Description

Technical Field

[0002] Paper, also known as felt paper, is made from raw materials containing plant fibers through processes such as pulping, modulation, papermaking, and processing. It can be used for writing, printing books and newspapers, packaging, etc. It is a sheet that can be folded arbitrarily for writing. Paper is the carrier of writing and printing, and can also be used for other purposes such as packaging and hygiene, such as printing paper, carbonless paper, toilet paper, facial tissue, etc. Thanks to the invention and popularization of paper, humans no longer need to use materials such as mud, stone, wood, pottery, and metal to record words or pictures, and a large amount of ancient information has been spread and preserved. Wrapping paper is a paper material used to package various goods and products, and its design and selection depend on the characteristics of the item to be packaged, the transportation method, the storage conditions, and the market demand.

[0003] Traditional wrapping paper usually uses the method of packing the base paper in boxes, which is a classic supply and distribution method, especially suitable for large-scale paper production and distribution. Since the demand for traditional wrapping paper is usually large and stable, packing the base paper in boxes can bring cost advantages because it reduces intermediate processing and packaging links, saving related labor and equipment costs, which is particularly important for wrapping paper in large-scale production and can make the cost more competitive.

[0004] However, traditional wrapping paper is basically all packed with base paper in boxes, with insufficient moisture-proof and wear-resistant strength and poor reusability, which may cause problems for products stored in a humid environment or requiring long-term storage. At the same time, the base paper in boxes may be insufficient in terms of wear resistance, especially prone to abrasion or tearing during transportation and handling. Therefore, a moisture-proof composite wear-resistant paper is proposed to solve the above problems. Summary of the Utility Model

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Reference Figures 1-3 , the utility model provides an embodiment: a moisture-proof composite wear-resistant paper, including a composite paper body 1, both sides of the composite paper body 1 are fixedly connected to edge sealing 2, an outer coating 6 is arranged inside the composite paper body 1, the bottom of the outer coating 6 is fixedly connected to a moisture-proof layer 7, the bottom of the moisture-proof layer 7 is fixedly connected to a composite adhesive layer 8, the bottom of the composite adhesive layer 8 is fixedly connected to a base layer 4, the bottom of the base layer 4 is fixedly connected to a lining paper layer 3, transverse connecting fibers 9 and longitudinal connecting fibers 10 are arranged inside the lining paper layer 3, and a particle component is arranged on the top of the base layer 4, the particle component acts on the base layer 4 to better bond with the composite adhesive layer 8, the particle component includes surface particles 5, the bottom of the surface particles 5 is fixedly connected to the top of the base layer 4, the outer wall of the surface particles 5 is fixedly connected to the inside of the composite adhesive layer 8, the transverse connecting fibers 9 and the longitudinal connecting fibers 10 are staggered and fixed between the lining paper layer 3 and the base layer 4, the outer coating 6 is made of polymer resin, the moisture-proof layer 7 is made of polyester PET, the composite adhesive layer 8 is made of water-based glue, and the lining paper layer 3 is made of high-density fiberboard.

[0029] Specifically, the outer coating 6 is located on the surface of the composite paper body 1, and its function is to enhance the abrasion resistance and partial moisture-proof function of the paper. This layer is usually designed to protect the paper from the external environment. The moisture-proof layer 7 is located inside the outer coating 6 and is a key part of the moisture-proof composite wear-resistant paper. Its main function is to block moisture and dampness, effectively protect the packaged goods from getting damp, and maintain their quality and integrity. It is connected to the base layer 4 through the composite adhesive layer 8, so that the base layer 4 and the moisture-proof layer 7 are firmly bonded together, enhancing the stability and durability of the overall structure. In the composite paper, the base layer 4 is the main supporting layer, combined with other layers to provide strength and support for the whole. At the same time, a special design of surface particles 5 is set on the top of the base layer 4, and its function is to increase the bonding area, thereby enhancing the adhesiveness and stability of the paper. The lining paper layer 3 is the layer at the bottom of the base layer 4, and its main function is to provide additional support and flatness, enhancing the stability of the overall structure. At the same time, the transverse connecting fibers 9 and longitudinal connecting fibers 10 between the lining paper layer 3 and the base layer 4 enhance the connectivity between the two. The transverse connecting fibers 9 are located between the lining paper layer 3 and the base layer 4 and are connected along the width direction (transverse) of the paper, enhancing the bonding strength between the lining paper layer 3 and the base layer 4, preventing the paper from separating or being damaged due to tension or pressure during use. At the same time, the longitudinal connecting fibers 10 are connected along the length direction (longitudinal) of the paper, and the main purpose is to enhance the overall stability and durability of the lining paper layer 3 and the base layer 4 when the paper is stretched or extruded. The longitudinal connecting fibers 10 help the paper to maintain flatness and strength during handling and use.

[0030] Working principle: When using the moisture-proof composite wear-resistant paper, the outer coating 6 is on the surface of the composite paper body 1, playing the role of enhancing abrasion resistance and a certain moisture-proof function. Then, the internal part is protected by the moisture-proof layer 7, which is a key part of the moisture-proof composite wear-resistant paper and is used to block moisture and dampness to protect the packaged goods from getting damp. Then, it is connected through the composite adhesive layer 8 and firmly bonded together to ensure the stability and durability of the overall structure. At the same time, surface particles 5 are set on the top of the base layer 4 to increase the bonding area and enhance the adhesiveness. Finally, the lining paper layer 3 is used at the bottom to enhance the stability and flatness of the overall structure, and the connectivity between the two is enhanced by the transverse connecting fibers 9 and longitudinal connecting fibers 10.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
