Technical Field

[0001] The utility model belongs to the technical field of humidity-conditioning sheets, and in particular relates to a self-adhesive humidity-conditioning sheet for a container. Background Art

[0002] Humidity control sheets are used to adjust the humidity inside canned, bottled or box containers to control the storage humidity of the contents in the canned or bottled containers and thus protect the contents.

[0003] In the related art, a humidity conditioning sheet is directly placed in a container to contact the items in the container. The printed ink on the humidity conditioning sheet easily contacts the items in the container and takes up space. Utility Model Content

[0004] The purpose of the utility model is to provide a self-adhesive humidity-conditioning sheet for a container, so as to solve the problem in the related art that the printing ink on the humidity-conditioning sheet easily contacts the items in the container and occupies space.

[0005] To this end, the utility model provides a self-adhesive humidity-regulating sheet for a container, comprising: a packaging film and a moisture-permeable film, wherein a humidity-regulating material is coated between the packaging film and the moisture-permeable film, and a connecting layer is provided on one side of the packaging film, wherein the connecting layer is used to connect the packaging film to the inner wall of the container.

[0006] Preferably, the material of the connecting layer is a pressure-sensitive adhesive, through which the packaging film can be directly attached to the top or side wall of the container.

[0007] Preferably, the connecting layer is covered with a protective layer.

[0008] Preferably, the protective layer is release paper.

[0009] Preferably, the humidity-conditioning material is a paper sheet.

[0010] Preferably, the paper sheet has a humidity-controlling liquid adsorbed thereon. The humidity-controlling liquid adsorbed by the paper sheet serves to control humidity. Furthermore, the humidity-controlling liquid is preferably glycerol or propylene glycol, which can absorb moisture from the air.

[0011] Preferably, the humidity-controlling material is a humidity-controlling gel. A further preferred humidity-controlling gel is a gel made of calcium chloride or lithium chloride, which can release moisture when the ambient humidity is low and absorb moisture when the ambient humidity is high, thereby controlling the humidity.

[0012] Preferably, the humidity-controlling material is a humidity-controlling liquid. More preferably, the humidity-controlling liquid is glycerin or propylene glycol, which can absorb moisture from the air.

[0013] Preferably, the material of the moisture-permeable membrane is one of PVA, PTFE, PE, and OPP.

[0014] Preferably, the material of the packaging film is one of PE, PP, PLA, and EVOH.

[0015] Beneficial effects:

[0016] 1. The utility model provides a self-adhesive humidity-conditioning sheet for a container. The humidity inside the container is regulated by the humidity-conditioning material in the packaging film and the moisture-permeable film passing through the moisture-permeable film. The humidity-conditioning sheet can be attached to the top or side wall of the container via a connecting layer to avoid direct contact with the product inside the container and does not occupy storage space inside the container. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0018] Figure 1 This is a schematic structural diagram of a self-adhesive humidity-conditioning sheet for a container provided by the utility model.

[0019] Figure 2 This is a cross-sectional view of a self-adhesive humidity-conditioning sheet for a container provided by the utility model.

[0020] In the figure, 1- packaging film, 2- moisture permeable film, 3- humidity regulating material, 4- connecting layer, 5- protective layer. DETAILED DESCRIPTION

[0021] The present invention can be more easily understood by referring to the following detailed description of the preferred embodiments of the present invention and the included Examples. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as commonly understood by one of ordinary skill in the art to which the present invention belongs. In the event of any conflict, the definitions in this specification shall prevail.

[0022] Example 1:

[0023] Provides the following for completion Figure 1-2The self-adhesive humidity-regulating sheet for containers shown in the figure comprises a packaging film 1 and a moisture-permeable film 2, with a humidity-regulating material 3 coated between the packaging film 1 and the moisture-permeable film 2. A connecting layer 4 is provided on one side of the packaging film 1, which is used to connect the packaging film 1 to the inner wall of the container. The connecting layer 4 is made of a pressure-sensitive adhesive, which allows the packaging film 1 to be directly attached to the top or side wall of the container. The connecting layer 4 is covered with a protective layer 5, which is a release paper. When not in use, the protective layer 5 protects the connecting layer 4. When in use, the protective layer 5 is removed, and the packaging film 1 is connected to the top or side wall of the container via the connecting layer 4. The moisture-permeable film 2 is made of PE. The packaging film 1 is made of PLA.

[0024] The humidity-conditioning material 3 in this embodiment is a paper sheet. A humidity-conditioning liquid, which is propylene glycol, is adsorbed on the paper sheet. The paper sheet adsorbs the humidity-conditioning liquid to achieve humidity control, absorbing moisture from the air.

[0025] Example 2:

[0026] The difference between Example 2 and Example 1 is that the humidity-controlling material 3 in this example is a humidity-controlling gel, which is a gel made of lithium chloride. It can release moisture when the ambient humidity is low and absorb moisture when the ambient humidity is high, thereby playing a role in humidity control.

[0027] Example 3:

[0028] The difference between Example 3 and Example 1 is that the humidity-controlling material 3 in this example is a humidity-controlling liquid, and the humidity-controlling liquid is glycerin, which can absorb moisture from the air.

[0029] Working Principle: Packaging film 1 and moisture-permeable film 2 enclose humidity-regulating material 3. Water vapor within the container is exchanged with the humidity-regulating material 3 through the moisture-permeable film 2, thereby regulating the humidity within the container. When not in use, protective layer 5 protects connecting layer 4. When in use, protective layer 5 is removed, and packaging film 1 is connected to the top or side wall of the container via connecting layer 4.
