3. Energy-saving, environmental protection, and easy recycling become the starting point for technological development
The 21st century is the century of environmental protection. Plastic packaging materials will usher in new opportunities and will also face severe challenges. In order to meet the requirements of the new era, plastic packaging materials, in addition to meeting the ever-increasing requirements of market packaging quality and efficiency, are also required. Need to further save energy, and pay attention to recycling.
4. Develop anti-static and conductive soft plastic packaging materials with broad prospects for development
5. Plastic blends, plastic alloys, and inorganic materials filled with reinforced composites (ABC) will become plastic stars of tomorrow.
Domestic plastic packaging materials development trend
1. Rapid development of biaxially oriented films on composite substrates
At present, high-tech equipment should be introduced, special polyester films should be developed, heat-sealable films should be produced through multi-layer co-extrusion process technology, and occupy the market of fresh food and frozen food packaging; at the same time, polyester should be introduced to meet the production of heat-shrinkable film technology. Labels for bottles, etc.
2. High barrier, versatile films are moving to new levels of technology
The original composite film is developing to a deeper level and the bag making and printing technologies have reached a new level, accelerating the pace of entering the color revolution. At the same time, the entire industry has been a monthly version of offset, gravure, flexo color system, to promote the development of soft plastic packaging materials to the depth of anti-counterfeiting packaging film is changing with each passing day, known as the soft plastic packaging of the normally open flower.
3. The development of multi-layer co-extrusion technology has changed the product structure of functional films and containers and adapted to market demands.
With the development of the market economy, daily goods packaging, cosmetics packaging, food packaging, and household appliance packaging have all put forward higher requirements. On the one hand, with the rising demand for environmental protection, how to reduce the amount of waste generated under the premise of satisfying the packaging functionality, and to develop the direction of lightweight and thin-walled packaging film and packaging containers, and to dry compound The main high-barrier films use adhesives and solvents to facilitate the environment pollution during the production process, while the development of co-extrusion packaging films, the process equipment investment, low cost, adaptability, and easy operation. International co-extrusion technology has developed rapidly. Relevant information shows that co-extruded packaging films in developed countries account for 40% of the total flexible plastic packaging materials, while we account for only 6%, still based on dry-laid composite films, and their ratio is unreasonable. .
4. Fruit and vegetable fresh-keeping packaging film has a promising market
China is the world’s largest producer and seller of fruit and vegetables. However, about 30% of the fruits are lost in the process of storage, transportation, and sales. Among them, improper packaging is an important reason. In the highly competitive market conditions, the role of packaging is increasingly important. At present, polyethylene film and polypropylene film are the most widely used packaging materials for fresh fruits and vegetables.
5. The plastic beverage bottle market lurks attractive business opportunities
Plastic packaging containers have a wide application market, of which the beverage industry has attractive business opportunities, and the demand for plastic containers for soft drinks, juices, vegetables, and beverages is increasing day by day. The proportion of PET bottles used in carbonated beverages accounted for 57.4%, and the market prospects are promising.
With the sudden emergence of the domestic tea beverage market, hot-filled PET bottles have become the fastest growing varieties of polyester bottles. The annual growth rate exceeds 50%. The development of polypropylene transparent packaging bottles is a hot spot for plastic packaging at home and abroad in recent years. Among them, high transparent PP can be widely used in injection, blowing, blowing, extrusion, hot containers, food, medicine bottles, etc., and its price is appropriate. It is a competitor of PS, ABS, PET, and PE bottles and has a broad market. prospect.
6. The market for drinking water bottles (barrels)
The national bottled water production was 5.54 million tons, accounting for nearly 1/4 of the total amount of beverages, and it has entered thousands of households. The current development of food-grade PC raw materials is very urgent. Shanghai and Bayer have signed contracts for the construction of 100,000-ton grade PC resin, which will be put into production in the first period of 2003 with an annual output of 50,000 tons, which can ease the long-term dependence on imports of PCs.
7. The heat shrink film develops in the direction of multi-function, and the market prospect is promising
It is predicted that the market demand for heat-shrinkable films will increase at a rate of 20% in the next five years. In particular, the application of PET heat-shrinkable films on PET beer bottles will reduce the number of labels removed, which is very beneficial to the recycling of bottles. .
Europe and the United States are the most developed countries in the plastic packaging industry in the world. They attach great importance to the research and development of advanced packaging machinery. According to Luo Baihui, secretary-general of the International Mould and Hardware and Plastics Industry Suppliers Association, European and American countries have a wide variety of packaging machines and advanced equipment. However, in order to be able to adapt to the competition in the international market, they are still developing and developing more advanced plastic packaging machinery and equipment.
Under such circumstances, enterprises in the packaging machinery industry in China should adhere to the "going out" development strategy and actively expand foreign markets. Luo Baihui pointed out that enterprises in the domestic packaging machinery industry should take offensive operations and actively participate in the cooperation and merger between international companies and even cross-industry companies. Through overseas investment, acquisition of foreign companies, their advanced technologies will be absorbed and quickly realized. Localization, and thus improve the international status of China's packaging machinery industry.
