Packaging paper with special materials

paper cans. At present, the annual consumption of aluminum cans in China is 6-7 billion. Raw materials need to be imported in large quantities and are expensive. Coupled with environmental pollution and other factors, the state no longer approves the construction of new aluminum cans production lines. Whether we can find new packaging containers to replace aluminum cans has become a concern of the industry. The birth of paper cans has overcome various disadvantages of aluminum cans and has broad prospects for development. It needs at least 17million yuan to build an aluminum can production line, while it only needs 2million yuan to build a paper can production line; The minimum batch of aluminum cans is 20million, and the economic batch of paper cans is more than 20000. Paper cans can be used for the packaging of paints, chemicals, food, drugs, etc., and also for the production of paper lunch boxes, paper cups, paper barrels and other products. Normal align=left> acrylic synthetic paper. Japanese experts used propylene in petroleum gas as raw material to make a synthetic paper. This paper ground is strong, not easy to crack, smooth surface, no wrinkles, not afraid of moisture, and will not change color. This kind of paper is lighter than ordinary paper and is not easy to be stained with dirt. 5. Developing bio based plastics is a good material for printing, writing and food packaging

normal align=left> foam in 2011. German PSP company has developed a new process for foam production, and its packaging materials can replace foamed plastics. This kind of foam paper uses old book scrap paper and flour as raw materials. First, the recycled old books and newspapers are cut into pieces, and then ground into fibrous pulp, which is mixed with flour in the ratio of 2:1. The mixed paper pulp is injected into the extruder and pressed into cylindrical particles. During the extrusion process, the raw material becomes foam paper under the action of steam. Using this kind of foam paper particles as raw materials, a variety of packages can be produced according to different needs. Foam paper can be shaped at one time, without chemical additives, and can be recycled and processed after use

normal align=left> hard light wrapping paper. A Finnish company has successfully developed a kind of hard and light packaging paper. This kind of packaging paper is 10% - 20% lighter than ordinary paperboard. In addition to tasteless characteristics, it also has heat resistance and printability as pure pulp board. It is especially suitable for packaging chocolate, ice cream, refrigerated food, etc., as well as various flavor packaging and manufacturing fast food boxes

normal align=left> self adhesive wrapping paper. South Korea has made a kind of self-adhesive packaging paper. The outer layer is kraft paper, and the inner layer is a special foaming material. It has elasticity and excellent corrosion resistance, which can ensure that the surface of the package is not worn. Because of its stickiness, there is no need for rope and tape when packaging. The core of test4.0 software is based on MS-Access database. The wrapping paper will automatically lose its viscosity once it is unpacked, so it also has the function of preventing people from being unpacked
