Problems solved by technology

However, most volatile antibacterial agents have poor thermal stability, which limits their use in antibacterial packaging.
[0003] Existing antibacterial packaging film materials cannot slowly release antibacterial ingredients to achieve a lasting antibacterial effect, and cannot have good mechanical properties at the same time, and cannot be mass-produced

Embodiment 1

[0033]Such asFigure 1-2As shown, the sustained release of the present embodiment includes an outer sustained release antibacterial layer 1, a first barrier layer 2, an intermediate film layer 3, a second barrier layer 4, and a second barrier layer 5, from the outer to the outer to the outer to inward. The inner bucket of the antibacterial layer 5 is prepared from the weight of the following weight of the material: 85 parts of metallocene polyethylene resin, 18 parts of high density polyethylene resin, 35 cyclodextrin-essential oil classes, plasticizer 11 parts of alcohol, 8 servine sulfate. The first barrier layer 2, the second barrier layer 4 is prepared from a linear low density polyethylene resin with a high density polyethylene resin to be prepared according to 2.5: 1.

[0034]The method of preparing the cyclodextrin-essential oil clamper is as follows: β-cyclo paste is dissolved in distilled water, stir evenly to obtain a concentration of 5.2% by weight of β-cyclo-cyclo-hydrazine ...

Embodiment 2

[0041]Such asFigure 1-2As shown, the sustained release of the present embodiment includes an outer sustained release antibacterial layer 1, a first barrier layer 2, an intermediate film layer 3, a second barrier layer 4, and a second barrier layer 5, from the outer to the outer to the outer to inward. The inner bucket of the antibacterial layer 5 is prepared from the weight of the following weights: 83 parts of metallocene polyethylene resin, 17 high density polyethylene resins, 34 cyclodextrin-essential oil clam, plasticizer glucose 10 parts, 9 sodium lignozoate sodium sulfate. The first barrier layer 2, the second barrier layer 4 is prepared from a linear low density polyethylene resin with a high density polyethylene resin to be prepared according to 2.5: 1.

[0042]The method for preparing the cyclodextrin-essential oil clamper is as follows: β-cyclo paste is dissolved in distilled water, stir evenly to obtain a concentration of 5.2% by weight of β-cyclodecycle water solution, 60 °...

Embodiment 3

[0049]Such asFigure 1-2As shown, the sustained release of the present embodiment includes an outer sustained release antibacterial layer 1, a first barrier layer 2, an intermediate film layer 3, a second barrier layer 4, and a second barrier layer 5, from the outer to the outer to the outer to inward. The inner bucket of the antibacterial layer 5 is prepared from the weight of the following weight of the material: 86 parts of metallocene polyethylene resin, 18 parts of high density polyethylene resin, 35 cyclodextrin-essential oil clades, plasticizer glycerol 12 serviles, 9 serves sodium lignozoate. The first barrier layer 2, the second barrier layer 4 is prepared from a linear low density polyethylene resin to high density polyethylene resin.

[0050]The method for preparing the cyclodextrin-essential oil clam is as follows: β-cyclo paste is dissolved in distilled water, stir evenly to obtain a concentration of 6 wt% β-cyclo-cyclo-hydrazine solution, 60 ° C water bath heating 12min, n...

Abstract

The invention provides a slow-release antibacterial packaging material and a preparation method thereof, and relates to the technical field of packaging materials. The slow-release antibacterial packaging material comprises an outer slow-release antibacterial layer, a first barrier layer, a middle film layer, a second barrier layer and an inner slow-release antibacterial layer from outside to inside; the preparation method comprises the steps: preparing the outer slow-release antibacterial layer material, preparing the inner slow-release antibacterial layer liquid, and casting to form the film. According to the slow-release antibacterial packaging material, the first barrier layer and the second barrier layer enable the packaging material to maintain impact resistance, flexibility and ductility, and after the packaging material covers the outer surfaces of food, fruits and vegetables, the outer slow-release antibacterial layer adsorbs and removes external harmful gases such as ethylene, formaldehyde and sulfide; a cyclodextrin-essential oil clathrate compound in the inner slow-release antibacterial layer slowly releases volatile essential oil molecules to adsorb and remove internal harmful gas and maintain the aroma of fruits and vegetables, and the slow-release antibacterial packaging material has lasting and efficient antibacterial performance and good mechanical properties.

Description

Technical field[0001]The present invention relates to the technical field of packaging materials, and more particularly to a sustained release antibacterial packaging material and a preparation method thereof.Background technique[0002]Antibacterial packaging can be divided into: release, curable and absorption type depending on the antibacterial. The antibacterial agent in the release of antibacterial packaging can inhibit the growth of microorganisms, sterilization, efficiency, and relatively non-released antibacterial packaging, relatively non-released antibacterial packages, relatively non-released antibacterial packages, relatively non-released antibacterial packages. Inside the packaging system, such packaging materials do not need to be directly contacted with food, which can achieve the ideal bactericidal effect; in which antibacterial packages in which sustained release properties can form long-term sterilization, compared to short-time sterilization, most of the test microo...
