The main problems of plastic packaging materials

1. Unreasonable product structure The plastic packaging material is mainly made of film, but the variety of packaging films is unreasonable. The current introduction of biaxially stretched film is more serious, and the proportion of co-extruded film is less; in terms of variety, EVA, EVOH, Functional films such as BOPA and PVA are under development.
2. The overall level of technical equipment is backward, the scale of operations is small, and the number of medium and low-end products is high.
In the past 20 years, the plastic packaging materials industry has introduced a large number of technical equipment from abroad and has a number of foreign-funded enterprises. Domestic plastic processing equipment has improved significantly in variety and quality, but throughout the industry, the level of technical equipment is still low.
The production of large turnover containers and pallets required more than 30,000 grams of injection machines and large-scale complex molds are almost all dependent on imports. The two-way stretching production line is also a full set of imports. The domestic digestion and absorption capacity is very poor, and most of the product accessories also rely on imports.
In addition, the scale of the company is small, the product technology is low, the situation of repeated product production is severe, and the enterprise management is poor. The company has few scientific and technological inputs, weak development capabilities, and research and development of its own research process, which exceeds the international advanced level.
3. The development is unbalanced. The gap between the southeast coast and the western region is continuously expanding the production of plastic packaging materials. The output of Guangdong, Zhejiang, Shandong, Jiangsu, and Shanghai accounts for more than 50%, of which only two-way stretching films account for 60 percent of Guangdong Province. %the above.
4. The contradiction between recycling and management of plastic packaging waste and recycling technology and social environmental protection are prominent.
With the increase of plastic packaging waste, especially disposable packaging materials and foam lunch boxes, it has become a major problem for urban and rural environmental governance. There is still a lack of perfect methods for the management of waste recycling, and re-use technology is still at a stage of development. It is not yet fully mature. Therefore, scientific treatment of this problem has become an important issue for the production and development of plastic packaging enterprises.
