The development trend of the packing materialOur packing industry, as a new industry, the development process of the party and state leaders are concerned, the recognition and support. After 20 years of development, our packaging industry experience from scratch, from the development course, the annual growth rate than 18% to develop rapidly, from the early 1980s 40 major industries of national economy, the last one to the 14th, now in total industrial output packaging society by the proportion of the early 1980s 0 40 to 4. 05%.Our packing industry include paper, plastic, glass, metal, machinery, printing industry is six. Because of the market economy and to promote the progress of technology driven, packaging industry of industrial structure and product structure has changed greatly, representing the new direction of development of modern packaging paper, plastic packaging materials and products in a fast growth, packaging products output proportion had different degrees of improvement. At present, China has become the world after the United States and Japans third largest packaging nation.A type of packaging materials and application1, packaged materialsWrapped around the world packaging materials of material, the highest proportion, is the most important industrial packaging materials, paper packaging of pollution, biodegradable, to realize the sustainable development of green packing requirements to have the important meaning. In the paper, however, the irrational use packing also can cause serious environmental problems caused by, resource crisis. In recent years, Chinese residents of paper consumption statistics showing rising, packaged products from 2006 to 2010 will reach 2.7m tonnes from 2011, by 2015, is expected to reach 3600 tons. Packaged materials can get the favour of people, because it has a series of many other materials can not replace the outstanding advantages. Firstly, the paper material itself with excellent performance. The paper source extensively, cheap, low cost and good performance of processing, printing and excellent performance, has certain mechanical properties. Secondly, opaque varieties, good health, good flexibility and tenacity, easy to form of mass production. In addition, with convenient transportation, lightweight, small shrinkage, high stability, non-friable and easy cutting, etc. Again, use thin and has good paper cut composite packaging items can prolong life. The goods, It is the traditional healthy food and pharmaceutical packaging materials, to advocate natural, wrapped in modern popular.In recent years, in order to eliminate the white pollution, in the world with a hot paper and plastics, effectively promote the wrapped in plastic packaging, promote the replace of composite paper, aluminum foil, second coating paperboard, high gloss paperboard etc. Due to the carton packaging transportation to gradually develop commodity packaging, wrapped in higher accuracy. Extensive use of packaged and die-cutting, stationery, drugs and other new technologies, not only can protect product packing, prolong service life, also have packing products, the display of the product can improve the aesthetic feeling, give a person with visual enjoyment, causing consumers buy, promote sales.In the paper, plastic, metal, glass, wrapped in four packaging materials, the cheapest materials and can be recycled and used again. Currently the new trends in the development of packaged mainly include: packing paper, paper quality lightweight, Developing composite bag, Special functional food development of packaging, Development of plant fiber packing materials, Using natural green packaging materials, Develop pulp moulding products, etc. Paper pulp is a three-dimensional papermaking technology, is in MoSuJi by special die out certain shapes of paper. With four: one is the source of raw materials, including waste paper, cardboard boxes, corrugated board paper, white paper, etc. 2 are process by pulp, adsorption, drying, environmentally sound shape. Three can be reused. Four is small volume, overlapping foamed plastics, the transportation is convenient. Paper pulp molding tableware, can be made in the matter, still can make the cushion packaging industry products, developing rapidly.2, plastic packaging materialsPlastic because it is qualitative light, intensity tall, waterproof, abrasion resistance, corrosion resistance, blocking and chemistry stability is good and inexpensive advantages and are widely used in packing, machinery manufacturing, shipbuilding, automobile, electronics, chemical industry, agriculture, etc, are the metal, inorganic materials after the third generation materials. China is the world packaging production and consumption, plastic packaging in packaging industry output proportion is expected to exceed 30%, 2011 until 2015, plastic packaging industry output is expected to breakthrough 600 billion yuan, yield reached 9.46 million tons.Due to the lo
