The card protecting film does not generate bubbles and creases when in use and has beautiful appearance.

Description

Grid gum card protecting film structure

Technical Field

The utility model relates to a card protecting film field especially relates to a net gum card protecting film structure.

Background

Most card protecting films on the market are flat thin films, and when the card protecting films are adhered to the surface of a plane material, air bubbles are easily generated, so that the appearance is greatly influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a net gum card protecting film structure is provided, the defect of prior art has been overcome, better application effect has.

The utility model discloses the technical problem that will solve realizes through following technical scheme:

the utility model provides a net gum card-protecting membrane structure, includes upper and lower two-layer composite film structure, and the upper film is the multilayer structure of laminating, and lower floor's film is the multilayer structure of laminating, and the one deck of bottom surface is for having the net impressed watermark from type paper layer among the lower floor's film multilayer structure, is removable pressure sensitive adhesive layer on the type paper layer, and removable pressure sensitive adhesive layer has the net line that corresponds with the net impressed watermark from type paper layer.

As right the utility model discloses a further improvement, lower floor's film has five layer structures, is the EVA layer for the first layer from inside to outside in proper order, and the second floor is the PE layer, and the third layer is the BOPET layer, and the fourth layer is for removing pressure sensitive adhesive layer, and the fifth layer is for having the release paper layer of net face structure.

As right the utility model discloses a further improvement, upper film has three layer construction, is the BOPET layer for the first layer from the extroversion in proper order, and the second floor is the PE layer, and the third layer is the EVA layer.

The utility model has the advantages that:

the adoption has the portable pressure sensitive adhesive layer of mesh face structure from type paper collocation, can be used to paste on various plane materiel, it has the grid line and still leaves the gap and make the air can hold the circulation when pasting the plane materiel, the bubble can be discharged smoothly, it leaves from type paper layer to tear after moulding, can paste whole material in various surface fabric surfaces and be difficult for dropping, and also can tear after pasting, paste on other objects again, can repeat many times paste, application range and reuse rate have greatly been extended.

Fig. 2 is a partial schematic view of the construction of the grid backed adhesive card guard membrane of fig. 1.

Detailed Description

The present invention will be further described with reference to the following description and embodiments.

As shown in fig. 1, a grid back adhesive card-protecting film structure has an upper and a lower composite film structures, the upper film 1 is a laminated three-layer structure, wherein the first layer is a BOPET (biaxially oriented polyester film) layer 11, the second layer is a PE (polyethylene) layer 12, and the third layer is an EVA (ethylene-vinyl acetate copolymer) layer 13; the lower film 2 is a five-layer structure, wherein the first layer is an EVA layer 21, the second layer is a PE layer 22, the third layer is a BOPET layer 23, the fourth layer is a removable pressure sensitive adhesive layer (commercially available conventional product) 24, the fifth layer is the release paper layer (commercially available conventional product) 25 with grid embossing, and the removable pressure sensitive adhesive layer 24 has grid lines corresponding to the grid embossing of the release paper layer 25, as shown in fig. 2.

Paper is put between the upper film 1 and the lower film 2, after hot pressing and plastic coating, the release paper layer 25 is uncovered, the movable pressure-sensitive adhesive layer 24 is used for pasting on various plane materiel, and pasting can be repeated for many times, thus greatly expanding the application range and the reutilization rate. Meanwhile, because the pressure sensitive adhesive layer 24 can be moved has the grid lines, according to the common knowledge, when the conventional plane film is pasted on the surface of the plane material, the plane film is excessively combined with the surface of the plane material too tightly, the air bubbles entering the inner surface are not easy to discharge, the air bubble stock causes the protrusion to influence the leveling, and the pressure sensitive adhesive layer 24 which can be moved has the grid lines, so that the air can be contained and circulated when the plane material is pasted tightly, and the air bubbles can be discharged smoothly.

The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, all should regard as belonging to the utility model discloses a protection scope.
