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...
