Abstract

The invention discloses a release film with anti-counterfeiting marks. The release film is characterized by comprising a base film layer, a middle layer and a release layer, the middle layer is an anti-counterfeiting mark layer, the release layer is formed by coating a release agent, and the release agent is prepared from, by mass, 2-5 parts of polyethylene wax particles, 18-35 parts of vinyl silicone resin, 12-25 parts of melamine resin, 3-7 parts of nanometer titania, 2-4 parts of sodium polyacrylate, 1-3 parts of coupling agent, 1.5-3 parts of flatting agent and 12-28 parts of solvent. All the components of the release film are matched with one another, so the release layer can be evenly coated on the base film layer, the middle layer is the anti-counterfeiting mark layer and has an anti-counterfeiting effect, and counterfeiting of illegal merchants is avoided; polyethylene wax particles are contained, so the release film shows light and stable release force and has good scratch-resistant performance.

Description

technical field [0001] The invention relates to a release film, in particular to a release film with anti-counterfeiting marks. Background technique [0002] Release film, also known as anti-adhesive film, is based on polyethylene terephthalate plastic (PET for short), biaxially oriented polypropylene film plastic (BOPP for short), polyethylene plastic (PE for short), and carbonate plastic (PET for short). PC), polystyrene plastic (referred to as PS), polypropylene plastic (abbreviated as CPP) is a material with low surface energy on the surface. When the adjacent adhesive is peeled from the release surface, the release material can be easily peeled off or removed without damaging the physical properties of the adhesive. The release film is characterized by smooth surface, high cleanliness, stable size in subsequent processing, adjustable transparency and color, and a wide range of options for film thickness and substrate types. Utilizing these characteristics of the relea...
