Carton carton packaging industry, protect the ecological environment

[China Packaging Network News] China has about 40,000 carton factories, and about 4,500 corrugated paper production lines (including those that cannot be used). The annual output of each corrugated paper production line is about 660 square meters, and the total annual output is about 40 billion square meters, among which three Layered corrugated paper production lines account for 15%, five-layer corrugated paper production lines account for 80%, and seven-layer corrugated paper production lines account for 5%. In the United States, there are about 1,500 carton factories and 660 corrugated paper production lines. The annual output of each production line is about 6288 square meters, and the total annual output is about 41.5 billion square meters. There are about 251 carton factories in Japan and about 477 corrugated paper production lines. The total annual production is about 13.4 billion square meters. In fact, the paper box carton packaging industry is large, and it has a good effect of protecting the ecological environment.

Packaging paper is actually paper for packaging. Generally have high strength and toughness, can withstand pressure, folding, quality requirements also have different requirements according to the different uses of packaging paper. For example, the packaging paper used for industrial and agricultural raw materials (cement, fertilizers) is relatively thick and relatively strong. Generally, it is generally made of 3 to 4 layers of paper. It is also called multi-layer paper bag paper to distinguish it from packaging. Other bags of paper products. Paper used for food packaging requires hygienic, sterile, non-polluting impurities. The electronics, daily chemical, food and beverage and other industries have a great demand for packaging paper. In addition to requiring a certain physical strength, packaging paper needs to be clean and beautiful, suitable for printing multi-colored product patterns and text. To beautify products and attract customers.

Cartons vary from paper to paper, with corrugated boxes, single-layer cardboard boxes, and the like. There are three layers and five layers commonly used in cartons. Seven layers are used less. Each layer is divided into paper, corrugated paper, core paper, and surface paper. There are teaboard paper, kraft paper, corrugated paper for core paper, and various paper colors. The hand feel is different, and the paper (color, feel) produced by different manufacturers is not the same. Different corrugated corrugated shapes and bonded corrugated cardboard have different functions. Even with the same quality of facial and liner paper, due to the difference in shape, there is a difference in the performance of the corrugated cardboard. At present, there are four commonly used corrugated shapes in the world. They are type A, type C, type B, and type E. Their technical specifications and requirements are shown in Table 1. The corrugated cardboard made of A-type crucibles has good cushioning properties and is full of certain elasticity. C-type crucibles are inferior to A-type crucibles. However, the stiffness and impact resistance are better than that of the A-type crucible; the arrangement density of the B-type crucible is large, the surface of the corrugated paperboard formed is smooth, the bearing pressure is high, and it is suitable for printing; the E-type crucible is thin and dense, but also presents its rigidity. strength.

Carton carton packaging industry is large, the effect of protecting the ecological environment is good:

The carton appears in this situation. Its good environmental protection, cleanliness, and reusability have been recognized by the vast number of consumers and countries, and will not cause any harm to the environment and products during its use. Injury has effectively protected our country's ecological environment. In the process of use, it will also play a certain role in protecting some fragile products. It has very good performance. Food packaging color boxes, food cartons, tea packaging cartons, etc. are all made of cardboard boxes. The appearance and development of cartons in the market reflects China's environmental awareness, representing the distance between China and the developed countries in the world. Little bit of shortening.
