Description

Technical Field

[0001] The utility model relates to the aviation field, in particular to a special composite paper for aviation. Background Art

[0002] The paper used in the aviation field is generally ordinary A4 paper. The material of A4 paper is usually offset paper, also known as dowry paper, which is made of bleached coniferous wood chemical pulp and an appropriate amount of bamboo pulp. In addition, there is a light offset paper called Monken paper, which is also common in domestic book printing. The raw materials of A4 paper can include plant fibers (such as wood, bamboo, grass, etc.), mineral fibers (such as asbestos, glass fibers, etc.), and other fibers (such as nylon, metal wire, etc.). Different combinations and proportions of these materials can affect the characteristics and uses of A4 paper.

[0003] At present, there are deficiencies in the structure of paper used in the aviation field, and the structural design is unreasonable. Many passengers will fold the A4 paper next to their seats into garbage bags for use. When using garbage bags folded from A4 paper to place garbage, they will encounter difficulties in positioning the garbage bags. The garbage bags will easily rot when they come into contact with water and are very easy to be damaged, making them inconvenient to use. Bacteria are also easy to breed in the garbage bags, which will affect the environment in the cabin. Utility Model Content
