Description

Technical Field

[0001] The present invention relates to the technical field of printing and packaging, and in particular to an electronic equipment packaging protection structural component and a manufacturing method thereof. Background Art

[0002] During the packaging and transportation of electronic devices after they leave the factory, in order to prevent them from being damaged by bumps, friction, or other damage, they are usually wrapped and protected with packaging protective structures, such as the mobile phone packaging protective film disclosed in the patent document with authorization announcement number CN219949154 U.

[0003] Existing electronic device packaging and protective components are primarily made of plastic film or wax paper. Plastic film has poor biodegradability and cannot meet environmental protection requirements in some regions. While wax paper is biodegradable, it is also hard and brittle, and breaking wax paper can cause scratches on electronic device surfaces.

[0004] Cotton paper is a type of paper made primarily from cotton fiber through pulping and papermaking processes. Its core characteristics are softness, lightness, breathability, good moisture absorption, high fiber purity, non-irritation, good biodegradability, and environmental friendliness. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to propose an electronic equipment packaging protection structure and a manufacturing method thereof based on the above-mentioned deficiencies of the existing technology, which solves the problem that the existing electronic equipment packaging protection structure has poor degradability and causes scratches on the surface of the electronic equipment.

[0006] The technical solution of the present invention is achieved as follows: A method for manufacturing an electronic equipment packaging protection structure comprises the following steps: (1) Providing tissue paper, and applying heat sealing oil on the reverse side of the tissue paper; (2) A heat-sealed area and an isolation area are divided on the reverse side of the tissue paper, and the heat-sealed area is intermittently distributed along the edge contour of the isolation area; (3) Printing isolation oil on the isolation area and printing a pattern on the front side of the tissue paper; (4) folding the tissue paper along a preset fold line so that the reverse sides of the tissue paper are brought closer together and the heat-sealed areas are in contact with each other; (5) The heat-sealed area is subjected to heat-pressing treatment so that the heat-sealed area is bonded by heat-sealing oil, and the tissue paper forms a structural member with an opening.

[0007] Furthermore, in step (6), the structural member is die-cut to remove excess edge material to form a preset contour.

[0008] In the above technical solution, the fiber content of the cotton paper is ≥95wt%, and the cotton paper does not contain artificial synthetic fibers. Furthermore, the fiber content of the cotton paper is ≥98wt%. Preferably, the fiber content of the cotton paper is 98wt%.

[0009] In the above technical solution, the fiber length of the cotton paper is 20-40 mm, and the coefficient of variation of the fiber length is ≤15%. Furthermore, the fiber length of the cotton paper is 25-35 mm, and the coefficient of variation of the fiber length is ≤10%. Preferably, the fiber length of the cotton paper is 30 mm, and the coefficient of variation of the fiber length is ≤5%.

[0010] In the above technical solution, in step (1), the heat sealing oil is a water-based heat sealing coating, and the water-based heat sealing coating contains acrylic resin or ethylene-vinyl acetate copolymer.

[0011] In the above technical solution, in step (2), the isolation oil is a UV curing coating, and the UV curing coating contains acrylic resin or polyurethane acrylate.

[0012] In the above technical solution, in step (3), the isolation oil and pattern are formed by screen printing or flexographic printing.

[0013] In the above technical solution, in step (4), the preset fold line is located in the middle of the tissue paper, and the heat-sealing area is symmetrically distributed along the preset fold line axis.

[0014] In the above technical solution, in step (5), the heat sealing temperature of the hot pressing treatment is 150-200°C, and the heat sealing time is 1-3 seconds. Preferably, the heat sealing temperature is 180±5°C, and the heat sealing time is 2±0.5 seconds.

[0015] In the above technical solution, in step (5), the structural member is a bag, box, sleeve, tube, or cylinder. It should be noted that the shape of the structural member can be determined according to the shape of the electronic device, such as a bag for a mobile phone, a box for a laptop, a sleeve for a selfie stick, and a cylinder for a speaker. The structural member can be formed by properly setting the preset fold lines and folding them.

[0016] In the above technical solution, the step (1) may further include a step of pre-treating the tissue paper, wherein the pre-treatment is dipping the tissue paper in a waterproofing agent or a wear-resistant agent.

[0017] An electronic device packaging and protection structural component is manufactured by the aforementioned method for manufacturing an electronic device packaging and protection structural component, comprising a structural component formed by folding cotton paper; the reverse side of the cotton paper is divided into a heat-sealing area and an isolation area, the heat-sealing areas being intermittently distributed along the edge contour of the isolation area; the heat-sealing area and the isolation area are both coated with heat-sealing oil, and the isolation oil surface of the isolation area is printed with isolation oil; the cotton paper is folded, the heat-sealing area is affixed and heat-sealed, so that the cotton paper forms a structural component with an opening; and the front side of the cotton paper is printed with a pattern.

[0018] By adopting the above technical solution, the beneficial effects of the present invention are: (1) Use cotton paper as the substrate. The higher the fiber content of the cotton paper, the better the biodegradability. The fiber content of cotton paper ≥95wt% can ensure the high biodegradability of the cotton paper and make it meet the requirements of environmental protection regulations.

[0019] (2) If the fibers of cotton paper are too long, they may become too hard and easily creased when folded. If they are too short, they may be too soft, difficult to shape, and easy to fall off. The fiber length of cotton paper should be 20-40 mm, which can not only ensure sufficient interweaving strength and maintain flexibility to avoid scratching the surface of electronic devices, but also reduce fiber shedding and prevent cotton paper fibers from adhering to the surface of electronic devices (such as screens, cameras and other precision components), ensuring the cleanliness of the products when they leave the factory.

[0020] (3) The use of water-based heat-sealing coatings and UV-curing isolation oils reduces volatile organic compound emissions, making the production process more environmentally friendly.

[0021] (4) The heat-sealing oil and isolation oil on the reverse side form a continuous protective film, which not only keeps the cotton paper flexible and has support, but also effectively prevents the cotton paper fibers from falling off and adhering to the surface of electronic equipment (such as screens, cameras and other precision parts), ensuring the cleanliness of the product when it leaves the factory.

[0022] (5) By designing the reverse heat-sealing area and the isolation area, combined with the folding and hot pressing process, the production process is simplified and production efficiency is improved.

[0023] (6) It can be folded into structural parts of different shapes according to the shape of the product to meet the packaging requirements of various electronic devices.

[0024] (7) According to the packaging requirements of the product, pretreatment steps (waterproof and wear-resistant) can be added, and a composite coating of heat sealing oil and isolation oil can be combined to further improve the adaptability of structural parts to complex transportation environments such as moisture and friction, thereby extending their service life.
