Plastic packaging pays attention to technology and ushers in business opportunities

according to Cai Mingchi, Secretary General of the plastic packaging Committee of the China Packaging Technology Association, since this year, the plastic packaging industry has got rid of the impact of SARS, adhered to technological innovation, and continued to maintain the development trend of stable growth, with good development opportunities

according to relevant statistics, plastic raw materials are expected to increase by 16%, plastic products by 15.8% and export delivery value by 21% this year. The output of plastic packaging materials is expected to reach 4.6 million tons, an increase of 15% over last year's 4.01 million tons, of which biaxial tensile film, soft plastic composite packaging materials and packaging containers (bottles, boxes, barrels) increased significantly

biaxially oriented films grow fastest. On the one hand, BOPP special materials have been produced by six domestic enterprises, including Shanghai Petrochemical and Beijing Yanhua, accounting for 50% of the total demand; On the other hand, the introduced production lines have been put into operation this year, and the newly increased capacity is more than 100000 tons. For example, Sichuan Zhongda company and Jiangsu Shuangliang group have introduced large-scale production lines respectively, which are now under construction. Innovation has become the driving force for the development of plastic packaging

high barrier and multifunctional flexible plastic packaging materials have become a hot spot in recent years. High permeability, multifunctional fresh-keeping film and sterile packaging film are developing rapidly. The original composite film is developing to a deeper level, and the bag making and printing technology has reached a new level. There are offset, gravure and flexographic color printing systems in the whole industry, which has promoted the in-depth development of soft plastic packaging materials; Anti counterfeit packaging film is becoming a common flower of soft plastic packaging

coextrusion technology has also made new progress. At present, in addition to the stacking head technology of Dalian Liaonan Dongfang Machinery Co., Ltd., the domestic coextrusion blow molding technology and equipment have passed the product identification and began mass production. The five layer co extrusion barrier film blow molding machine, which was opened by Guangdong Jinming plastic equipment company and can be freely transformed as needed in the experimental process, has passed the new product appraisal. The development of CO extrusion packaging film will change the product structure of multi-functional film, which is suitable for the packaging of liquid food, milk, fresh meat and other food

vegetable and fruit fresh-keeping packaging film has a broad market prospect. According to Mr. caimingchi, China is the world's largest fruit and vegetable production and sales country. However, about 30% of the fruits are lost in the process of storage, transportation and sales. Among them, improper packaging is one of the reasons for the fruit decay loss, from the cathode to the battery cell to the vehicle system to the echelon utilization and then to the recycling of raw materials. Although the physiological properties of different fruits are different, and it is required to reach 2020, discoloration, dehydration, flavor change and decay are common problems. Therefore, how to inhibit the metabolic process, reduce the consumption of nutrients, and maintain the flavor quality of fruits is an important topic of reliability technology, especially in some military, aerospace, electric power, nuclear industry facilities. At present, polyethylene film and polypropylene film are the most widely used packaging materials for fresh fruits and vegetables

attractive business opportunities lurk in the plastic beverage bottle market. After investigation, the application proportion of PET bottles in carbonated beverage packaging in China accounts for 57.4%, and the market prospect is promising. PET bottles started relatively late in the plastic packaging industry. The introduction of a large number of injection and drawing technology and equipment has promoted the large-scale production of PET bottles. In just a few years, PET bottles have become the mainstream packaging materials for beverage bottles with their excellent performance. Among them, hot filled 85 ℃ -90 ℃ PET bottles have become the fastest growing variety of polyester bottles, with an annual growth rate of more than 50%. At present, the enterprises with large PET bottle output in the industry include Zhuhai Zhongfu company and Shanghai Zijiang group, accounting for 30% and 40% market shares respectively

the heat-resistant polyester bottle (PET) used internationally in beer packaging industry has developed rapidly in recent years, especially the application of PET bottle coating technology (plasma technology), which is coated with a 0.21mm carbon layer inside. Its inducement resistance is almost the same as that of glass. At the same time, it can withstand high-temperature sterilization treatment, so that its application range is expanded, and it is suitable for the packaging of hot filled tea drinks. Caimingchi pointed out that Shanghai Zijiang group and Zhuhai Zhongfu group have actively adopted new technologies, invested a lot of money in research and development, and adopted co injection technology and bottle blowing technology, which can keep beer fresh in pet for 100 days. 350 ml and 500 ml PET bottles have been tested and produced, and 1.5-liter and 2-liter beer PET bottles are being developed. At present, the two enterprises are building new factories and preparing for mass production

find the right direction for developing drinking water packaging bottles (barrels). At present, PVC and pet are the main 5-gallon drinking buckets in the market, which has brought many problems. The toxicity of PVC drinking bucket additives has been controversial. The pet drinking bucket is in line with the health requirements, but due to the chaos of the market order, inferior products are replaced with good ones, and old materials are filled with new materials, so that the bacterial content in the bucket exceeds the standard. According to the same investigation, in some places, more than 1/2 of the barreled purified water is unqualified, and the main reason is that the barrel material is non food grade. Therefore, 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

the rapid development of plastic packaging is inseparable from the market development of related industries. The growth rate of food and soft drink packaging market is more than 20%. Therefore, since this year, the transparent polypropylene market has been rapidly expanded; The implementation of green food engineering in the processing of agricultural and sideline products provides new opportunities for the plastic packaging market. Caimingchi, for example, said that the launch of Liaoning's green food industry chain involves 100 production bases in 100 counties in 9 provinces and cities, including Liaoning, Jilin, Heilongjiang, Inner Mongolia, Shandong, Hebei, Hainan, etc., including the packaging of more than 3000 varieties of grain and oil, fresh vegetables, dried and fresh fruits, fresh milk and dairy products, condiments, raw and fresh meat, poultry eggs, etc. it is a challenge to packaging from all aspects of production, processing, packaging, transportation, storage, and sales, All these have promoted the market expansion of plastic packaging materials
