Plastic packaging industry development trend analysis

China is the world's packaging manufacturing and consumption power, effervescent tablets bottles in the packaging industry output value proportion of more than 30%, become a vital force in the packaging industry, cosmetics, daily necessities and industrial and agricultural production areas play an irreplaceable role. In recent years, plastic packaging industry's sustained and rapid development in our country, the industry scale continues to expand, new products, new technology, rapid progress in the development and application of new materials, new equipment, has formed a certain scale, occupies an important position in the packaging market, the positive effects on construction of the national economy. The late plastic packaging industry will develop from the following several aspects. A, new polyester packaging clueless: compelling in the world of polyethylene naphthalate formic acid glycol ester ( 笔) Is a new kind of polyester include material. Due to the molecular structure of the PEN and PET similar to instead of benzene, naphthalene ring PEN is better than PET has excellent barrier property, especially the carbamate resistance, prevent ultraviolet linear, heat resistance, Ordinary amorphous PEN thermal deformation temperature of 10007 ℃, and PET only about 70 ℃) 。 In the near future, PEN will pour into packaging, again after the PET packaging revolution. Second, the new type of degradable plastics, with the international environmental standards ISO14000 implementation of new biodegradable plastic much attention. Germany BASF introduced a brand for ECOHEXD aliphatic diol and the degradation of aromatic dicarboxylic acid polymerization of polyester resin, can be used for film production. According to introducing, the degradable plastics market demand for 20000 tons, the main application field for compost bottles, cosmetic packaging tubes, plastic, composite paper, fast food packaging container and cup, etc. Three, vigorously develop metallocene plastic: metallocene is formed by transition metal connected with cyclopentadiene organometallic coordination compounds. Metallocene polyolefin is that metallocene coordination compounds ( netallocene) As a catalyst for olefin polymerization of polymers. Metallocene polymers have many advantages, such as processing performance, high strength, high rigidity and excellent transparency, good performance, thus received the great attention, and therefore the launched many new products. Metallocene plastic will directly impact PP, MDPE often present PE, LLDPE, elastomer plastic city in the world demand for 40 million tons, the meter by 2005 will increase to 50 million tons, most parts of the increase of metallocene polyethylene. Metallocene plastic has many advantages, such as good gloss, high melt strength and membrane stability, is suitable for cosmetic packing, five layer pipe, shrink film and health supplies, etc. Four, foamed plastics towards zero pollution: A - Italy The extrusion foaming of PP MUT company village is a new development of foam plastic products. The MOH - its application TELL the company's high viscosity resin, high melt strength polypropylene ( HMSPP） , PP homopolymer with low ODP cosmetics foaming agent, produce have tiny pores and uniform distribution of foamed polypropylene sheet ( EPP) 。 Foamed PP used HMSPP accounted for only 12. 5%, has great economic significance and environmental significance: it compared with PP sheet has the same performance, the product density is low, you can save 20% of the raw materials, thus saving 20% because of the destruction of ecological environment required to pay fees. Packing foam production along the exhibition the CFC - as - the road development of HFC - HC, is being low to zero ODP and GWP, low pollution green technological advance. Five, the combination of opening up new ground: in 1997, the world's production of PP is as high as 23 million tons, the competition is very fierce. Two-way stretch PP film is growing rapidly in recent years, the 1997 world BOPP production capacity has reached 2. 82 million tons, 6% higher than in 1997 and 1998. EXXON, PMT, Bruckner, is still a two-way stretch film production companies of large manufacturers. The international market competition is intense, make firms more collectivization, the production rationalization, competition heats up.
