Abstract
The utility model discloses a card-protective membrane which takes a plastic film layer as a substrate, and an adhesion agent layer is uniformly distributed on the back surface of the substrate. The surface of the adhesion agent layer is in a ribbon pattern, compared with the existing plane adhesion agent layer, the material is saved. As the surface of the adhesion agent layer is in a new ribbon pattern, not a traditional plane pattern, the membrane is hard to harden when being slightly pressed in the conveying and storing process. Channels which can lead air bubbles from being discharged at the outer edge of the card-protective membrane are formed among the ribbons, and the air bubbles of the adhesion agent layer, generated in the hot film-laminating process, can be timely exhausted through the channels, and the obtained film-laminating card has no air bubbles, and the card is artistic and neat.
Description
Technical field
The utility model relates to a kind of card-protecting film, refers in particular to a kind of card-protecting film of card-protecting film adhesive layer surface alteration of form.
Background technology
Card-protecting film claims the plastic packaging film again, by plastic film as substrate; at substrate back coated tackiness agent, the senior flaky packaging material that forms through special processing treatment is widely used in identity card again; the historical accounts of past events, photo, picture; credit card, license licensed licenser licence, operation license; precious letters; security, the pass, the sealing up for safekeeping and protecting of all kinds of flaky materials such as representative certificate; flaky material by plastic packaging has waterproof; the anti-correction, protection against the tide, anti-damaging by worms; anti-going mouldy; remarkable function such as corrosion-resistant grade, not only attractive in appearance, and improved boldness.The card-protecting film of prior art, adhesive surface is smooth, waste material.Card-protecting film needs heat to cross and moulds processing in actual application, has the one side of tackiness agent to be close to protected card; the smooth card-protecting film of adhesive surface is crossed in the process of moulding in heat; the bubble that tackiness agent produces can not be discharged, and making to mould has bubble in the card, and card is not attractive in appearance.
The utility model content
At the defective of prior art, the technical problem that the utility model need solve provides a kind of economical with materials and at transportation, pressurized is difficult for hardening in the storage process card-protecting film.
The technical problem that the utility model need solve is achieved through the following technical solutions: a kind of card-protecting film is substrate with plastic film layer (PET), and at the uniform binder layer of backside of substrate (EVA), described adhesive layer surface is striated.
Further: can in time discharge in order to make binder layer cross the bubble that produces in the process of moulding, form the passage that bubble can be discharged the card-protecting film outer between the described striped in heat.
Further again: described plastic film layer is a polyester film layer, and described binder layer is a hot melt adhesive layer.
Compared with prior art, the adhesive layer surface of above-mentioned card-protecting film is striated, compares economical with materials with the binder layer of surfacing.Because adhesive layer surface is novel striped mode, is not traditional plane form, so slight pressurized is difficult for hardening in transportation, storage process.Form the passage that bubble can be discharged the card-protecting film outer between described striped, make binder layer cross the bubble that produces in the process of moulding in heat and in time discharge by this passage that the mistake of gained is moulded the no bubble of card, card is attractive in appearance smooth.
Description of drawings
Fig. 1 is the utility model structural representation;
Wherein 1 plastic film layer, 2 binder layers, 3 passages.
Specific embodiments
For the ease of those skilled in the art's understanding, describe in further detail below in conjunction with specific embodiment and 1 pair of the utility model structural principle of accompanying drawing:
A kind of card-protecting film is substrate with plastic film layer 1, and at the uniform binder layer 2 of backside of substrate, described binder layer 2 surfaces are striated.
Can in time discharge in order to make binder layer cross the bubble that produces in the process of moulding, form the passage 3 that bubble can be discharged the card-protecting film outer between the described striped in heat.
Described plastic film layer 1 is a polyester film layer.
Described binder layer 2 is hot melt adhesive layers.
Compared with prior art, binder layer 2 surfaces of above-mentioned card-protecting film are striated, compare economical with materials with the binder layer 2 of surfacing; And in transportation, storage process, be difficult for hardening behind the card-protecting film pressurized.Owing to form the passage 3 that bubble can be discharged the card-protecting film outer between the striped, binder layer is crossed the bubble that produces in the process of moulding in heat and is in time discharged by this passage 3.The mistake of gained is moulded does not have bubble in the card, card is attractive in appearance smooth.
The above is a preferred embodiment of the present utility model, and under the situation that does not break away from the present utility model design, any conspicuous distortion and the replacement carried out all belong within the utility model protection domain.
Claims (4)
1, a kind of card-protecting film is substrate with plastic film layer (1), at the uniform binder layer of backside of substrate (2), it is characterized in that: described binder layer (2) surface is striated.
2, card-protecting film according to claim 1 is characterized in that: form the passage (3) that bubble can be discharged the card-protecting film outer between the described striped.
3, card-protecting film according to claim 2 is characterized in that: described plastic film layer (1) is a polyester film layer.
4, card-protecting film according to claim 3 is characterized in that: described binder layer (2) is a hot melt adhesive layer.
