Jiangyin Shenda Group and Zhejiang Dadongnan Plastic Group, which have reached more than 1 billion yuan from thousands of yuan, have become well-known large-scale packaging private enterprises at home and abroad after fighting in the market economy; the original small and medium-sized plastic packaging enterprises have undergone adjustment structure. Asset restructuring and technological transformation have also gained vitality. Foshan Oriental Packaging Materials Co., Ltd. and Foshan DuPont Hongji Packaging Materials Co., Ltd. play an important role in the industry with a new look.
The economic performance of the plastic packaging industry was good in 2003.
1. Scale and technological innovation promote the development of soft plastic film
Soft plastic film presents a trend of scale development. Biaxially stretched film grows fast. On the one hand, BOPP special materials have been produced by six companies in China, accounting for 50% of total demand (including Shanghai Petrochemical, Beijing Yanhua, Qilu Petrochemical, Maoming Petrochemical, Guangzhou Petrochemical, Jiujiang Petrochemical). The requirement of pulling film speed of 350-400m/min reduces the dependence on foreign countries; on the other hand, the newly added production line has been put into production in 2003 with a new capacity of more than 100,000 tons.
Capital is combined with regional advantages. Wenzhou's Mao Fang lead and Wu Changshuo investors, looking at the northern market, set up Deli Company in Lingxian County, Shandong Province, and introduced an annual production capacity of 15,000 tons of BOPP production line. It was introduced in 2001. In 2003, the output value reached 220 million yuan and the annual tax reached 60 million. yuan.
Innovation has become the driving force behind the development of plastic packaging. The high-performance molecular assembly antibacterial film produced by Guangdong Yuankun Company and Yuankun Packaging Co., Ltd. will be put on the market and has a gratifying step in innovation; the laser anti-counterfeiting film of Shanghai Zijiang Color Printing Co., Ltd. and the gas-permeable cast film of Yuankun Company , Wisteria's antistatic cast polypropylene film is included in the torch project; Nanjing Zhongda co-extruded heat-sealed biaxially oriented polypropylene film to maintain the thermal shrinkage of BOPP, while solving the problem of heat sealability and cigarette film packaging The problem of adhesion between the middle strip film and the small strip film is solved, and the hole sealing technology is adopted to solve the problem of BOPP heat sealability. In short, innovation has become the driving force behind the development of plastic packaging.
2. The woven industry overcomes various difficulties and achieves gratifying results.
Plastic weaving and blow molding, compounding, color printing, plate making and other supporting processes, simultaneous development, improved competitiveness in the international market, increased export volume, and effectively occupied the Asian-American market.
The rapid development of plastic weaving machinery has promoted the development of woven products. Since 2003, the technical level of plastic wire drawing machines, circular looms and supporting equipment have been improved to varying degrees, and a number of new products have emerged. A new type of coated film woven plastic bag joint unit has been introduced. The unit combines six processes of composite, automatic cutting waste, automatic punching, multi-color printing on the front and back, shifting and folding and seven-word cutting technology. Save labor and materials, reduce costs and improve quality. On the other hand, more export machinery companies have increased their exports to the international market. They have exported to the developing countries such as the Philippines, Peru, and Jordan, and then exported to South Korea, Brazil, and Europe and the United States. The prospects are promising. Zhejiang Yanfeng Plastic Machinery Factory has exported small four shuttle circular looms in batches, which is expected to reach US$2 million this year. The drum type small six shuttle circular loom of Wenzhou Hengyi Plastic Machinery Co., Ltd. has been adopted by American plastic knitting enterprises.
Asset restructuring has enabled the company to continue to grow and develop. Mr. Ye Qile from Wenzhou woven company went to Sichuan for development and occupied the woven bag packaging market required by Feed Group. It is a far-sighted approach. In 1995, he built Jinlu Packaging Company in Xinjin County; in 1998, he established a joint venture with Sichuan Hope Agriculture Company to build Xinle Plastics Co., Ltd.; in 2000, he built Qile Plastics Group; in 2002, he invested 100 million yuan to enable enterprises to have 600 plastic knitting machines. The output value reached 300 million yuan. This year, together with Zhejiang Longxinglong Industrial Co., Ltd., a group of more than 40 plastic knitting enterprises will form a plastic-weaving enterprise group. It is expected that the output value will reach 800 million yuan within two or three years after the project is put into production. .
Rapid production of plastic packaging containers (barrels, bottles, boxes)
The annual output of plastic packaging containers (barrels, bottles, boxes) reached 730,000 tons. Among more than 600 enterprises, 24 were over 5,000 tons, 4 were over 10,000 tons, and 95,800 tons of Zijiang Group, accounting for 15%. The first in the country, Hebei Xingtai Jin County, 29,400 tons, accounting for 3.2%, Zhongfu 13,500, followed by Sanshui Jianlibao, Dongguan Yihuang and so on.
1. Plastic film polyethylene film: including low density polyethylene film (LDPE), high density polyethylene film (HDPE), linear low density polyethylene film (LLDPE). It is a large amount of plastic film, accounting for more than 30% of the total film consumption. Although it is not ideal in terms of appearance and strength, it has good toughness, moisture resistance and heat sealing performance, easy processing and moderate price. So the application is very extensive. EDM or corona treatment is required before printing.
Polypropylene film: unstretched film and biaxially stretched film. Unstretched film has better transparency, gloss, moisture resistance, heat resistance and oil resistance than PE; mechanical strength, tear resistance, Good puncture resistance and wear resistance; non-toxic and odorless. Therefore, it is widely used in the packaging of food, pharmaceuticals, textiles and other items. However, it has poor cold resistance and is brittle at 0-10 ° C. It cannot be used for the packaging of frozen foods. It has high heat resistance and good heat sealing properties, so it is often used for the heat seal layer of the retort pouch.
Polyvinyl chloride film (PVC): soft film and hard film, soft film elongation, tear strength and cold resistance is good, easy to print and heat seal, can be made into a transparent film. Since the soft PVC film has the odor of plasticizer and the problem of plasticizer migrating, it is generally not used for food packaging. However, it can be used to package foods by the internal plasticization method. Generally used mainly in industrial products and non-food packaging; hard film does not contain plasticizer or plasticizer content, film is stiff, toughness, kinks stable, good air tightness, fragrance retention and better Moisture resistance, excellent printing performance, can produce non-toxic film mainly used for twisting and packaging of candy, packaging of textiles, clothing and packaging of cigarettes and food packaging, but cold resistance is poor, brittle at low temperature, it is not suitable As a frozen food packaging material.
a, polystyrene film: rarely used as flexible packaging materials
b. Polyvinylidene chloride film (PVDC): It is a flexible, transparent, high barrier film. It has moisture resistance, air tightness and aroma retention, and has excellent resistance to strong acids, alkalis, chemicals and oil. Currently used mainly for the production of composite films, it is suitable for heat shrink packaging of sausages, ham and other meat products.
