The application of new material in the packaging design

【 Abstract 】 New materials of excellent properties make it popular in the field of packaging, new nanometer material and new polymer materials, new type metal materials has been widely used in packaging, including applied research in the field of packaging has been deeply, in this paper, the new packaging materials as the research object, discusses the characteristics and application of new packaging material. 【 Keywords 】 Packaging design new material properties and application of the introduction of new materials science is the end of the 20th century the rise of one of the most important areas of science and technology, because the new materials in many fields such as People's Daily life has great influence, the world attaches great importance to research and development funding. The United States since 1991 has classified nanotechnology & other; The government key technology & throughout; ； The nano science research in China on & other; 863 plan & throughout; Key research projects. Along with the new material science theory is increasingly mature, expanding the application areas of new materials. Commonly used materials in the traditional packaging design have paper, glass, plastic, ceramic, metal, wood, chemical fiber, etc. With the constant progress of science and technology, new material appear constantly, people's material and spiritual demand unceasing increase, more and more is also high to the requirement of packaging design. Application of material science, reasonable, make full use of materials, material properties, on the basis of perfect packaging purposes, is the target of each packaging design. 1 packaging materials in packaging design, the application of composite nano packaging materials of excellent properties make it popular in the field of packaging, packaging for antimicrobial packaging materials, nano material, nano high barrier property has set up a file in the food packing such as packing material to have certain application. The application research in the field of food preservation have deeper. Made of nanometer composite technology get phthalein money - new packaging materials 6 plastic ( NPA6） Compared with the traditional nylon plastic, have more superiority. The oxygen and carbon dioxide through rate fell by half, water through rate also fell by about 30%. Use it for packing food, such as sausage, ham, pickles, etc. , the metamorphic grade of food smaller, longer shelf life. Add 0. 1% ~ 0. 5% of packaging material made of nanometer TiO2 can prevent ultraviolet light meat caused by automatic oxidation, protect vitamin and aromatic compounds from destruction, to keep the food fresh. Nanometer silver powder used in food packaging, there are both antibacterial and preservation effect of bacteria and moulds, antibacterial effect is good, time is long, added to the food packaging materials can keep the long-term antibacterial effect, and not caused by evaporation, dissolution, or light color change or food contamination; At the same time, the nanometer silver powder with catalysis of ethylene oxide in fresh-keeping packaging material to join the nanometer silver powder, fruit and vegetable food can be release ethylene accelerated oxidation, reduce ethylene content, to achieve the effect of fresh-keeping. 2 the application of new polymer material in the packaging design KratonA polymer is a kind of unique and excellent performance of synthetic rubber, given its unique molecular structure can be controlled accurately, suitable for special purposes. After composite polymer produced materials, can improve the packaging film in applications such as viscosity, elasticity, beautiful degree, etc. Advantage is able to improve the viscosity of substrates, precision casting, volume stability and hardness. New anti-fog film can eliminate the chilly additive matrix formed by the mist, improve the aesthetic and the appearance of the product packaging. Compared to the previous product, but also can extend the validity of the packaging products. Made from dry sealing film of high barrier property of the composite bags, higher performance by customers favor. The dry sealing film to eliminate possible in all aluminum foil heat seal moisture entrance, and inhibition of moisture in the process of packaging and processing by the holes or aluminum foil into the bag. The new material to reduce the packaging cost, and is very suitable for the application of food packaging. PVDC is a pale yellow, powder material of high barrier property. In addition to have plastic general performance, but also has the self-extinguishing, oil resistance, and excellent properties, such as moistureproof, mouldproof, also has excellent printing and heat sealing performance. PVDC in plastic packaging in the world today is blocking performance better a packaging material. It is different from poly (vinyl alcohol) with the increase of moisture absorption and make the carbamate resistance fell sharply, and different from nylon membrane wet due to water resistance performance, but a wet resistance, resistance to high barrier performance materials that are better. It not only has excellent high separation performance, but also has excellent printing performance, composite performance and transparent properties. In practice, PVDC coated film for printing ink and equipment without special requirements, so there is no need to change process of each process and can greatly improve the production efficiency, reduce the cost. Use of PVDC composite packaging than the ordinary PE film, paper, aluminum foil, wrapping shoes to cut a lot, so as to achieve the packing and reduce waste source reduction purposes.
