Environmentally-friendly anti-sticking agent for food package

Abstract

The invention relates to an environmentally-friendly anti-sticking agent for a food package. The raw material formula of the environmentally-friendly anti-sticking agent mainly comprises a solvent part, a resin part and an accessory ingredient part, wherein the solvent part comprises 20-30% of absolute ethyl alcohol, 10-15% of acetic ether and 9-13% of cyclohexane; the resin part comprises 10-20% of nitrocotton resin, 10-20% of acrylic resin and 1-5% of polyamide resin; the accessory ingredient part comprises 8-12% of pentaerythritol ester, 1-5% of wax, 0.8-1.2% of citric acid and 3-7% of water. Because the anti-sticking agent of the technical scheme is almost nontoxic because the specific solvent part formula and the specific resin part formula are adopted. Most importantly, the anti-sticking agent has excellent solvent release force, and almost no solvent remains on the surface of a wrappage and the like, so that the environmentally-friendly anti-sticking agent can satisfy the requirement of food health security. Meanwhile, the anti-sticking agent of the technical scheme also has the excellent anti-sticking property of the existing anti-sticking agent, and has no influence to the stickiness of the reverse side glue.

Description

technical field [0001] The invention relates to an anti-adhesive agent, in particular to an anti-adhesive agent used in food packaging. Background technique [0002] Although adhesives are currently widely used in packaging, office supplies, labels, trademarks, etc., in the current packaging processes that require high hygiene and safety requirements such as food and medicine, printing on the side that requires adhesion (painting) Cloth) After the required adhesive layer, it is necessary to print anti-sticking materials on the reverse side to prevent the printed packaging materials from sticking together when they are rolled, which will affect the later cutting and packaging. [0003] On the one hand, the anti-adhesive coating should have good anti-adhesion, but it should not affect the viscosity of its reverse adhesive. On the other hand, this anti-adhesive coating is likely to be in direct or indirect contact with food, so it must have Good solvent release. [0004] Howe...

Problems solved by technology

[0004] However, most of the anti-adhesive coatings in the prior art can only use some toxic solvents to ensure anti-adhesion, but their volatile substances will remain on the surface of the packaging, which may affect food, thereby affecting people's health

However, if an environmentally friendly non-toxic solvent is used, it is difficult to achieve a good anti-sticking effect, which brings great difficulties to packaging production.

[0005] The packaging of most products currently on the market is difficult to meet the hygienic and safety requirements for direct or indirect contact with food
