Description

Technical Field

[0001] The utility model relates to an anti-mildew product, and in particular to a material-saving 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 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 coated paper 2 and the release paper 3 are also bonded together by an 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 absorbed by the acrylic adhesive layer 4 penetrates the coated paper 2 and evaporates slowly from the four sides of the coated paper 2.

[0005] To extend the service life 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 also bonded together by an 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] Therefore, the anti-mold essential oil not only evaporates slowly through the coated paper 2A, but also evaporates from the gaps between the multiple layers of the OPP film 1A, thus providing a sufficient service life. However, the multiple layers of the OPP film 1A require the use of more plastic materials (OPP film 1A) and cannot meet the use of recycled materials ratio required by the EU GRS (Global Recycle Standard) regulations, nor can it meet the environmental protection needs of reducing plastic. Utility Model Content

[0007] The utility model provides a material-saving mildew-proof sheet, which can provide mildew-proof sheets with the same service life while saving material usage, so as to meet the use requirements of environmental protection and plastic reduction.

[0008] The utility model provides a material-saving mildew-proof sheet, comprising an OPP (Oriented Polypropylene) film, a first adhesive absorption layer, a PE (Polyethylene) film, a second adhesive absorption layer and a transparent PET (Polyethylene Terephthalate) release film. The first adhesive absorption layer and the second adhesive absorption layer are used to absorb mildew-proof essential oil, and the two sides of the first adhesive absorption layer are respectively adhered to the OPP film and the PE film, and the two sides of the second adhesive absorption layer are respectively adhered to the transparent PET release film and the PE film.

[0009] In an embodiment of the present invention, the first adhesive absorption layer is acrylic glue.

[0010] In an embodiment of the present invention, the second adhesive absorption layer is acrylic glue.

[0011] Based on the above, the PE film and the transparent PET release film of the utility model have the characteristic of high density, and the anti-mildew essential oil adsorbed by the first and second adhesive adsorption layers can only evaporate from the edges, achieving a slow release effect. Compared with the conventional anti-mildew sheet using coated paper, it can provide the same service life without using multiple layers of OPP film, and can meet the use requirements of environmental protection and plastic reduction.

[0017] The above and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of a preferred embodiment with reference to the accompanying drawings. The directional terms mentioned in the following embodiments, such as up, down, left, right, front or back, etc., are only referenced to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and not to limit the present invention.

[0018] See also Figure 3 and Figure 4 As shown, the utility model provides a material-saving anti-mildew sheet P, comprising an OPP film 10, a first adhesive absorption layer 20, a PE film 30, a second adhesive absorption layer 40 and a transparent PET release film 50. In one embodiment, the thickness of the OPP film 10 is 0.033 mm. The thickness of the PE film 30 is 0.11 mm. The thickness of the transparent PET release film 50 is 0.012 mm. The PE film 30 can be made of recycled PE (Polyethylene), and the transparent PET release film 50 is made by coating a release agent on PET.

[0019] The first adhesive absorption layer 20 and the second adhesive absorption layer 40 are used to absorb mildew-proof essential oil. The first adhesive absorption layer 20 and the second adhesive absorption layer 40 can be acrylic glue, and the two sides of the first adhesive absorption layer 20 are respectively adhered to the OPP film 10 and the PE film 30, and the two sides of the second adhesive absorption layer 40 are respectively adhered to the transparent PET release film 50 and the PE film 30.

[0020] See also Figure 5 As shown, in practice, in order to simultaneously produce a plurality of the material-saving anti-mildew sheets P, a saddle seam S is provided between different material-saving anti-mildew sheets P. When the material-saving anti-mildew sheet P is to be used, it is only necessary to tear it along the saddle seam S to obtain a single material-saving anti-mildew sheet P. The material-saving anti-mildew sheet P will slowly release the anti-mildew essential oil to produce an anti-mildew effect.

[0021] The PE film and the transparent PET release film of the utility model have the characteristic of high density, so the mildew-proof essential oil adsorbed by the first and second adhesive adsorption layers can only volatilize from the edges, thereby achieving a slow release effect.

[0022] Compared with the prior art, the present invention has at least the following features:

[0023] 1. The utility model is a new type of material-saving anti-mildew sheet. Compared with the conventional anti-mildew sheet using coated paper, it can provide the same service life without using multiple layers of OPP film, so that the usage ratio of the OPP film and the PE film complies with the EU GRS (Global Recycle Standard) and global recycling standard regulations to meet the use needs of environmental protection and plastic reduction.

[0024] Second, the PE film used has the characteristic of high density, which can allow the anti-mildew essential oil adsorbed by the first adhesive absorption layer and the second adhesive absorption layer to evaporate slowly from the edge, effectively reducing the usage of the anti-mildew essential oil.

[0025] The utility model has been described in detail above, but the above is only a preferred embodiment of the utility model and should not limit the scope of implementation of the utility model. That is, all equivalent changes and modifications made according to the scope of application of the utility model should still fall within the scope of the patent of the utility model.
