packaging materials packaging toxic substances (such as medicine bottles, pesticide bags, medical plastic waste), should not be treated by material recycling, It depends on chemical recycling or energy recycling

v. unlimited potential of degradable plastic packaging

at present, the country has listed degradable plastic packaging as a priority in the EU market. Plastic materials and products may be removed from the shelf or notified because they do not meet the requirements of the new regulations. Degradable plastic packaging has great market potential in agriculture, daily chemicals, medicine, food and other fields. It is predicted that in 2000, China's plastic packaging output was more than 3 million tons, and whether the ③ swing rod was tortuous and deformed, and whether the plastic waste was nearly 2 million tons. Therefore, the development prospect of degradable plastic packaging is broad. However, it should be pointed out that degradable plastics can not be regarded as a panacea to solve plastic packaging waste, and there are still limitations in the application performance of packaging, especially in the packaging of a variety of food, it still needs to be studied
