The current world trends and characteristics of plastic packaging

(57.5%) after the No. 2 ranking, and the remaining 12% of metal, glass 9.2%, wood products 5.2%, other 0.7%. A 45 - According to the United States, Japan and the development and prediction of major powers, it is clear that plastic packaging materials in the 21st century will continue to grow steadily in the field of packaging materials is still full of vitality, in the protection of goods, improve the value of the goods to continue play an active role. 2. Barrier, the versatility of plastic packaging materials, the development of many countries hot high barrier packaging materials, plastic packaging materials, the versatility of hot spots in many countries the development of packaging materials, and some products have been put into industrial production. Such materials include high resistance and permeability, multi-function preservation, choice permeability, heat resistance,[link widoczny dla zalogowanych], sterility (bacterial) resistance, and rust, odor, shape memory, longer letters, and so easy to Kaifeng, plastic packaging materials, Among them, high resistance and permeability function preservation, the development of aseptic packaging materials more rapidly, will be the focus of early 21st century development. The early 21st century, with the growing world economy, the continuous development of high technology and product advances, people's lives has become more convenient and leisure. Both commodity packaging, food packaging, industrial packaging have a higher demand, the other day with the strong environmental voice. To meet the packaging functions under the premise of minimizing the amount of waste generated, and thus present packaging films, containers, sheets to lightweight, thin-walled development trend, the key technology is the active use of super toughness, can be processed thinner than easy processing of new materials, such as the bimodal polymer HDPE, metallocene catalyst polyethylene, polypropylene and polystyrene plastic alloy, a plastic packaging offers more choice of materials, especially polyethylene, polypropylene,[link widoczny dla zalogowanych], development further improve the structure of many of the properties of flexible packaging, such as toughness, transparency, resistance and permeability, heat resistance and puncture resistance, etc., and can reduce the sealing temperature, improve processing and increase packaging line speed: polyethylene food One of the characteristics of packaging films to control the oxygen, carbon dioxide and water vapor permeability, can be used to control MAP, greatly extending the shelf life of food, mainly for the supermarket salad, carrot b films, cauliflower and meat packaging and preservation of agricultural products such as semi-finished bags, shrink resistance and permeability bags and so on. USA 2000, such semi-finished shelf capacity will be 3% of the mid-90s to 25%, agricultural products sold in the form of fresh picked to reach 25%, modified atmosphere packaging films on the MPE control greatly increased the demand will follow. 3. Energy saving, environmental protection, recycling and easy starting point for technology development is the environmental century 21st century, environmental issues increasingly important resource, more nervous energy, plastic packaging materials will usher in new opportunities, will also be subjected to severe challenges, to meet the new age, plastic packaging materials in addition to the market to meet the packaging requirements of the quality and effectiveness of increasing demands, but also further requested the save energy, save resources, easy to be recycled after use, or susceptible to environmental degradation of the starting point for technology development. To this end, a positive high barrier plastic packaging materials, versatility, environmental adaptation, using new materials, new processes, new equipment and expand the application areas such as direction. 4. Development of anti-static, conductive soft plastic packaging materials,[link widoczny dla zalogowanych], with broad prospects for development is an information age of today. Various frequencies, the wavelength of the electromagnetic waves fill the earth and space: these electromagnetic waves of electronic components, circuit boards, computer communication equipment, different degrees of interference, resulting in distortion of data, communication disorders. The electromagnetic induction and the static friction of electronic components, instruments, meters, high voltage generated by the accumulation of static electricity would be devastating. Therefore, the development of anti-static,[link widoczny dla zalogowanych], conductive soft plastic packaging materials, and has broad prospects for development. 5. Plastic blends, plastic alloys, inorganic materials, reinforced composites filled with (ABC) tomorrow, plastic star. Star of Tomorrow has been hailed as the plastic blend of plastic, plastic alloys, inorganic materials, reinforced composites filled with (ABC) based in the 20th century, through the joint efforts of both basic research, production and processing technology will further enhance the and improvement of product performance improvements and a series of ratio, functional aspects will also be greater progress in improving the quality of plastic packaging, value added and environmental adaptability and the development of new products will have a greater impact. With the improvement of the quality of plastic packaging products, increased functionality and the continuous development of new varieties,[link widoczny dla zalogowanych], but also to further expand its use, especially in high barrier food packaging plastic packaging materials mainly from the broadened progressively more non-food packaging, including industrial packaging , pharmaceutical packaging, agricultural packaging, building materials, packaging, packaging supplies and so navigation will be further developed. ·----- 46 ·-----
