Analysis of the development status of plastic packaging machinery industry at home and abroad

[China Packaging News] China's modern packaging industry has developed rapidly since the implementation of the reform and opening-up policy. After three decades of development, China's packaging industry has become an independent, complete and comprehensive industrial system with paper, plastic, metal, glass, packaging printing and packaging machinery and equipment as the main industries, and a packaging industry pattern with the Yangtze River Delta, Pearl River Delta and Bohai Bay as the key areas

packaging plastic consumption is the largest variety in plastic consumption, with diverse styles and rapid technological updates. At the same time, with the development of packaging plastic consumption, the plastic packaging machinery industry has a good prospect, and the domestic and foreign market potential is huge

in the world's plastic industry, the largest consumption is packaging plastic, which generally accounts for 25% - 70% of the total consumption of plastic. Taking the United States, Japan and Germany, which have the most developed plastic industry, for example, packaging plastic accounts for 27.2%, 32.8% and 27.2% of the total consumption of plastic, while plastic packaging accounts for about 25% of the total consumption of plastic in China

development prospect of international plastic packaging materials

1 Plastic packaging has become one of the materials with the fastest demand growth in the packaging industry

internationally, although plastic packaging materials have been subjected to serious challenges from environmental problems, it is hoped that several products published in recent years are exported to more than 20 countries and regions. It is seen that plastic packaging still becomes one of the materials with the fastest demand growth in the packaging industry. The annual average growth rate of paper and plastic in the packaging field in the United States is 2.4%, of which plastic is 3.4%, and the sales volume of plastic packaging materials in Japan accounts for 15.4% of the total sales volume of all kinds of packaging, ranking second

2. High barrier and multi-functional plastic packaging materials have become the focus of many countries to develop packaging materials

such materials include high impermeability, multi-functional freshness preservation, selection of permeability, heat resistance, sterility (antibacterial), changing the experimental machine with springs, and plastic packaging materials such as rust prevention, deodorization, shape memory, resealability, easy unsealing, among which the development of high barrier and permeability multi-functional freshness preservation, sterile packaging materials is more rapid, It will become the focus of development at the beginning of the 21st century

3. Energy saving, environmental protection and easy recycling have become the starting point of technological development.

the 21st century is an environmental protection century. Plastic packaging materials will usher in new opportunities and face severe challenges. In order to meet the requirements of the new era, plastic packaging materials are required to meet the increasing requirements of market packaging quality and efficiency, but also to further save energy and pay attention to recycling

4. The development of antistatic and conductive flexible plastic packaging materials has broad development prospects

5 Plastic blends, plastic alloys, inorganic materials filled and reinforced composites (ABC) will become the star of plastics in the future

development trend of domestic plastic packaging materials

1 At present, high-tech equipment should be introduced, special polyester films should be developed, and heat sealing films should be produced through multi-layer coextrusion technology to occupy the fresh-keeping food and frozen food packaging market; At the same time, the technology suitable for the production of heat shrinkable film is introduced, and the film for polyester bottle label is developed

2. The high barrier and multifunctional film is developing to a new technical level

the original composite film is developing to a deeper level, and the bag making and printing technology has reached a new level, accelerating the pace of entering the color revolution. At the same time, the whole industry has adopted offset, gravure and flexographic color systems, which has promoted the in-depth development of flexible plastic packaging materials. The anti-counterfeiting packaging film is developing with each passing day, which is known as the flower of flexible plastic packaging

3. The development of multi-layer coextrusion technology has changed the product structure of functional films and containers and adapted to the market demand

with the development of market economy, higher requirements have been put forward for the packaging of daily necessities, cosmetics, food and household appliances. On the one hand, with the increasing voice of environmental protection, how to reduce the amount of garbage as much as possible on the premise of meeting the packaging functionality, so as to show that the packaging film and packaging container are developing in the direction of lightweight and thin-walled. The high barrier film mainly based on dry compounding, the use of adhesives and solvents in the production process can easily pollute the environment, and the development of CO extrusion packaging film has the advantages of low investment in process equipment, low cost, strong adaptability Easy to operate. Coextrusion technology has developed rapidly in the world. Relevant data show that coextrusion packaging film in developed countries accounts for 40% of the whole flexible plastic packaging materials, while we only account for 6%. It is still mainly dry composite film, and the strain at a certain point of two elastic elements ε The proportion that is proportional to the force on the elastic element is unreasonable

4. The market prospect of fresh-keeping packaging film for vegetables and fruits is broad.

China is the largest country in the production and sales of fruits and vegetables in the world. However, about 30% of 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 becoming more and more important. At present, polyethylene film and polypropylene film are the most widely used packaging materials for fresh fruits and vegetables

5. Attractive business opportunities lie in the plastic beverage bottle Market

Plastic packaging containers have a broad application market, among which there are attractive business opportunities in the beverage industry. The demand for plastic containers for soda, fruit juice, vegetables and beverages is increasing day by day. The application proportion of PET bottles in carbonated beverage packaging accounts for 57.4%, and the market prospect is promising

with the sudden rise of the domestic tea beverage market, hot filled PET bottles have become the fastest-growing variety of polyester bottles, with an annual growth rate of more than 50% The development of polypropylene transparent packaging bottles has become a hot spot in plastic packaging at home and abroad in recent years. High transparent PP can be widely used in injection, extrusion, blow drawing, extrusion, hot containers, food, medicine bottles, etc. its price is appropriate. It is a competitor of PS, ABS, pet, PE bottles, and has a broad market prospect

6. The market of drinking water packaging bottles (barrels)

the national bottled aquatic product volume is 5.54 million tons, accounting for nearly 1/4 of the total beverage volume, and has entered thousands of households. At present, it is urgent to develop food grade PC raw materials. Shanghai and Bayer have signed a contract to build 100000 ton PC resin. The first phase was put into operation in 2003, with an annual output of 50000 tons, which can alleviate the long-term situation of importing PC

7. It is predicted that the market demand for heat shrinkable film will increase by 20% in the next five years, especially the application of pet heat shrinkable film on PET beer bottles, which reduces the process of removing labels and is very conducive to the recycling of bottles

Europe and the United States are the most developed countries in the plastic packaging industry in the world. It is very important to install two chucks. It is necessary to develop and develop advanced packaging machinery. According to Luo Baihui, Secretary General of the International Association of mold, hardware and plastic industry suppliers, European and American countries have a wide variety of packaging machinery and advanced equipment, but in order to adapt to the competition in the international market, they are still constantly developing more advanced plastic packaging machinery and equipment

under such a situation, Chinese packaging machinery industry enterprises should adhere to the "going out" development strategy and actively expand foreign markets. Luo Baihui pointed out that domestic packaging machinery industry enterprises should take offensive operations, actively participate in the cooperation and merger between international enterprises in the same industry or even across industries, digest and absorb their advanced technology through overseas investment and acquisition of foreign enterprises, and realize nationalization as soon as possible, so as to enhance the international status of China's packaging machinery industry
