Abstract
Description
Technical Field
[0001] This utility model belongs to the field of moisture-proof paper tube technology, and particularly relates to a high-heat-wire moisture-proof paper tube. Background Technology
[0002] Paper tubes have a wide range of uses. In the packaging industry, they can be used to beautifully package cosmetics, pharmaceuticals, and food. In the textile industry, they are used to neatly wind yarns and threads. In papermaking, they are used as rolls to wind paper. They are also commonly found in the electronics, building materials, and home furnishing industries. Paper tubes are produced through processes such as rolling, gluing, and cutting. They have outstanding advantages: the natural paper raw material is environmentally friendly and recyclable; the production process is simple and inexpensive; and they are lightweight and easy to transport and store.
[0003] Commercially available paper tubes generally have low strength, making them prone to deformation under stress, which can damage the items inside. Furthermore, the inner wall of common paper tubes is often weak, making it susceptible to scratches from repeated handling, thus affecting the tube's lifespan. In addition, paper tubes typically have poor moisture resistance, meaning they easily become damp and soften when exposed to humid environments for extended periods, potentially damaging the contents. Therefore, we propose a high-heat-resistant, moisture-proof paper tube. Utility Model Content
[0004] The purpose of this invention is to provide a high-heat-proof moisture-proof paper tube to solve the problems mentioned in the background art.
[0005] In view of this, the present invention provides a high-heat-wire moisture-proof paper tube, comprising:
[0006] A paper tube is provided with a wood pulp layer on its peripheral wall, a fiber layer on its peripheral wall, a moisture-proof layer one on its peripheral wall, a waterproof layer on its peripheral wall, a bamboo pulp layer on its inner wall, a moisture-proof layer two on its inner wall, and a wear-resistant layer on its inner wall.
[0007] In this technical solution, the paper tube made by combining the above-mentioned materials has the advantages of high strength, good moisture resistance, strong tear resistance, good wear resistance, good gloss and good puncture resistance, which can effectively protect the contents.
[0008] In the above technical solution, the supporting paper tube is made of kraft paper, and the wood pulp layer is made of softwood pulp.
[0009] In this technical solution, the kraft paper used for supporting the paper tube has high strength and toughness, good burst resistance and tear resistance, and can withstand certain pressure and tension. It is not easy to break during winding or use. At the same time, kraft paper itself has certain moisture-proof properties, and its fiber structure is relatively dense, which can block the intrusion of some moisture.
[0010] The softwood pulp used in the wood pulp layer mainly comes from coniferous trees such as pine and spruce. The fibers are long and thin, with an average length of 2.5-3.5 mm. The cell walls are thick, and the cellulose content is high, usually above 90%, while the hemicellulose content is relatively low. Due to the long fibers and high cellulose content, paper made from softwood pulp has high tensile strength, tear strength, and bursting strength. It can withstand greater tension and pressure and is not easily broken.
[0011] In the above technical solution, the fiber layer is further made of polyester fiber.
[0012] In this technical solution, the polyester fiber used in the fiber layer is made by chemical polycondensation of organic dicarboxylic acid and diol. The fiber has high strength, good elasticity, and good chemical corrosion resistance and abrasion resistance. The polyester fiber has a small diameter and can be processed into different shapes and specifications. When added to paper, it can significantly improve the tensile strength, tear strength and abrasion resistance of the paper, making the paper less prone to damage during long-term use.
[0013] In the above technical solution, the moisture-proof layer is further made of polyvinylidene chloride.
[0014] In this technical solution, the polyvinylidene chloride used in the moisture barrier layer has excellent barrier properties, providing good protection against moisture, oxygen, and odors. The PVDC coating or film can be laminated with paper to form a packaging material with high moisture-proof performance.
[0015] In the above technical solution, the waterproof layer is further made of polyethylene.
[0016] In this technical solution, the waterproof layer uses polyethylene. The polyethylene film can effectively block moisture and play a good moisture-proof role. Moreover, the surface of the coated paper is smooth, which is conducive to the tight bonding between the paper layers during the paper tube winding process, making the paper tube structure more stable.
[0017] In the above technical solution, the bamboo pulp layer is made of bamboo pulp material.
[0018] In this technical solution, the bamboo pulp layer uses bamboo pulp material, whose fibers are fine and tough, typically 1.5-2.5 mm in length. The bamboo pulp fibers have a high cellulose content and a relatively low lignin content, resulting in paper with high strength and stiffness, good support, and good smoothness and gloss.
[0019] In the above technical solution, the second moisture-proof layer is made of calcium carbonate, and the wear-resistant layer is made of polypropylene fiber.
[0020] In this technical solution, the second moisture-proof layer uses calcium carbonate material. Calcium carbonate is often used as a filler. On the one hand, it can improve the whiteness and opacity of paper. On the other hand, calcium carbonate particles can fill the pores of paper, making the paper structure more compact, thereby improving the paper's moisture-proof performance.
[0021] The wear-resistant layer uses polypropylene fiber, a thermoplastic synthetic fiber, which is lightweight, high-strength, corrosion-resistant, and wear-resistant. The surface of polypropylene fiber is smooth, with a low coefficient of friction, making it less prone to wear. Adding polypropylene fiber to papermaking can improve the paper's wear resistance and puncture resistance, while also reducing the paper's water absorption and improving its moisture resistance.
[0022] The beneficial effects of this utility model are:
[0023] This high-heat-resistant moisture-proof paper tube, made by combining a supporting paper tube, a wood pulp layer, a fiber layer, a moisture-proof layer one, a waterproof layer, a bamboo pulp layer, a moisture-proof layer two, and a wear-resistant layer, has the advantages of high strength, good moisture resistance, strong tear resistance, good wear resistance, good gloss, and good puncture resistance, and can effectively protect the contents.
