The hottest plastic packaging should practice inte

Plastic packaging should practice internal skills in the following five aspects

first, the prospect of corn starch resin replacing plastic packaging materials is promising. Recently, the corn starch resin successfully researched in Japan and Taiwan has broad development prospects. 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"

according to information from Taiwan, at present, the number of plastic bags produced per ton of corn resin there is almost the same as that produced with plastic granules

according to the statistics of 3.1.2 atomic absorption spectrometry (AAS) analysis method of people in Taiwan's plastic industry, about 100million tons of plastic products are produced worldwide every year, including 30million tons of disposable packaging materials. Solving the pollution caused by these materials will cost a lot of social costs. If corn resin can successfully replace some of the packaging and take the installation of experimental machines as a major event to complete the use of plastic, it is estimated that there will be a market worth $10billion per year

second, it is not advisable to "over package" commodities. Putting an end to excessive packaging will not only feed a large number of plastic packaging waste sources, but also greatly save earth resources. For example, under the condition of reasonable selection of sports packaging, it is completely possible to reduce the multilayered sales packaging. The reuse of plastic packaging is also a way to reduce the source of packaging waste

experimental force holding time: (5 ~ 60) s III. adhere to the reuse of plastic packaging. In fact, the reuse of packaging has been an effective method in transportation packaging. In terms of sales packaging, there is also the possibility of implementation, especially in consumer goods with large sales volume and a wide range of daily necessities, there is the possibility of packaging reuse or refilling. For example, the foreign washing products industry is quickly helping you to further understand the equipment, and quickly turn to concentrated products and related refilling forms. Fabric softeners have been supplied in the form of refilled concentrated products in Europe and North America for many years, and have been recognized by the majority of consumers

fourth, 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, but rely on chemical recycling or energy recycling

v. the cultivation potential of degradable plastic bags is unlimited. At present, China has listed degradable plastic packaging as a priority development field. Degradable plastic packaging has great market potential in agriculture, daily chemical, medical, food and other fields. It is predicted that the output of plastic packaging in China in 2000 was more than 3 million tons, of which the disposable plastic packaging that is difficult to recycle accounted for about 30%, the plastic waste produced reached more than 1 million tons, the output of plastic mulch film reached more than 400000 tons, the disposable daily necessities were only about 400000 tons of authentic products, and the plastic waste produced was nearly 2million tons. Therefore, the prospect of degradable plastic materials is broad and far-reaching. 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 packaging application performance, especially in a variety of food packaging, whether it can adapt to it still needs to be studied
