Description

Moldproof bag

The present invention relates to a packaged article for providing storage and preservation of articles, and more particularly to a moldproof and fresh-keeping bag which has the function of preventing mildew, preventing bacteria and keeping fresh.

In daily life, in order to properly store objects or food, people usually use plastic bags or zipper bags to pack objects or food, so that objects or food are isolated from the outside air, so as to achieve dustproof, antifouling and preservation. .

The plastic bags or zipper bags that are currently used to store objects or foods are generally made of plastic materials (such as PE film) or aluminum foil film, which are made of anti-mold and fresh-keeping bags. Or the food can only provide a closed and isolated preservation function. There is no way to prevent or inhibit the growth of microorganisms or molds, so that the objects or foods are easily damaged or deteriorated during the preservation process due to the growth of microorganisms or molds. In order to solve the anti-mildew problem of the preservation of objects or foods, people usually put an anti-mold bag or a fresh-keeping bag in the bag, and the anti-mold bag or the fresh-keeping bag has a chemical agent in the form of granules or powder. Chemical agents produce mildew and bacteriostatic effects.

However, placing a mold-proof bag or a fresh-keeping bag in a plastic or aluminum foil packaging bag not only utilizes a high cost, but also increases the processing trouble when packaging, and if the user does not pay attention, accidental ingestion may occur. problem. In particular, the existing anti-mold bag or fresh-keeping bag is made of chemical agent to produce anti-mildew and antibacterial action. If the anti-mold bag or the fresh-keeping bag inadvertently ruptures during production, transportation or use, chemistry will occur. Serious pollution There is a need to study and improve.

In order to solve the shortage and limitation of the plastic or aluminum foil packaging bag, the main purpose of this creation is to propose a moldproof fresh-keeping bag with anti-mildew and anti-bacteria and fresh-keeping effect, which is a flexible piece for the mold-proof fresh-keeping bag. The body adsorption contains a natural antifungal composition which can be volatilized and released, and can be slowly released during use to produce an anti-mildew and antibacterial effect, thereby effectively solving the problem of the preservation function of the existing packaging bag lacking anti-mildew and antibacterial.

The present invention solves the problem of the prior art, which is formed by a flexible sheet and is internally formed with an accommodating space. The flexible sheet comprises: a substrate, which is a film. a sheet-like material; a protective film disposed on the outer side of the substrate; and one or more adsorption films bonded to the inner side of the substrate, which have gas permeable characteristics and internally adsorb the natural antifungal composition containing the volatile release .

The anti-mold preservation bag, wherein a printing layer is disposed between the substrate and the protective film, and the printing layer is printed or bonded in a partial or comprehensive manner.

The anti-mold preservation bag, wherein the adsorption film is arranged in two layers in a stack in the substrate.

The enhancements to the technical means proposed by this creation include:

1. This product is designed to absorb the natural anti-mildew composition containing volatile release in the flexible sheet, effectively using the most streamlined structure design and low cost, so that the mold-proof fresh-keeping bag has the function of anti-mildew and anti-bacteria and preservation. Economically beneficial.

2. The present invention directly adsorbs the natural anti-mold composition containing volatile release, and can complete the packaging and preservation work of the object or food without adding packaging steps.

3. The natural anti-mildew composition of the present invention is obtained by using a variety of natural plant extracts, which are obtained by blending, standing fermentation and filtration, and can effectively decompose odor molecules and inhibit the growth of microorganisms such as molds and bacteria, comply with environmental protection requirements and avoid Chemical substances harm the human body.

The mold-resistant fresh-keeping bag 10 is formed by a flexible sheet body 11 and defines an accommodating space 12 therein. The space 12 has a bag opening 121 that can communicate with the outside, and a zipper 13 that can close the mold-proof bag is disposed at the position of the bag opening 121, and various objects or foods such as a CD can be stored in the accommodating space 12 . Inside. The above is the basic structural design of the existing general zippered bag body, and the details are not described in detail.

Referring to the first preferred embodiment of the flexible sheet 11 shown in FIG. 1 and FIG. 3 , the flexible sheet 11 includes a substrate 111 and a printing printed on the outside of the substrate 111 . a layer 112, a protective film 113 bonded to the outside of the substrate 111, and an adsorption film 114 bonded to the inner side of the substrate 111 (ie, the side facing the accommodating space 12); wherein: the substrate 111 is an aluminum foil Or a film-like sheet material such as a film; The printing layer 112 is printed on the outer side of the substrate 111 in a comprehensive or partial manner, and the pattern may be a logo, a background pattern or a description of the use, etc., and the creation is not particularly limited, and the printing layer is not specifically limited. 112 may be omitted and need not be provided; the protective film 113 is a plastic film disposed on the outer side of the substrate 111, and the substrate 111 and the printed layer 112 can be protected. The protective film 113 can be a PE film or have a high The OPP film (polypropylene film) which is resistant to stretching, light, non-toxic, tasteless and environmentally-friendly, is not specifically limited in this creation; the adsorption film 114 of the one layer or more is bonded to the inside of the substrate 111, and The adsorption film 114 is a plastic film with gas permeable characteristics and internally adsorbs a natural antifungal composition containing a volatile release. The natural antifungal composition is mainly selected from freely extracted garlic oil, tea tannin, and camphor oil. Ginger oil, mustard powder, citronella, jasmine essence and activated carbon and alcohol solution are prepared by mixing, standing fermentation and filtration, and using soaking or volatile vapor adsorption, etc. In a manner, the natural antifungal composition is attached to the inside and the surface layer of the adsorption film 114. The embodiment shown in FIG. 3 is an embodiment in which two adsorption layers 114 are disposed in a stacking manner. Preferably, The adsorption film 114 is an OPP film having high tensile strength, light weight, non-toxic and tasteless, and environmentally-friendly characteristics.
