The radium-shine sealing tape of invisible graph
Technical field
The utility model relates to a kind of radium-shine sealing tape, especially relates to a kind of radium-shine sealing tape that can invisible graph.
Background technology
Present radium-shine sealing tape be mainly used in spray paint, industries such as decoration, joint sealing, packing are fixed, building decoration fixing, also be used for office, study etc.This sealing tape mainly uses OPP to be starting material, coating one deck polymeric coating layer on OPP, at high score subgraph lamination seal laser holographic picture and text, be coated with water-borne pressure sensitive adhesive on polymeric coating layer, oven dry is made, and the viscosity of this adhesive tape is big, be not easy to come off after fixing, have heatproof, anti-solvent, the characteristic such as glue of overflowing, but this adhesive tape has only a kind of antiforge function of laser graphic, is easy to be copied.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of radium-shine sealing tape that invisible graph is arranged.
The technical scheme in the invention for solving the technical problem is: the radium-shine sealing tape of a kind of invisible graph, with PET is starting material, the PET not one side of corona film is provided with separating layer, on separating layer, be provided with information layer, on information layer, be provided with aluminium coated, on aluminium coated, be provided with embossed plies, on embossed plies, be provided with the resistant to elevated temperatures pressure sensitive adhesive of acid-fast alkali-proof.
In order to make the adhesive tape can be water-fast and high temperature resistant, described PET not the another side of corona film be provided with silicon layer.
Adopt the adhesive tape of said structure, not only have this a kind of anti-fake mark of laser graphic, more than a kind of anti-fake mark of invisible graph, more gorgeous on appearance effect, difficulty more aspect forgery.

1, not corona film 3, separating layer 4, information layer 5, aluminium coated 6, embossed plies 7, the resistant to elevated temperatures pressure sensitive adhesive of acid-fast alkali-proof of silicon layer 2, PET
Embodiment
Fig. 1 is the structural representation of the radium-shine sealing tape of invisible graph, the radium-shine sealing tape of a kind of invisible graph, with PET is starting material, the PET not one side of corona film 2 is provided with separating layer 3, on separating layer 3, be provided with information layer 4, on information layer 4, be provided with aluminium coated 5, on aluminium coated 5, be provided with embossed plies 6, on embossed plies 6, be provided with the resistant to elevated temperatures pressure sensitive adhesive 7 of acid-fast alkali-proof.PET not the another side of corona film 2 be provided with silicon layer 1.
Fig. 2 is the production scheme of the radium-shine sealing tape of invisible graph, earlier be not coated with the silicone oil that is covered with version on the one side of corona film 2 at PET, waterproof heat-resisting, at the PET another side print separation layer 3 of corona film 2 not, printing information layer 4 on the face of separating layer 3, vacuum aluminum-coated afterwards, to its mold pressing, go up glue at last then.
The radium-shine sealing tape of invisible graph has been added a kind of anti-counterfeiting technology, and is more gorgeous on appearance effect, mainly overcome the printing issues of separating layer.
