Problems solved by technology

After the packaging material is air-permeable and wine-permeable by acupuncture, the edge of the small package has needle-punched holes, and the tear strength decreases. At the same time, due to mechanical instability, it is not only difficult to control the depth of the holes punched in the packaging paper, but also After the final packaging material is rolled or overpressurized, it is difficult to control the re-sewing of the hole, which eventually leads to an unstable volatilization rate of alcohol. In this case, if the volatilization rate of alcohol is too high, it will definitely affect the flavor of the food. Small, it will definitely affect the fresh-keeping effect of the alcohol preservative. Secondly, the carrier of the alcohol will gradually dry out with the continuous volatilization of the alcohol, and it is very easy to leak from the pinhole, which will contaminate the preserved food; in addition, if The package contains color substances that can

Example Embodiment

[0023] Example one:

[0024] Reference figure 1 , Provide an alcohol preservative packaging paper, which is formed by laminating a surface layer of base paper and a plastic film layer, wherein the plastic film layer is made of a thermoplastic material selected from polyolefins and their mixtures or copolymers. The plastic film layer is a microporous film formed by microporous treatment during the manufacturing process.

[0025] The plastic film layer can use one or a mixture of the following plastics with heat sealing properties as the substrate: ethylene vinyl acetate, ethylene ethyl acrylate, ethylene acrylic acid, linear low-density polyethylene, high-density polyethylene, polyolefin plastic, Polyvinyl alcohol, polyacrylonitrile, ethylene-propylene elastomer mixture; and one or more fillers of the following substances with an average particle size of about 0.1-10 microns are added during the production process to stretch to produce uniform micropores , Water-permeable, air-per...

Example Embodiment

[0028] Embodiment two:

[0029] Reference figure 2 , Smear the glue on the virgin paper layer, then compound it with the microporous membrane made by the above method, and finally shape it, and the rest is the same as in Example 1.

Example Embodiment

[0030] Embodiment three:

[0031] Reference image 3 The alcohol preservative packaging paper is also formed by laminating a surface layer of base paper and a plastic film layer. The plastic film layer is a perforated film formed by direct blanching and needle punching during the production process.

[0032] The perforated film also uses one of the following plastics with heat sealing properties or a mixture thereof as a substrate: ethylene vinyl acetate, ethylene ethyl acrylate, ethylene acrylic acid, linear low density polyethylene, high density polyethylene, poly Olefin plastic, polyvinyl alcohol, polyacrylonitrile, ethylene-propylene elastomer mixture.

[0033] Take the following preparation methods:

[0034] Perform hot blanching or needle punching treatment on the plastic film layer to make a perforated film. At the same time, apply glue on the virgin paper layer, then combine the two, and finally shape.

[0035] Reference Figure 4 , Perform hot blanching or needle punching ...

Abstract

The invention discloses an alcohol antistaling agent wrapping paper aiming to provide the alcohol antistaling agent wrapping paper which has stable alcohol volatilizezing speed, is not lead or penetrate and has low cost and a preparation method thereof. The wrapping paper is formed by jointing a base paper layer on the surface layer and a plastic film layer, wherein, the plastic film layer is made of a material which has thermoplasticity and is selected from the polyolefine or the mixture of the polyolefine or a multipolymer, the plastic film layer is a microporous film formed by the microporous treatment in the manufacturing process, or is punching film which is formed by the direct blanching and pinprick processes in the manufacturing process.

Description

technical field [0001] The technical field of the alcohol antistaling agent of the present invention, in particular relates to an alcohol antistaling agent wrapping paper and a preparation method thereof. Background technique [0002] The packaging materials for alcohol preservatives are required to be air-permeable, able to slowly pass through a small amount of alcohol in a certain period of time, not to leak, and have a certain strength. There are three types of packaging materials for alcohol preservatives currently used: [0003] (1) Paper-plastic composite packaging paper; [0004] (2) plastic composite packaging paper; [0005] (3) Wrapping paper made of paper, a layer of perforated plastic film, and a bottom layer of plastic mesh. [0006] Paper-plastic composite packaging paper is made of plant fiber or chemical fiber paper (abbreviated as base paper) and plastic composite, plastic-plastic composite packaging is composite of two different materials of plastic, both...
