The development of packaging materials and ecological research
Corn plastic. This cup just 40 days in the open environment, disappeared without a trace. Well-known Japanese electronics maker Sony has been two years of plastic made from corn paper packaging MD disc. New packaging and packaging in the past, like beauty, but would not have a Chemical giant DuPont products are added to the development of corn plastics ranks, the company's research also received the U.S. Department of Energy $ 19,000,000 for financial support. Soy protein edible packaging film: wide range of uses for a variety of instant foods. After the main meal with soybean extract the remaining material for the production, a vast source of raw materials. Especially in the north region is rich in soy abundant raw materials. Preparation of the soybean meal is used after the residue, so the price is extremely cheap. The packaging film can not only oxygen into the resistance, but also retain moisture, but also to ensure the flavor. This edible packaging film applications in the food production industry in a very wide, most candy, cakes can be used, as the packaging features a fresh and abundant raw materials, so there are excellent prospects for industrial packaging films of chitosan edible : This edible packaging, food packaging waste to solve the contradiction between environmental protection, used in candy, preserved fruit, fresh cakes, moon cake fresh and so on. The packaging film used as the main shellfish extract raw materials,[link widoczny dla zalogowanych], chitosan, chitosan and lauric acid together to generate even edible film, and packaging with the packaging film peeled fruit and fruit slices,[link widoczny dla zalogowanych], there is also a Preservation good. The packaging materials used in the case of chitosan is shellfish processed by the crushed product. As from natural, environmental pollution, food supplement on the human body after the effect of trace elements, can be described as a new type of environmentally friendly food packaging. The downside is the limited sources of raw materials. Composite edible packaging film: the different proportions of protein, fatty acids and starch synthesis together to produce different physical properties of edible film. The product can be adjusted according to the food packaging film soft, the hardness, the formation of different types of inner packaging, in the food industry should have a huge market. 4. New Paper Packaging (1) paper packaging Films. Development of high performance packaging films instead of paper commonly used in food packaging plastic films very promising. The moisture-proof cellophane such treatment can be used for food and cosmetics packaging. Germany Fu Langhuo Seoul where the successful development of Applied Polymer Research Institute has recently only a few microns thick high-strength paper membrane, with tear, moisture, easy to seal, can be blown into type, speed and other characteristics of biological decomposition. (2) honeycomb sandwich board. Is an intermediate natural honeycomb paper core, upper and lower sides of the cardboard glued, with a light, strong,[link widoczny dla zalogowanych], just, stable four advantages, there are very good cushioning properties and mechanical strength,[link widoczny dla zalogowanych], suitable for packing fragile items such as glass, precious equipment and precision instruments. Eco-packaging materials by the world's attention, the research from the development, design, production, use,[link widoczny dla zalogowanych], disposal and so the whole process of consideration. Nano-plastics have excellent physical and mechanical properties, high strength, heat resistance, good gloss and transparency, high barrier, excellent processing performance, which is eco-friendly materials, can be used for food, all kinds of chemical materials, toxic substances packaging. Institute of Chemistry / Molecular Science Center, State Key Laboratory of Engineering Plastics successfully developed a polyamide (PA6 and PA66), polyester (PET and PBT), polyethylene, polystyrene, epoxy resin and a series of nano-plastics, and to achieve some of the industrial production of nano-plastics. Nanocomposites in food packaging market has great potential. Nano plastic such as polyamide 6 (FIE-PA6) film made with slices, blow molding and extrusion can be prepared by thermal casing film, biaxially oriented film composite membrane, with ordinary PA6 $ H ~ L, with a better barrier properties, mechanical properties and transparency. Using nanotechnology, a highly efficient catalytic CO, the synthesis of biodegradable plastics, from Chinese Academy of Sciences Guangzhou Institute of Chemistry developed. With CO, and propylene oxide polymerization of biodegradable plastics that can replace the widely used currently on the market fast food packaging containers, which addresses the CO, the resulting environmental problems, and avoid the use of plastic packaging produced white pollution. Gene technology is also one of the research direction, the use of advanced targeting the design of artificial gene splicing technology that allows plants to grow in accordance with the design requirements of people of various shapes and colors of the container (even those pre-designed container can also grow by various patterns and designs), such as a variety of milk, juice, vinegar, packaging, packaging of all kinds of disposable tableware may be cut from a genetically re-grow directly on the corn plant, the future of the bottle may be from one created by genetic modification technology directly harvested pepper plants.
