Packaging paper can be divided into ordinary wrapping paper, special wrapping paper, trademark wrapping paper, anti-oil packaging paper, moisture-proof packaging paper five. Ordinary packaging paper paper tough, for general packaging, such as kraft paper, chicken paper, etc .; special wrapping paper according to the use of the name, its nature is also different, such as fruit packaging thin and soft paper, The anti-oil wrapping paper has the function of preventing oil osmosis and exudation, such as plant parchment, tallow paper; moisture-proof wrapping paper is moisture-proof, such as asphalt, which is used for printing Paper, aluminum foil and so on. Paper made of aluminum foil backing paper and aluminum foil paper. Soft and easy to change, such as paper, and deformation does not rebound. Can be qualitative, to ensure that shading, will not fall, not light, no pollution, cheap. For high-level cigarettes, candy and other food moisture and decorative packaging. Aluminum foil is widely used, for example: aviation food packaging, general meat packaging, cigarette packaging and so on. Experts according to their application characteristics of the different, it will be divided into more than 20 varieties. Different countries due to differences in the level of economic development, aluminum consumption structure there is a big gap. In developed countries in Europe and America, for the packaging of aluminum foil products accounted for 70% of total demand. Aluminum foil in the Chinese market is mainly used as an industrial raw and auxiliary materials, packaging aluminum foil accounted for only 30% of the total domestic demand. Although the late development of aluminum foil packaging, but the market is growing rapidly, the prospects for concern. Aluminum foil in the construction of the application is quite significant, paste the surface of the insulation material to achieve its construction more convenient, clean, especially the aesthetic degree reached a new height. But different types of aluminum foil effect vary greatly, such as fire and ordinary is not a grade. China's aluminum foil production began in 1932, but until after the reform and opening up began rapid development. Since the 1990s, aluminum foil production has entered an important period, not only the introduction of a large number of advanced equipment, production management and technology development level has gradually moved towards modernization and internationalization. Since the beginning of this century, driven by strong market demand, aluminum foil production capacity increased rapidly. China has a total of more than 90 aluminum foil production enterprises, equipped with modern aluminum foil mill 66, and 39 universal cold rolling mill, aluminum foil total capacity of 500,000 tons / year. Kraft paper, used as packaging materials. High strength. Usually tan. Half drift or full bleached kraft pulp is light brown, creamy or white. Quantitative 80 ~ 120g / m2. Crack length is generally more than 6000m. Tear strength, rupture strength and high dynamic strength. Mostly for the web, there are flat paper. Using sulphate softwood pulp as raw material, the beating, in the long net paper machine made of copy. Can be used for cement bag paper, envelope paper, paper seal paper, asphalt paper, cable protective paper, insulation paper. Kraft paper is a tough water-resistant packaging paper, was brown, widely used, commonly used in kraft paper kraft paper. Making paper bags, envelopes, homework, album sets, dossiers and sandpaper. Quantitative range of 80 grams / square meter to 120 grams / square meter, there are web and flat paper, there are single-sided light, double-sided light and stripes the difference. The main quality requirements are flexible and strong, high bursting resistance, can withstand greater tension and pressure is not broken. Kraft paper has a high pull, a single light, double light, stripes, no grain and so on. Mainly used for wrapping paper, envelopes, paper bags and so on and printing presses. In the consumption of the paper, the amount of paper used in packaging is very raised. The situation in the world is generally similar, such as the United States of packaging paper consumption accounts for about 70% of the total. US annual waste paper exports accounted for 60% of the global total commercial waste paper, so the world's largest supplier of waste paper in the United States. In the recycled paper, there is a large part of the discarded paper (cardboard). In many market factors, the competition between packaging paper and plastic packaging is still quite intense. Plastic does have a lot of strength, but it can not be biodegradable, the destruction of the natural environment can not be underestimated. As a result, the packaging paper is in a favorable position. Many European and American countries even legislate to limit the use of plastic packaging, and to replace the packaging paper. To sum up, the packaging paper vision is very bright. Especially the penetration of high-tech infiltration and deepening, there is the strength to develop more and better new packaging paper. In the packaging industry, faced with all kinds of packaging paper, and strive to be well designed, clever layout, strengths and weaknesses, flexible application, in order to achieve the "need to take" the purpose of packaging.
