Analysis of the advantages and disadvantages of packaging design

The rational application of packaging not only creates a huge profit for the producers of the goods, but also brings many benefits to the consumers. For example, after the rice is packaged in a plastic film bag, especially in a barrier plastic film bag, the shelf life can be increased from about 1 month in bulk to 3-6 months, or even more than 1 year; after mustard, pickles, etc. The product price per unit quality has been greatly improved. This small package has the advantages of long storage time and convenient use, and because of the moderate weight, it avoids the corruption and deterioration of the remaining part after opening, but reduces the economic burden of consumers. Therefore, it is generally welcomed by the society. The off-site sales of many agricultural and sideline products have benefited from the development of packaging materials and packaging technology. For example, the fresh lychee, known as the king of fruits, can only be produced in the southern subtropics. After the company adopts the polystyrene foam insulation turnover box, this highly perishable fresh fruit can be shared by people all over the country. Through the above examples, it is not difficult to see that the rational use of packaging, whether to improve the competitiveness of goods, improve the economic efficiency of enterprises, or better meet the needs of society, to protect the rights and interests of consumers, is very necessary. The question is not whether the goods need packaging, but how to use the packaging reasonably.

In the 1990s, China experienced the problem of “white pollution” caused by packaging wastes such as disposable foamed plastic tableware. Due to the good stability of the plastic itself, its waste is scattered in the natural world, which not only causes serious visual pollution, but also causes serious harm to the ecological balance. At first glance, the environmental pollution caused by a large amount of plastic waste is too much for the use of plastic packaging. Therefore, some people have put forward the idea of ​​“representing paper by plastic, molding with wood” and prohibiting the use of plastic packaging materials. In fact, these views are extremely One-sided, must be paid attention to, to clarify.

As a new type of synthetic polymer material that was introduced in the early 20th century, plastics has been favored by all walks of life for its variety, high performance and low price. It has penetrated into industry, agriculture, national defense and people for decades. In all aspects of life, its application in packaging is particularly outstanding. The application of plastics in packaging accounts for more than 20% of the total output of plastics. In packaging materials, the application of plastics is second only to paper products, far exceeding the traditional packaging materials such as metal and wood. In the late 1990s, when there was a serious "white pollution" in China, the use of plastic packaging materials per capita was only about one kilogram, about one-thirtieth of that of foreign industrialized countries, and China's "white pollution" compared with it. The foreign industrialized countries are far behind. What is the reason? Xiao Bian believes that the main reason is not that our plastic packaging application is too much, but that the masses of the people have a poor environmental awareness, and many people have littered garbage. Bad habits, the waste recycling network is not sound enough, this is the root of the cause.
