Description

Aluminum-based anti-counterfeiting release film

Technical Field

The utility model relates to a from type membrane technical field, especially relate to an aluminium base is prevented falsification from type membrane.

Background

In order to reduce the possibility that valuables are exchanged in the transportation process or are privately unpacked without authorization, the security of the sealing box is ensured, and the anti-counterfeiting sealing adhesive tape is more and more favored by users. Traditional anti-fake joint sealing sticky tape is with general joint sealing sticky tape difference be with anti-fake type matrix information preset on anti-fake joint sealing sticky tape, and anti-fake type matrix information will stay on the joint sealing surface when anti-fake joint sealing sticky tape tears from the carton surface, and does not have any adhesive on label face after tearing and the face of bearing, plays anti-fake effect to show the joint sealing has the vestige of being opened, plays and stays trace and warning effect. The anti-counterfeiting sealing tape is undoubtedly a safety lock for sealing in the process of transportation, so that unscrupulous persons with malicious attempts can abandon the malicious attempts; however, the conventional anti-counterfeiting sealing adhesive tape has small peeling force, so that a substrate with large peeling force cannot be used, or the part which does not need to be transferred can be transferred to the sealing box. Therefore, there is an urgent need for improvement of the conventional anti-counterfeit sealing tape.

Disclosure of Invention

The utility model discloses it is little to the traditional anti-fake joint sealing sticky tape peel force that exists among the prior art, can not use the substrate of big peel force, otherwise can not need the partial of transferring also can be transferred to the joint sealing on, the not enough technical problem of degree of coverage of sticky tape provides a new aluminium base anti-fake from the type membrane simultaneously.

The mixed resin layer with the solid content of 10-20%, the viscosity of 12-25 seconds and the glass transition temperature of 70-100 ℃ is used as the anti-counterfeiting layer, so that the anti-counterfeiting effect of the anti-counterfeiting layer is better. The mixed resin layer is prepared by compounding 40-60 parts by weight of acrylic resin, 10-15 parts by weight of polyurethane resin and 20-25 parts by weight of polyester resin.

Preferably, the aluminum-based anti-counterfeiting release film comprises a metal protective layer and a protective resin layer, wherein the metal protective layer is a protective resin layer with the solid content of 28-32%, the viscosity of 120-200 seconds and the glass transition temperature of 70-100 ℃.

The metal protection layer adopts solid content to be 28% ~ 32%, viscosity is 120 ~ 200 seconds, glass transition temperature is 70 ~ 100 ℃'s protection resin layer, isolated metal level that can be better and external air, moisture contact to prevent that the metal level from being oxidized, corroding, and then ensure and suitably prolong the utility model discloses a life. The protective resin layer is formed by mixing and stirring 50-60 parts by weight of polyester modified acrylic resin, 15-20 parts by weight of vinyl chloride-vinyl acetate-vinyl alcohol copolymer resin, 18-24 parts by weight of methylamino resin, 0.1-0.12 part by weight of tin catalyst, 30-35 parts by weight of ethyl acetate and 15-17 parts by weight of butyl acetate solution.

Preferably, the aluminum-based anti-counterfeiting release film is provided with a pattern on the anti-counterfeiting layer.

The pattern that sets up on the anti-fake layer makes more diversified, the nature directly perceived of visual effect that aluminium base anti-fake from the anti-fake performance of type membrane embodies, even get the utility model discloses an anti-fake effect is better.

Preferably, the thickness of the metal layer of the aluminum-based anti-counterfeiting release film is 80-120 nm.

Adopt the metal level of 80 ~ 120nm thickness, the utility model discloses a better of side cut performance and luminousness, and can reduce the utility model discloses a cost.
