Abstract
The utility model discloses a card protecting film which is sequentially provided with an EVA (Ethylene-Vinyl Acetate) layer, a PET (polyether amine) matrix layer and an anti-static layer which are tightly adhered together from bottom to top, wherein a raised anti-skid pattern is arranged on the PET matrix layer and is of a ring or strip-shaped structure, and the thickness of the card protecting film is 0.08mm. After the anti-static layer is sprayed and coated on the upper surface of the PET matrix body, the anti-static capacity is durable, the transparency and other performances of the card protecting film are not influenced; the card protecting film is easily separated without being adhered together due to the design of the raised anti-skid pattern, and is taken more easily, and hardly slides off; the thickness of the card protecting film can be reduced to 0.08mm; and the card protecting film makes up the blank of the market.
Description
Technical field
The utility model relates to a kind of card-protecting film, is specifically related to a kind of anti-electrostatic, anti-skidding card-protecting film.
Background technology
Card-protecting film, claimed again film, English name laminating film.By mylar as substrate, the even coated tackiness agent of monolithic, the more senior flaky packaging material forming through special processing treatment; be widely used in identity card, the historical accounts of past events, photo; sealing up for safekeeping and protecting of all kinds of flaky materials such as picture, is had waterproof by the flaky material of plastic packaging, anti-correction; protection against the tide, Anti-moth-eating, anti-going mouldy; the remarkable functions such as resistance to general soda acid pond agent corrosion; and well-pressed attractive in appearance, transparency is high, be therefore widely used.
The main material of card-protecting film is PET and EVA, and surface resistivity volume resistance is greater than 10
12, therefore there are good insulating property.And just due to this reason, it is very easily producing static because plastics producing carrying contact, separated, friction, collision, get involved electromagnetic induction occasion be all and may, or even avoid till the ass ascends the ladder these occasions, thereby brought the factor of static.The static charge accumulating all can be brought adverse influence to the processing of plastics and use, as causes the problems such as adsorbing powder dust, electric shock, electric discharge and burning.
In sum, need to increase the anti-static ability of card-protecting film.In the raw material PET having attempted at first at manufacture card-protecting film and EVA, add anti-electrostatic material, the card-protecting film of still making is in later stage use procedure, and anti-static ability wearing and tearing are too fast, so need to explore novel anti-static method, make it durable.
Meanwhile, existing card-protecting film is blocked up, and its surface is very smooth, there is no antiskid function, in use can make troubles, and therefore, also needs the non-skid property of card-protecting film to carry out some improvement.Make card-protecting film thickness reduction after improving to 0.08mm, and in the non-slip patterns of a kind of projection of its surface design, make slim card-protecting film also easy to use, can not be bonded together.
Utility model content
For solving the problems of the technologies described above, we propose a kind of card-protecting film, by the method for protruding non-slip patterns and spraying antistatic backing is set at PET body upper surface, solve the object that there is no antiskid function and electrostatic-proof function in prior art.
For achieving the above object, the technical solution of the utility model is as follows:
A card-protecting film, is disposed with the EVA layer, PET base layer and the antistatic backing that hold tightly together from top to bottom, on described PET base layer, is also provided with protruding non-slip patterns.
Preferably, described non-slip patterns is annulus or strip structure.
Preferably, the thickness of described card-protecting film is 0.08mm.
Compared with prior art, the utlity model has following advantage:
The utility model is after PET body upper surface spraying antistatic backing, and anti-static ability is lasting, and does not affect transparency and other performance of card-protecting film; The design of the non-slip patterns of projection can not be bonded together the easy separation of card-protecting film, takes card-protecting film and makes to be more prone to, and is also difficult for landing; Card-protecting film thickness can be reduced to 0.08mm; Enforcement of the present utility model can make up the blank in market.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only an embodiment of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to this accompanying drawing other accompanying drawing.
Fig. 1 is the disclosed a kind of card-protecting film cross-sectional view of the utility model embodiment;
Fig. 2 is the disclosed a kind of card-protecting film vertical view of the utility model embodiment.
The represented corresponding component title of numeral in figure:
1.EVA layer 2.PET base layer 3. antistatic backing 4. non-slip patterns
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only embodiment of the utility model, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Below in conjunction with embodiment and embodiment, the utility model is described in further detail.
Embodiment.
As shown in Figure 1 and Figure 2, a kind of card-protecting film, is disposed with the EVA layer 1, PET base layer 2 and the antistatic backing 3 that hold tightly together from top to bottom, on described PET base layer 2, is also provided with protruding non-slip patterns 4.
Described EVA layer 2 is to utilize the showering of film machine to form at the lower surface of PET base layer 1, and described antistatic backing 3 use spraying methods are painted on the upper surface of PET base layer 2.The anti-electrostatic card-protecting film that this method preparation forms, has lasting anti-static ability, can As time goes on not produce the phenomenon of deterioration.
Meanwhile, the non-slip patterns 4 of utilizing hot pressing complex method to be arranged on card-protecting film PET base layer 2 projections plays anti-skidding effect.In this example, non-slip patterns is toroidal, and non-slip patterns can also be strip structure certainly, can play too skidproof effect (not shown in FIG.).
The card-protecting film thickness that utilizes aforesaid method to form is 0.08mm; Secondly, the thickness of card-protecting film can also be other the arbitrary numerical value between 0.06-0.25mm.
Compared with prior art, the utlity model has following advantage:
The utility model is after PET body upper surface spraying antistatic backing, and anti-static ability is lasting, and does not affect transparency and other performance of card-protecting film; The design of the non-slip patterns of projection can not be bonded together the easy separation of card-protecting film, takes card-protecting film and makes to be more prone to, and is also difficult for landing; Card-protecting film thickness can be reduced to 0.08mm; Enforcement of the present utility model can make up the blank in market.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
