First, the function of packaging and
We discuss green packaging and must talk about packaging.
In today's commodity economy and society, a large variety of goods are produced. Commodities are products that are produced for exchange, and thus there is a process of commodity circulation. In order to meet the needs of circulation, various types of packaging are used, such as storage and transportation packaging (also known as transport packaging), sales packaging, etc.; packaging is an indispensable part of goods, no packaging, circulation, exchange of goods The function is not possible to achieve; unpackaged goods are unthinkable, even if a very small number of so-called shirtless goods, its transportation, storage process, it is not possible not to use packaging, but did not use sales packaging only. It can be said without exaggeration that without packaging, there would be no commodities and there would be no development of our market economy. No commodity can be a good product without good packaging. The view that indiscriminately criticizes packaging and opposes packaging is very wrong, and the view of despising packaging is also very harmful. Some older friends must remember that in the 1970s and 1980s, our country had just vigorously developed the initial stage of the market economy. In order to change the major losses caused by the poor packaging of China's export goods, we formulated a whole set of rapid changes to us.†"First-class goods, second-class packaging and third-class prices" have achieved remarkable results in their policies and policies. It is true that the reference to first-class goods is indeed debatable, but the case of second-class packaging that leads to third-class prices can be found everywhere. In particular, many “bow-shirted goods†in the agricultural and sideline products that were exported at that time were exquisitely adopted by foreign companies. After the sale of packaging packaging doubled in value, they also obtained a lot of excess profits, and we will be part of this should have belonged to their own wealth, freely surrendered to others. The experience of history deserves our great attention.
Appropriate application of packaging not only creates great benefits for the producers of goods, but also brings many benefits to consumers. For example, after rice is packed in plastic film bags, especially in barrier plastic film bags, the shelf life can be increased from about one month in bulk to 3-6 months or even more than 1 year; after vacuum pickling, pickles, etc. The quality of products has a significant increase in prices, but such small packages have the advantages of long storage time and convenient use, and because of their moderate weight, they avoid the spoilage of the rest of the meal after opening, which in turn reduces the consumer’s economy. The burden was therefore generally welcomed by the society. The shirtless packaging of traditional agricultural and non-staple food such as pickled mustard and pickles, and the large packaging with a weight of 500g or more were becoming less frequent, and some even disappeared. Many off-site sales of agricultural and sideline products benefit from the development of packaging materials and packaging technology. Although the geographical boundaries of the production of agricultural and sideline products are continuously decreasing in the highly developed science and technology, the geographical boundaries still exist. The old saying “South Orange†is still playing a role in many places, such as being called “fruitsâ€. The fresh lychees of the king can still only be produced in the south of the subtropical zone, so that only after we use the polystyrene foam insulated storage container, this kind of corruptible fresh fruit can be shared by the people all over the country and for the majority of the people. . And so on, there are many. Through the above example, it is not difficult to see that rational use of packaging is essential for improving the competitiveness of products, improving the economic efficiency of enterprises, or better satisfying social needs and protecting the rights and interests of consumers. It is believed that the problem is not whether the goods need to be packaged, but how to rationally use the packaging, that is, to develop and apply green packaging.
Through decades of efforts, our packaging industry has made considerable progress. Although there are still considerable gaps in many places compared with the developed countries of the world, many fields have reached or approached the world's advanced level. The development of a market economy has made a tremendous contribution. This is very gratifying. In the past two decades, the development and application of the packaging industry have eloquently demonstrated that packaging is a major player in the development of a market economy, and it is also an important aspect that we can not ignore in the future development of the national economy.
Second, white pollution is a special product under specific historical stages. We should learn profound lessons from it.
In the 1990s, the so-called white pollution that was caused by packaging waste represented by EPS disposable tableware and other serious environmental hazards occurred in China. Because the stability of plastic itself is good, its waste is scattered in the natural world, causing serious problems. Visual pollution, but also caused serious harm to the ecological balance can not be ignored. At first glance, the environmental pollution caused by large amounts of plastic waste is due to the fact that too many plastic packaging materials are used. Therefore, it was proposed that “paper-based plastic molding†and “wood-based plastic molding†should be used to limit or prohibit the use of plastic packaging materials. These views are extremely one-sided and very wrong. They must be given attention and clarified.
Plastics, as a new type of synthetic polymer material that came out in the early 20th century, has been favored by all walks of life with its wide variety, excellent performance, convenient molding, and low price, and it has penetrated into industry, agriculture, and national defense for decades. The application of scientific research and even people’s lives in packaging has been particularly effective. The amount of plastics used in packaging accounts for more than 20% of the total output of plastic products. In packaging materials, the use of plastics is second only to paper. Far more than traditional packaging materials such as metal, glass, and wood, the product has leapt to the second place, and it still develops at a rate that other packaging materials do not have. The irreplaceability of plastics in the packaging field has become increasingly prominent. The cases are numerous and can be described by the people all over the world. Compared with the industrialized countries, our plastic packaging is not used too much, but it is quite rare. In the late 1990s, when serious “white pollution†occurred in China, the per capita plastic packaging material usage was only about 1 kg, which was only one or two-thirtieth that of foreign industrial countries, and China’s “white pollutionâ€. Compared to foreign industrialized countries, far worse than the developed countries, what are the reasons? The author believes that the main reason is not that our plastic packaging is used too much, but that our general people have poor environmental awareness in the past. Many people have the bad habit of throwing litter at random; the government does not have sufficient control over policies and regulations. Inadequate guidance and waste recycling networks are not sound enough. This is where the crux lies.
