What is kraft paper? Many of the snacks we often eat are packaged in a yellow-brown paper bag. The material of this packaging bag is kraft paper. Let me introduce the details of kraft paper below. Kraft paper is just what the name suggests. It has this name because it is as strong as cowhide. Kraft paper is made from the fibers of the kraft conifer, chemically pulped, then put into a beating machine to be beaten, and sizing dyes are added to the paper machine to make it. The color of kraft paper is yellowish brown, and the paper is tough. It can be used as cement bag paper, envelope paper, glue sealing paper, asphalt paper, cable protection paper, insulation paper, etc. The principle of kraft paper was introduced above. It is a yellowish-brown paper, which is very strong. Kraft paper can be classified as follows according to different properties and uses. According to the different materials, it is divided into: kraft base paper, kraft core paper, wood pulp kraft paper, recycled kraft paper, etc. According to the different colors, it is divided into: single-gloss kraft paper, two-color kraft paper, primary color kraft paper, white kraft paper, etc. According to different uses, it can be divided into: pattern-making kraft paper, composite kraft paper, insulating kraft paper, waterproof kraft paper, packaging kraft paper, etc. Then there is a question, the manufacturing process of kraft paper is no different from ordinary paper, but kraft paper is stronger than ordinary paper? This is mainly because the wood fibers used in making kraft paper are relatively long. During the process of cooking wood, they are treated with caustic soda and sulfide soda chemicals, so that their chemical effects are more moderate, and the original strength of wood fibers is affected. The damage of the kraft paper is relatively small, so the paper made of this kind of pulp, the fiber and the fiber are closely dependent, so the kraft paper is very strong. It is because of the fact that kraft paper is very strong, has high breaking resistance, can withstand greater tension and does not break under pressure. So kraft paper is often used to make: gift paper bags, packaging boxes, and envelopes. Workbooks, files, etc. It is used in various fields, and it can be seen in many industries such as chemical, machinery, food and other industries. Among them, cowhide bags are particularly widely used in the food packaging industry. Food packaging bags or food packaging boxes made of kraft paper have good tensile strength, are not easy to deform, and can protect the food from damage and maintain the taste and appearance of the food. Kraft paper can also be combined with a variety of processes, so there will be many Merchants will use bronzing or embossing processes on kraft paper packaging belts. Make the packaging firmer while adding a sense of exquisiteness and three-dimensionality, which is more attractive to consumers. The above is the entire content of the kraft paper introduction.
