The market and technical progress of food packaging plastics at home and abroad

I. the progress of plastic food packaging market abroad

according to the food packaging container survey conducted by a market research company in the United States, the annual growth rate of paper containers, metal containers, glass containers and plastic containers has been 3.2%, 2.5%, 0.5% and 5.5% respectively in the past five years

according to the data, the amount of plastic used for food packaging accounts for 1/4 of the total plastic output. In supermarkets and shopping malls, many food packages are made of plastic. The plastic inflatable packaging of puffed food can prevent moisture, oxidation, fragrance, sunlight and extrusion, but such a large packaging is a great waste of resources; There is also the packaging of instant noodles. Plastic packaging is far more than that of paper bowls (or barrels). The sales price of bowls or barrels of instant noodles in the market is generally 1/3 higher than that of packaged instant noodles of the same quality. Because this packaging method is convenient to eat, especially when traveling, it can be eaten directly by boiling bubbles after opening the lid. 1 there is no need to bring other containers, so it is very popular with consumers

the latest market forecast report shows that the consumption of plastic packaging for food and beverage in Europe has increased in recent years and the next few years. By 2007, the market sales of plastic packaging for food and beverage in Europe will increase from $4.91 billion in 2000 to $7.15 billion, with an average annual growth rate of 5.5%. Analysis of insiders: the fastest growth rate of plastic packaging sales of food and beverage in the European market will be the PP packaging market, in which the average growth rate of thermoplastic PP will reach 10.7%, transparent PP will increase by 9.5%, followed by pet, with an average annual growth rate of about 9.2%, while the growth rate of foamed PS and soft PVC market is the smallest, and may even stop growing. France (18.7%) is the country that uses the most plastic packaging materials in the food and beverage industry in Europe, followed by Italy (18%) and Germany (17.2%). With the improvement of people's living standards, new packaging technologies, products and materials continue to emerge

at present, the new food packaging popular in the U.S. market is mostly plastic packaging, which mainly includes high-temperature sterilization plastic cans, high barrier material food packaging, sterile packaging, flexible packaging materials and container packaging

the research report released by the consulting company of Freedonia group predicts that by 2008, the growth rate of plastic packaging will exceed that of paper packaging, and its growth rate will exceed 3%. It is expected that the fastest growing market share of plastic packaging will include pet food, fruit juice drinks, eggs, candy and baked goods packaging. The report also pointed out that due to the development of the flexible packaging market, its consumption has increased, and plastic packaging is easy to process and recyclable, so its market competitiveness is significantly greater than that of paper products. In 2006, the plastic consumption in the U.S. packaging market will exceed that of paper in 17 market segments, reaching 4.9 million tons. The forecast shows that the annual growth rate of the plastic beverage container market in the United States in 2008 can reach 4.8%, and the growth rate of the plastic bottle Market for food purposes can reach 4.9%. By 2008, the market application of candy packaging, beverage packaging, fast food packaging and snack packaging bags will be further expanded. With the expansion of the application field of metal coating and high barrier composite film, the market demand in this area will also grow. In 2008, the market share of plastics in packaging is expected to increase to about 50%. However, as many markets controlled by plastics are quite mature at present, the market share of plastics will expand at a relatively slow rate compared with the past decade. Nevertheless, the improvement of plastic properties will continue to stimulate the development of plastic packaging market, which will extend the shelf life of goods, reduce the use of materials and make packaging more convenient. Before 2008, HDPE will continue to be the main plastic container resin, but it will be replaced by PET by 2013

among the top ten development directions of food packaging in the United States, five are mainly plastic packaging, the first of which is: for most new packaging, raw materials based on petrochemical products are mainly used; The third is that plastic cans and bottles will replace glass products and metal products in some cases. At the same time, packaging costs will be reduced by improving the performance of packaging materials, rather than unilaterally pursuing price reduction; Light packaging will continue to make progress; Promotion of filling packaging, etc. It can be seen from this that the development prospect of plastic packaging in the food industry is very broad

according to the data provided by the Research Report "rigid food packaging", a new topic 1, which is published by business communication company, Inc. (BCC), which specializes in industrial research and market analysis in Norwalk, Connecticut, the United States. It can achieve a stable constant loading rate. In 2004, the total consumption of plastic hard packaging for food in North America reached 4.673 million tons, which is expected to exceed 6.18 million tons in 2008, During this period, the average annual growth rate (AAGR) was 5.8%. Food hard packaging "containers" are composed of the following products with different structures: bottles, boxes, cans, covered barrels, etc., which are relatively easy to distinguish. Other containers include frozen, low-temperature food packaging and room temperature food packaging with different shapes and thicknesses, which are suitable for reheating requirements of microwave ovens, mainly hard plastic and foamed plastic products. Hard packaging molding methods include injection molding, blow molding (hollow molding) and thermal molding. The food plastic hard packaging market also includes supplies for the food service industry, such as bowls, cups, plates, covers, plugs and covers. The main products of plastic hard packaging of food are all kinds of beverage bottles, milk bottles, meat containers, cooked food packaging (frozen and reheated in microwave oven). At present, the largest amount of plastic hard packaging for food is still bottles, the main raw material is pet, followed by blow molded containers for liquid food packaging, with pet and HDPE as the main resins. Another important market is thermoplastic PS and PP containers

in the beverage market, plastic bottles, especially PET bottles, are the most important and eye-catching packaging. In the carbonated beverage, water and beer markets, there is no paper packaging market at all; In the fruit juice market, compared with plastic containers, paper composite containers have a relatively close market share; PET bottles have appeared in the Baijiu market. For example, pet plastic bottles have been used in all Jianzhuang liquor produced by Wuliangye Group. Plastic beer bottles are also under intensive development, and products have been launched in the United States and Europe. Plastic bags of soy sauce have also appeared, and plastic barrels of soy sauce and vinegar have broken the dominance of glass bottles. Small packages such as monosodium glutamate and pepper powder are basically the market of plastic bags, and paper packaging is rarely used

II. Market progress of domestic plastic food packaging

the plastic packaging industry has become one of the fastest growing fields in China's plastic industry. In 2004, the output of plastic packaging products reached 634.13 million tons, a year-on-year increase of 1513%; The output value reached 92billion yuan, accounting for 28% of the total output value of the packaging industry. In 2004, the export volume of plastic packaging products reached million tons, and the import volume was 160.194 million tons; Plastic packaging products export 12517.6 billion US dollars and import 6614.7 billion US dollars. The top three provinces in the output of plastic packaging products are Guangdong, Zhejiang and Jiangsu, accounting for 26%, 21% and 11% respectively. It is estimated that China's packaging plastics will reach 7million tons in 2005

1. Food can be equipped with various friction pairs. The main form of plastic used for chuck packaging

according to the prediction of China's authoritative departments, the sales volume of plastic flexible packaging in the food industry will exceed nearly 50% of the sales volume of the packaging industry in the next two years. It is expected that the overall development speed of flexible packaging will be slightly faster than that of the overall national products. Due to the excellent impermeability, UV linearity, freezing resistance and heat resistance of the improved plastic materials, the application market is broad, especially in the beverage and dairy industry. The application of plastics in aseptic packaging provides a development space for plastic packaging materials. At the same time, the improvement of plastic packaging materials will also promote the development of aseptic packaging in China

the output of plastic packaging containers (barrels, bottles, boxes) reached 1.1 million tons in 2004. Among more than 600 enterprises, 24 enterprises with an annual output of more than 5000 tons and 4 enterprises with an annual output of more than 10000 tons after the creation of bottle blanks. Among them, Zijiang group has 91.58 million tons, accounting for 817%, ranking first in the country; Jin county, Xingtai, Hebei Province, 21.94 million tons, accounting for 217%; Zhongfu 11.35 million tons, followed by Sanshui Jianlibao, Dongguan Yihuang, etc

high barrier and multi-functional flexible plastic packaging materials have become the focus of domestic development in recent years, and a number of new products and new technologies have emerged, including high impermeability, multi-functional fresh-keeping film, sterile packaging film and so on; The original composite film is developing to a deeper level. Bag making and printing technology have reached a new level and entered the era of "Color Revolution". There are offset, gravure and flexographic color systems in the industry, which has promoted the development of flexible plastic packaging products to a deeper and higher level

the demand for plastic film in the domestic market will continue to grow at a rate of 9% per year, and the market prospect of plastic film in China is very broad. At present, the output of plastic film accounts for about 40% of the total output of plastic products in China, which is the fastest growing output in the plastic products industry. There are more than 2240 plastic film production enterprises in China, including 65 enterprises with an output of more than 5000 tons, 25 enterprises with an output of more than 10000 tons and 5 enterprises with an output of more than 50000 tons. The synthetic resins used in the production of plastic films in China mainly include polypropylene, polyvinyl chloride, polyethylene and polyester. The processing methods are blow molding, biaxial stretching, tape casting, etc. About 2/3 of the plastic film market is used as packaging materials. The mainstream products in the market are domestic PE fresh-keeping film and PVDC fresh-keeping film. The controversial PVC fresh-keeping film is mainly used to pack fresh fruits and vegetables in some supermarkets. Domestic PVC fresh-keeping film brands are mainly LG, Mitsubishi and Sanrong. The three brands account for 70% to 80% of the whole market, while Japanese and Korean products account for more than 80% of the whole market. Most household food preservative films sold in the domestic market are made of safe polyethylene (PE) and polyvinylidene chloride (PVDC) materials

some experts pointed out that PVDC film will gradually become the mainstream material of food packaging in China. In addition to the general properties of plastics, PVDC also has excellent self extinguishing, oil resistance, flavor retention, moisture and mildew resistance. At the same time, it also has excellent printing and heat sealing properties, which are widely used by food manufacturers. Among the current types of meat products in China, ham sausage products occupy a large market because of its long shelf life and easy to carry. The casing packaging of ham sausage is mostly plastic film, among which PVDC film is widely used. Compared with ordinary PE film, paper, aluminum foil and other packaging materials, the amount of composite packaging using PVDC is much reduced, so as to achieve the purpose of reducing packaging and waste sources. In the United States, PVDC products are non-toxic and safe plastic materials, which have been widely used in food packaging; In Germany, PVDC packaging materials have green marks; About 60% of the small packaged food, drugs, chemical products and electronic products circulating in the markets of Japan and South Korea are packaged with PVDC. With the popularity of this new packaging material, the output of PVDC resin in western countries has increased year by year, with an annual growth rate of 2% in the United States and nearly 10% in Japan. In view of the current situation that the level of food packaging in China is still relatively backward, experts pointed out that the promotion and use of PVDC materials can not only improve the grade of packaging products in China, but also reduce the losses caused by product packaging, so as to enhance market competitiveness and establish a new image of enterprises. It can be predicted that P will be fully and reasonably used in food packaging in the future
