Plastic packaging has not only become one of the main packaging materials in the field of consumer goods, but also the scope of application has gradually expanded to major production areas and transportation packaging fields. According to a research report by the Freedonia market consulting company in the United States, the fastest growing areas of plastic packaging are beverages and pet foods, followed by confectionery, baked goods and frozen foods, as well as the detergent market and industrial packaging; in a European research report , It is also the largest use of food and beverage plastic packaging.
If the current plastic packaging products are roughly classified, they can be divided into three main categories: plastic films, plastic bottles (containers), and industrial plastic packaging.
Plastic film is not only an indispensable raw material in the packaging industry, but also an indispensable raw material in the production of many other industries. As one of the four major packaging materials, its position in the packaging industry is no different from that of paper. Plastic film occupies a large part of the packaging material market with its excellent "cost-effective" advantage, mainly because it has obvious "irreplaceability".
The advantages and disadvantages of a single plastic film material are both very obvious. However, with the application of composite technology and new catalysts, more and more new materials and different composite materials forming multilayer plastic film materials have been developed and widely used. Greatly changed the development of the traditional plastic film industry. New grades of polyolefin materials that have been developed at home and abroad include: metallocene PE, ultra-low density polyethylene MULDPE, special elastomer PE, hexene-1 (C6) and octene-1 (C8) LLDPE copolymers, metallocene Innovative LLDPE resin, cyclic olefin copolymer (COC), metallocene PP, high-strength and high-transparency MPP, high-melt-strength polypropylene (HMSPP), etc. combined with catalyst technology and bimodal technology.
Although plastic bottles (containers) face the impact of paper-plastic composite packaging, glass bottles, and metal cans in the field of dairy products and beverages, they still dominate the market, especially in the detergent market where plastic containers are almost the world. With the research and development of PET bottle processing and manufacturing technology, the beer bottle market and the dairy product market have begun to reversely "aggress". Although these new technology hotspots have just started, they are about to become the new favorites of the market.
Industrial plastic packaging is mainly used to replace the traditional transportation material market. On the one hand, with its excellent recyclable characteristics, it continuously replaces the disposable paper packaging materials in the original industrial system. This is also due to the entire industrial system. The continuous market segmentation, the increasing focus of the processing and manufacturing industry, and the increasing vertical depth have resulted in a multi-point, directional, and complementary parts transportation form, and has also given birth to the conditions for the use of new circular packaging, especially in auto parts The industry has also begun to gradually penetrate into industrial fields such as communication equipment, electronic appliances and so on. On the other hand, the original blister packaging materials commonly used in toys and small electronics industries have also begun to advance to the cosmetic packaging field with the application of new materials and the deepening and improvement of processing and manufacturing techniques, gradually playing the role of replacing some paper packaging. .
From this point of view, plastic packaging materials should be more aggressive. However, the performance of plastic packaging materials has also caused plastic packaging materials to face shortages of energy resources on which they depend, and environmental impacts, including the impact on plastic materials. Prejudice issues, these are the challenges that the plastic packaging industry needs to face. In the face of these challenges, if the plastic industry is environmentally sustainable, plastic packaging is reduced in weight and weight, and plastic product processing and manufacturing is lean and automated, it should be able to solve the dilemma faced by the plastic packaging industry.
Environmental sustainability is to make the manufacturing and processing of plastic packaging materials more sustainable and environmentally friendly, and truly reduce the harm to the environment. This is not just a simple method of reducing the amount of plastic packaging materials, but also the whole need to save energy and consumption, adopt cleaner production, reduce waste production, increase recycling, and increase degradation or recycling mechanisms from the source of manufacturing. The establishment and improvement of the system. In fact, this is the most important point, but to solve this problem, the following two points must be properly resolved.
Reduce weight and weight, simple understanding is to use less plastic materials as much as possible on the premise of ensuring the performance and use effect of plastic packaging, so that the weight of plastic packaging products can be reduced. The research and development of new material grades and high-performance and multifunctional materials has made weight reduction and weight reduction increasingly feasible. Even if the total economic volume of the plastic packaging industry declines to a certain extent, this economic value is higher. This is the direction of China's packaging industry to strive for excellence. The lean and automation of plastic products processing and manufacturing is to properly implement the three requirements of energy saving and consumption saving, adopting cleaner production, and reducing waste production from the manufacturing source. At the same time, it can fully solve the problem of overcapacity in the existing plastic packaging industry, and can further consolidate the internal strength of the plastic packaging manufacturing industry. Only in the future can it be made into a "true sense of China's intelligent manufacturing".
