Alcohol antistaling agent wrapper paper and method for making same

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...

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 be dissolved in water, alcohol, oil, etc. During the production, storage and use of alcohol preservatives, the color substances will penetrate into the alcohol preservatives with water, alcohol, oil and other media to pollute the fresh-keeping products. food

[0007] The three-layer packaging paper made of paper, perforated plastic film layer and bottom plastic mesh layer is commonly known as "network paper" in the market. performance, it can be used as a material for alcohol preservatives, but because this packaging material uses expensive plastic mesh to enhance the strength of the packaging material, the current market price of this kind of packaging material is quite expensive, and it will undoubtedly be greatly improved when used in alcohol preservatives. It increases the production cost of the manufacturer, and the additional use of plastic net layer does not show obvious advantages in enhancing the strength of the alcohol preservative packaging material
