The mildew-proof component on the adsorption layer can pass through the one-way breathable film to diffuse and volatilize outwards, so that the mildew-proof bag can be used for preventing and resisting bacteria for food and the like for a long time. As the mildew-proof component is diffused from the inside to the outside of the package in a one-way manner, the mildew-proof component can be uniformly and stably released to the outside, the mildew-proof effect of the product is enhanced, and the shelf life can be prolonged.
Preferably, the outer package comprises an interlayer formed by bonding two layers of unidirectional breathable films, and the adsorption layer is arranged in the interlayer. The structure is beneficial to production and processing, and the adsorption layer can be simply arranged in the interlayer.
Preferably, the adsorption layer is made of degradable paper. The degradable paper can adsorb mildew-proof components and is favorable for decomposition and reuse. The adsorption layer contributes to environmental protection.
Preferably, the adsorption layer adopts a porous structure. The paper with the porous structure is beneficial to adsorbing more mildew-proof components and enhancing the mildew-proof effect.
Preferably, the mold resistant component comprises a biologically active peptide. It can inhibit the growth of mould by penetrating the mould cell membrane, destroying DNA, decomposing protein, and the small molecule form is more favorable for diffusion. For example, the bioactive peptide is extracted from natural plants such as mustard.
Preferably, the mildew-proof component further comprises mint essential oil and cassia oil. These two additives help to regulate the odor and enhance the mold-proofing effect.
Preferably, the one-way ventilated membrane comprises a separation film, a waterproof coating and a base material, the separation film is arranged on the outer side of the waterproof coating, the base material is arranged on the inner side of the waterproof coating, the separation film is made of a polypropylene material, a plurality of air holes are distributed on the outer surface of the separation film, the air holes are unevenly or uniformly distributed, and the aperture of the air holes is gradually increased from outside to inside. The pore diameter change of the air holes is beneficial to one-way ventilation, so that active ingredients volatilized by the adsorption layer are slowly released to the outside of the outer package, and the influence of substances such as external moisture on the adsorption layer is reduced.
Preferably, the peripheries of the two unidirectional breathable films are bonded, so that the unidirectional breathable films are spliced to form the interlayer. The periphery of the unidirectional breathable film is directly bonded, so that the quantitative production is facilitated.
Preferably, the unidirectional breathable film is further coated with a PE film. The PE film is coated on the outer surface of the outer package, so that the periphery of the unidirectional breathable film can be prevented from tilting and falling off, and the bonding is tighter.

Detailed Description
The technical solution of the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
Example 1
Referring to fig. 1 to 4, the mildewproof bag comprises an outer package 100 and an adsorption layer 200, wherein the outer package 100 wraps the adsorption layer 200, and the adsorption layer 200 is attached with a mildewproof component; the package 100 includes a one-way gas permeable membrane to allow the evaporative diffusion of the mold resistant composition from within the package 100 to outside the package 100.
The outer package 100 comprises an interlayer 130 formed by bonding two unidirectional breathable films 110 and 120, and the adsorption layer 200 is arranged in the interlayer 130. Such a configuration facilitates manufacturing processes and also allows for a simple placement of the absorbent layer 200 within the interlayer 130.
The adsorption layer 200 is made of degradable paper. The degradable paper can adsorb mildew-proof components and is favorable for decomposition and reuse. The absorbent layer 200 contributes to environmental protection.
The adsorption layer 200 adopts a porous structure. The paper with the porous structure is beneficial to adsorbing more mildew-proof components and enhancing the mildew-proof effect.
The mildew-resistant component comprises a bioactive peptide. It can inhibit the growth of mould by penetrating the mould cell membrane, destroying DNA, decomposing protein, and the small molecule form is more favorable for diffusion.
The mildew-proof component also comprises mint essential oil and cassia oil. These two additives help to regulate the odor and enhance the mold-proofing effect.
The one-way breathable film 110 comprises a separation film 113, a waterproof coating 112 and a substrate 111, wherein the separation film 113 is arranged on the outer side of the waterproof coating 112, the substrate 111 is arranged on the inner side of the waterproof coating 112, the separation film 113 is made of a polypropylene material, a plurality of air holes are distributed on the outer surface of the separation film 113, the air holes are unevenly or uniformly distributed, and the aperture of the air holes is gradually increased from outside to inside. The pore size change of the ventilation holes is helpful for one-way ventilation, so that active ingredients volatilized from the adsorption layer 200 are slowly released to the outside of the outer package 100, and the influence of substances such as external moisture on the adsorption layer 200 is reduced.
The peripheries of the two unidirectional breathable films are bonded to form the interlayer 130 by splicing the unidirectional breathable films. The periphery of the unidirectional breathable film is directly bonded, so that the quantitative production is facilitated.
The unidirectional breathable film is also coated with a PE film 114. The PE film 114 is coated on the outer surface of the outer package 100 to prevent the periphery of the unidirectional breathable film from tilting and falling off, so that the bonding is tighter.
The mildew-proof package in the scheme can pass through the one-way breathable film through the mildew-proof components on the adsorption layer 200 to diffuse and volatilize outwards, so that mildew and bacteria can be prevented and prevented for a long time for food and the like. As the mildew-proof component is diffused from the inside to the outside of the package 100 in a single direction, the mildew-proof component can be uniformly and stably released to the outside, the mildew-proof effect of the product is enhanced, and the shelf life can be prolonged.
Variations and modifications to the above-described embodiments may occur to those skilled in the art, in light of the above teachings and teachings.
