Embodiment 1

[0043] A method for preparing a food vacuum fresh-keeping compression bag, the food vacuum fresh-keeping compression bag is composed of an aluminum foil bottom layer and a polyethylene coating layer;

[0044] The aluminum foil bottom layer is composed of 45% aluminum powder, 25% polyethylene resin, 15% nanometer powder, 10% glyceryl monostearate, 3% paraffin oil and 2% bamboo charcoal particles by weight percentage; Nano-powder is made by mixing nano-silica powder, nano-titanium dioxide powder and nano-zinc oxide powder according to the weight percentage of 3:1:1;

[0045] The polyethylene coating consists of 40% polyethylene resin, 15% phenolic resin, 15% polyurethane resin, 15% glycerol, 10% calcium stearate and 5% 2-hydroxy - Composition of 4-methoxybenzophenone;

[0046] And the preparation method of the food vacuum preservation compression bag comprises the following steps:

[0047] 1) Preparation of the bottom layer of aluminum foil: first introduce aluminum powder int...

Embodiment 2

[0052] A kind of preparation method that is used for food vacuum fresh-keeping compressed bag, and the difference in embodiment 1 is, without nano-powder and composition thereof; It consists of polyethylene resin, 15% glyceryl monostearate, 3% paraffin oil and 2% bamboo charcoal particles, and step 1) does not involve the participation of nanometer powder in the preparation process of the aluminum foil bottom layer.

Embodiment 3

[0054] A kind of preparation method that is used for food vacuum fresh-keeping compressed bag, and the difference in embodiment 1 is that there is no 2-hydroxyl-4-methoxybenzophenone; that is, the polyethylene coating is divided by weight percentage It consists of 40% polyethylene resin, 15% phenolic resin, 15% polyurethane resin, 15% glycerol and 15% calcium stearate, and there is no Involvement of 2-hydroxy-4-methoxybenzophenone.

Abstract

The invention discloses a preparing method used for a food vacuum freshness retaining compression bag. The food vacuum freshness retaining compression bag is composed of an aluminum foil bottom layer and polyethylene coating. The aluminum foil bottom layer is composed, by weight percent, 45% of aluminum powder, 25% of polyethylene resin, 15% of nanopowder, 10% of glycerin monostearate, 3% of paroline and 2% of bamboo charcoal particles; the nanopowder is formed through blending of nanosilicon dioxide powder, nanometer titania powder and nano-zinc oxide powder according to the weight percent of 3:1:1; through combination of the ultraviolet shielding effect of the nanopowder in the aluminum foil bottom layer and ultraviolet absorbing effect of 2-hydroxide radical-4-methoxybenzophenone in the polyethylene coating, the food vacuum freshness retaining compression bag can be sufficiently protected, and the conditions that under long-term light irradiation, color is prone to changing, embrittlement is prone to happening, the packaging food goes bad, and the use effect is greatly affected are avoided.

Description

technical field [0001] The invention relates to the technical field of compressed bags, in particular to a method for preparing compressed bags used for vacuum preservation of food. Background technique [0002] Vacuum compression bags are a type of packaging bags that take out the air and let the atmospheric pressure cause natural compression. It is mainly used for packaging quilts, clothing and food, etc., and has the characteristics of moisture-proof, mildew-proof, moth-proof and odor-proof. [0003] And in the document of patent No. CN105034511B, CN105252840B, all is earlier that two parts diaphragms are cut into shape, then take away and make bag with machine heat sealing, pack and roll at last, to make vacuum compression bag, and in and present Combining the preparation process of some food vacuum preservation compression bags, there are still cumbersome operations and multiple handling labors, which makes it difficult to achieve the overall continuous work, which gre...
