Description

Technical Field

[0001] The utility model relates to the technical field of kraft paper, in particular to a wrinkle-resistant kraft paper. Background Art

[0002] Kraft paper is one of the main types of paper used for cartons. Domestic boxboard is divided into three grades: superior, first-class and qualified. The texture of kraft paper must be tough, with high burst resistance, ring crush strength and tear resistance. In addition, it must have high water resistance. The testing items include: quantitative, thickness, tightness, burst resistance, burst resistance index, ring crush strength, transverse ring crush index, tear length, tear resistance, sizing degree, moisture, horizontal quantitative difference, transverse folding resistance, etc. The purpose of boxboard is mainly to bond it with corrugated paper core to make corrugated paper boxes, which are used to package household appliances, daily necessities, needle-cotton fabrics, cultural supplies, and outer packaging of Chinese and Western patent medicines. The raw materials used for boxboard are sulfate wood pulp, waste hemp pulp, cotton stalk pulp, waste paper pulp, and rice and wheat straw pulp. The requirements for boxboard are that it should have certain compressive strength, toughness, burst resistance, tear resistance, and smooth paper surface, and no pulp lumps or knots are allowed. The good surface flatness of kraft paper also provides a guarantee for printing high-quality images. In addition, kraft paper is also one of the most commonly used materials for making ornaments, handicrafts, models, etc. The good hardness and load-bearing capacity of kraft paper make it very suitable for making various high-detail and high-precision handicrafts. It can also be used for handmade greeting cards, decorations, puzzles, etc., providing a better material choice for handmade products. Kraft paper has excellent physical properties and durability, but there are also some limitations. For example, due to the complex production process of kraft paper, its cost is relatively high. Kraft paper is usually heavier, which is not suitable for applications that require lightweight materials. However, these shortcomings cannot conceal the wide application of kraft paper and its status as an important material. In short, kraft paper is an excellent cardboard material.
