Abstract
Description
Technical Field
[0001] The utility model relates to an anti-mildew product, and in particular to a plastic-free anti-mildew sheet. Background Art
[0002] In many humid and warm environments, how to effectively prevent food, leather and other items from getting moldy is a common goal for many people. The current mold prevention technology generally places chemical agents such as preservatives, desiccants or deoxidizers in containers to inhibit or prevent the growth of mold. However, if these agents are applied to food, the chemical agents may affect human health, so there is still a need for improvement.
[0003] At present, there are anti-mildew and deodorant sheets adsorbed with anti-mildew essential oils on the market. Figure 1 As shown, the existing mildew-proof and deodorizing sheet comprises an OPP (Oriented Polypropylene; uniaxially oriented polypropylene) film 1, a coated paper 2 and a release paper 3, wherein the OPP film 1 and the coated paper 2 are bonded together by an acrylic adhesive layer 4, and the release paper 3 is attached to the side of the coated paper 2 away from the OPP film 1 through another acrylic adhesive layer 4, and the multiple acrylic adhesive layers 4 can absorb mildew-proof essential oil (not shown).
[0004] When using the mildew-proof and deodorizing sheet, you can choose whether to tear off the release paper 3 on the coated paper 2. If the release paper 3 is not torn off, the mildew-proof effect lasts longer because the mildew-proof essential oil of the acrylic adhesive layer 4 will not be released quickly. This is because the OPP film 1 and the release paper 3 can avoid the mildew-proof essential oil from being released quickly from the top and bottom, and achieve the effect of slow release of the mildew-proof essential oil. The mildew-proof essential oil adsorbed by the acrylic adhesive layer 4 will evaporate slowly from all sides.
[0005] To extend the usable time of the anti-mildew and deodorizing sheet, please refer to Figure 2 As shown, the mildew-proof and deodorizing sheet has a plurality of OPP films 1A, a coated paper 2A and a release paper 3A. The plurality of OPP films 1A and the coated paper 2A are bonded together by an acrylic adhesive layer 4A, and the release paper 3A and the coated paper 2A are bonded together by another acrylic adhesive layer 4A. The plurality of acrylic adhesive layers 4A can absorb mildew-proof essential oil (not shown). The release principle of this structure is the same as described in the previous paragraph, but because there are more acrylic adhesive layers 4A, more mildew-proof essential oil can be absorbed in principle.
[0006] Accordingly, more mildew-proof essential oil will slowly volatilize from the four sides of the mildew-proof essential oil adsorbed by the acrylic adhesive layer 4. Therefore, sufficient essential oil quantity and use time can be provided.
[0007] However, in the prior art, in order to use the OPP film 1, 1A to cover the acrylic adhesive layer 4, 4A layer to prevent the anti-mildew essential oil from volatilizing, the OPP film 1, 1A is a kind of polypropylene film, which is a common plastic material. When used in large quantities and not recycled, it will cause environmental harm. Utility Model Content
[0008] The utility model provides a plastic-free mildew-proof sheet, which does not need to use plastic materials and meets the use requirements of environmental protection and plastic-free.
[0009] The utility model provides a plastic-free mildew-proof sheet, comprising a first paper film, a first adhesive absorption layer, a base paper layer, a second adhesive absorption layer and a second paper film, wherein the base paper layer has a first surface and a second surface back to back, the first adhesive absorption layer is used for absorbing mildew-proof essential oil, and the two sides of the first adhesive absorption layer are respectively adhered to the first paper film and the first surface of the base paper layer, the second adhesive absorption layer is used for absorbing mildew-proof essential oil, and the two sides of the second adhesive absorption layer are respectively adhered to the second paper film and the second surface of the base paper layer.
[0010] In an embodiment of the present invention, the first paper film and the second paper film are transparent, and one of the first paper film and the second paper film is printed with a graphic or text.
[0011] In an embodiment of the present invention, the first paper film and the second paper film are natural fiber films.
[0012] In an embodiment of the present invention, the base paper layer is coated paper.
[0013] Based on the above, the first paper film, the second paper film and the base paper layer can be made of paper materials. Furthermore, the base paper layer can use recycled coated paper.
