Plastic packaging materials have not been developed forward with other traditional packaging materials, mainly with the following aspects: (1) Plastic packaging material is superior, wide variety, can adapt to a variety of demand on product packaging For meat foods, it is necessary to use a packaging material with excellent oxygen performance to prevent oxygen in the atmosphere from contacting it, thereby preventing its oxidation deterioration and inhibiting the reproduction of microorganisms, and prolonging the shelf life. The barrier plastic film bag or container is used as a packaging material, which can meet this requirement, fresh fruit and vegetable goods, in the storage and sales process, in the new metabolic state, according to the specific situation of fruits and vegetables, the optional gas permeability is selected. Plastic film bag for packaging. (2) Plastic molding performance is excellent, can be made into a variety of molding methods, suitable for special packaging plastic products for manufacturers and water, agriculture, animal husbandry, and other departments in all walks of life. .
(3) Various plastics for plastic packaging, most of them can produce large-scale industrial production, and therefore supply adequate, and the cost is also relatively low. (4) Plastics for plastic packaging materials, basically all heat-plastic plastics, due to thermoplastic, after use, the waste packaging can be used back to furnace, which is conducive to saving material resources, reducing packaging cost, adapting to environmental requirements (5) in resin During the production of plastic products, the environmental pollution is small, or there is no contamination on the environment, and in production, it is also small, which is also a significant advantage. Due to the existence of a plastic packaging material, it promotes the development of plastic packaging materials, which also promotes great promotion for the development of production and the improvement of people's living standards.
However, a large number of applications of plastic packaging materials also brought a problem that the problem is not affected, that is, the plastic performance is quite stable, which is not easy to return to nature in nature. Since people's environmental awareness is relatively weak during a quite long, a large amount of abandoned plastic packaging materials flow into nature, accumulating the moon, forming a heavy burden on the environment, has a serious negative impact on environmental protection, thus It has come to some blame of plastic packaging materials, and even propose for the right to disable, in a period of time, one: The voices of paper plastic, especially the voices. In fact, this kind of talk is very dark, it is not possible.
The first is the insectibility of performance, the paper product is ruthless, strong in prototyping, good hygiene, etc., but moisture-proof sexuality, the permeability of the oil and gas barrier gas is poor, and plastic packaging materials have excellent Moisture-proof, oil resistance, better barrier gas, is not easy to decompose, therefore, the two materials are used in conjunction with the use. And paper is the main raw material, unlimited development of paper packaging materials, a large number of forests, will cause serious damage to the natural environment, affect ecological balance, so paper plastic is completely standing. In summary, we believe that as a new type of material in modern scientific achievements, plastic packaging materials are superior performance, easy to use, low cost, cost-effective, have many other traditional packaging materials. Many Advantages, some problems in use will be overcome with people's understanding of the degree of understanding and the continuous development of science and technology, thereby gaining greater development in new heights.
Between plastic packaging materials and conventional packaging materials, in some specific applications, there may be mutual conversion, mutual replacement, and there is a situation in which each other is compained in a quite long period.
