Description
Technical Field

Background
In general, the packaging industry often selects paper as the primary packaging material, and in order to ensure the tightness of the package, the related art often employs extruded polyethylene to assist the paper in providing a closed package. This approach can increase the mechanical strength of the packaging material to some extent, but it does not ensure the stability of the package by coating the polyethylene with a thicker paper film. Furthermore, such higher grammage paper and extruded plastic layers also increase the final packaging costs. More importantly, polyethylene materials cannot be rapidly degraded in natural environments, which brings certain environmental pollution problems to the packaging industry.
In view of the above, it is important to design and manufacture a reinforced degradable special paper capable of overcoming the above problems.

Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The present utility model will be further described in detail below with reference to the drawings and detailed description for the purpose of enabling those skilled in the art to better understand the aspects of the present utility model.
Referring to fig. 1 to 2, an enhanced degradable specialty paper comprises a paper base layer 1; one side of the paper base layer 1 is connected with a plant-based resin grid reinforcing layer 2 in a penetrating way, and the plant-based resin grid reinforcing layer 2 is used for reinforcing the strength of a product and improving the durability of the product; the water-based heat-seal type modified resin layer 3 is uniformly and finely applied to the surface of the plant-based resin grid reinforcing layer 2 in a rotogravure coating mode at one side of the plant-based resin grid reinforcing layer 2; the water-based heat-sealing type modified resin layer 3 is used for ensuring the sealing performance of the product and providing a safe and sanitary use environment for users.
The preparation method comprises the following steps:
first, biodegradable plant-based resins are used to create extremely strong chemical pulp fiber bonds. The special plant-based resin penetrates the paper-based fiber layer at its surface layer, thereby producing excellent adhesion in the product. Meanwhile, the product is provided with a better moisture-proof barrier, and the quality and durability of the product are fully ensured. The main components for this particular biodegradable plant-based resin include: the novel oyster water-based organic silicon comprises 25 to 35 percent of acrylic styrene copolymer, 50 to 60 percent of natural plant wax and 10 to 20 percent of softened water, wherein the total weight of the acrylic styrene copolymer is 25 to 35 percent of the total weight of the acrylic styrene copolymer, and the water-based organic silicon is 0.8 to 1.2 percent of the total weight of the base oyster. The substances are matched according to different proportions, and the excellent effect is exerted in practical application.
Secondly, after the laying of the basic reinforcing layer structure is completed, the water-based heat-sealing modified resin is applied to the structural layer (the plant-based resin grid reinforcing layer 2) in an effective manner so as to improve the sealing property and the protection performance of the whole structure. To accomplish this, a rotogravure coating technique may be used in production to apply the modified resin to the surface of the reinforcing layer in a uniform and fine manner by specialized coating equipment to ensure the quality and effect of the coating, and in addition, for special pattern designs, an engraving cylinder having a honeycomb design may be used to apply the modified resin precisely to the paper substrate to achieve the desired sealing effect. A honeycomb design refers to any closed structure that is closed and has a significantly repeating pattern or design, such as square, diamond, triangular, honeycomb, etc., all for the purpose of achieving a stable and reasonable structural layout. In addition, the process using the gravure coating technique should include an electrostatic field process ESA by which the modified resin can be efficiently and precisely infiltrated into the inside of the plant-based resin and the inside of the paper-based resin.
Finally, in order to ensure the closing function of the package, the aqueous heat-sealing type modified resin should have a melting temperature equal to or higher than 70 ℃ and be capable of achieving good compatibility with the plant-based reinforcing resin and the paper-based in its molten state. The use of such heat-sealing resins replaces and eliminates the use of liquid or viscous adhesives, thereby reducing contamination during production and improving the environmental performance of the package. The water-based heat-sealing type modified resin can be acrylic or polyurethane type modified resin, and the two types of resin can realize good heat-sealing effect and have better environmental protection performance.
The two operations can finish the manufacture of the enhanced degradable special paper, and the tensile strength of the manufactured product is obviously improved by 18.9%, the water absorption is reduced by 15%, and the moisture resistance is increased by 16%. Therefore, the enhanced degradable special paper not only has excellent performance, but also realizes remarkable innovation. It is further appreciated that it allows for a reduction of the paper base reuse of about 15% while still maintaining the original level of protection. Such a result clearly offers more possibilities for packaging cost savings. The higher tear resistance not only improves the physical strength of the package, but also reduces the hygroscopicity, thereby maintaining the mechanical strength characteristics of the package more stable and more durable. For example, if the mechanical strength is increased by 12%, we can scale down the thickness of the paper, further reducing the cost per package while achieving the same packing capacity. More importantly, if the moisture in the paper can be successfully reduced by 15%, the paper strength in the package increases significantly, which will make the package less prone to breakage when wet.
The vegetable resin used in the utility model provides excellent strength with less material, which provides significant advantages for optimizing the characteristics of the package while reducing the weight of the package. This approach not only reduces wastage of packaging material, but also reduces packaging costs, thereby providing a more economical alternative to consumers. More importantly, the paper has higher physical strength and simultaneously can keep excellent degradation performance, so that the paper can be safely and rapidly decomposed by microorganisms in nature after the history service of the paper is completed, and no burden is caused to the environment.
The above description is only of the preferred embodiments of the present utility model, and is not intended to limit the present utility model in any way, although the present utility model has been described above with reference to the preferred embodiments, and is not intended to limit the present utility model. Any person skilled in the art should make equivalent embodiments belonging to equivalent changes and modifications by using the technical content disclosed in the above description without departing from the technical content of the present utility model, but any brief introduction modification, equivalent changes and modifications made to the above embodiments according to the technical substance of the present utility model still fall within the scope of the technical solution of the present utility model.
