Abstract

The invention belongs to the technical field of packaging, and concretely relates to a mildew inhibitor for liquor packaging cartons, and a preparation method thereof. The mildew inhibitor for liquorpackaging cartons comprises, by mass, 0.25-1.0% of sodium dehydroacetate, 0.005-0.02% of natamycin, and the balance of glue, and the sum of the mass percentages of all above components is 100%. The preparation method of the mildew inhibitor comprises the following steps: 1) weighing all the raw materials in proportion, and uniformly mixing the sodium dehydroacetate with natamycin; and 2) adding amixture obtained in step 1) to the glue for carton packaging. The mildew inhibitor can effectively prevent molds, has a high efficiency and a broad spectrum, and makes the liquor packaging cartons stored for a long time. Components of the mildew inhibitor are also selected from food additive components, so the mildew inhibitor has the advantages of food safety meeting, greenness, environmental protection, non-pollution and non-toxicity, and is suitable for mildew prevention of various liquor packaging cartons.

Description

technical field [0001] The invention belongs to the technical field of packaging, in particular to an antifungal agent for liquor packaging cartons and a preparation method thereof. Background technique [0002] Packaging box is the box used for packaging. According to the material, it is classified into paper box, iron box, wooden box, cloth box, leather box, acrylic box, corrugated box, PVC box, etc., which are widely used in daily life. [0003] Liquor packaging boxes are mostly cartons, and the production process is roughly as follows: first print on thin cardboard to make colored mounting paper, then paste the thick cardboard and mounting paper with glue, and finally put it indoors to dry. be usable. Cardboard is a thick paper sheet made of various pulps and interwoven fibers. The glue is white latex, which is obtained by emulsion polymerization with water as the dispersion medium, and is a water-based environmentally friendly glue. It is widely used in wood, furnitu...
