Abstract
The invention discloses a back adhesive film structure with good surface protection performance, high image-text color effect and definition in presswork, no bubbles in use and good convenience and controllability and a preparation method of a back adhesive film. The back adhesive film is divided into seven layers from the front to the back, namely a first transparent polyester film layer, a first ethylene vinyl acetate (EVA) hot melt adhesive layer, a piece of printing paper, a second EVA hot melt adhesive layer, a second transparent polyester film layer, an adhesive layer and a piece of silicon coated protective paper in sequence. The preparation method of the back adhesive film comprises the following steps of: coating EVA hot melt adhesive on the surface of a transparent polyester film by an extrusion casting process to form a pre-coating film; coating adhesive on the polyester surface of the pre-coating film by a dry complex process, and pressing the dried pre-coating film and the silicon coated protective paper under back pressure to form a back adhesive pre-coating film; and folding and coiling the EVA hot melt adhesive surfaces of the pre-coating film and the back adhesive pre-coating film up and down, and finally forming the back adhesive film by cutting, edge ironing and chamfering.
Description
?
Technical field
The present invention relates to a kind of back-adhesive film, paste, pack pad pastings such as pad pasting, pressure sensitive adhesive, the subsides of following one's inclinations like the caution advertisement, specifically is structure of a kind of back-adhesive film and preparation method thereof.
Background technology
Advertisement has been penetrated into the every aspect of life as a kind of mass media mode; Wherein, Various forms of outdoor advertisings have appeared at each corner of public situation, and as a kind of important form of outdoor advertising, the plane pad pasting is a kind of more common advertisement form.Meanwhile, living environment always is accompanied by the unknown or accident, can bring puzzled even dangerous to the mankind.In order to prevent that such adverse events from taking place, also need put up some prompting picture and text in strange or proemial occasion and warn or instruct some human behaviors.In addition, pad pastings such as packing pad pasting, pressure sensitive adhesive, the subsides of following one's inclinations also are the staples in the daily life.
The product of putting up that prior art is used to point out has adhesive sticker, plane nameplate and conventional labels etc., wherein:
1. adhesive sticker: a kind of is lining with paper or film, and the back side scribbles adhesive, to be coated with a kind of composite that the silicon protection sheet is a base stock.Shortcoming be after the lining printing as not covered with protective film be easy to fade, superficial injury such as scratch; But can reduce the color saturation of printing figure message behind the interpolation diaphragm, it is dull that picture and text show slightly.The film adhesive sticker is soft partially, and the glue face is prone to have residual causing of air to have aeration attractive in appearance when smooth during use.
2. plane nameplate: mainly be to manufacture with aluminum alloy materials, the color on its face is not a paint, but through after the anodic oxidation, the color of catching, different according to process, can be monochromatic, also can be 2-3 kind color.Shortcoming is phenomenons such as fading appears in time one long card face easily, general trace, compares on the high side than film.
3. conventional labels: directly print with paper or film, need assist brush coating during use.Shortcoming: it is long, not too convenient and swift that use has pollution, decals time.
Summary of the invention
It is good that technical problem to be solved by this invention provides a kind of surfacecti proteon performance; The picture and text color effect of middle printed matter and readability are high; During use bubble can not appear, and convenience with can handling good back-adhesive film structure, the preparation method of this back-adhesive film is provided in addition.
The structure of back-adhesive film of the present invention, being divided into to the back side from the front of back-adhesive film is seven layers, is followed successively by the first transparent polyester film layer; The one EVA hot melt adhesive layer; Printing paper, the 2nd EVA hot melt adhesive layer, the second transparent polyester film layer, adhesive layer and be coated with the silicon protection sheet.
The above-mentioned first transparent polyester film layer and the second transparent polyester film layer thickness are 25 ~ 100 microns.
An above-mentioned EVA hot melt adhesive layer and the 2nd EVA hot melt adhesive layer thickness are 20 ~ 50 microns.
Above-mentioned adhesive layer thickness is 12 ~ 25 microns.The grammes per square metre that is coated with the silicon protection sheet is 80 ~ 130g.
The present invention also provides the preparation method of this back-adhesive film, and it may further comprise the steps:
1) plane materiel adopts transparent polyester film, forms pre-coating film through extruding casting technique at transparent polyester film surface-coated EVA PUR.
2) with pre-coating film through the dry type combination process at the polyester face coating binder of pre-coating film, dry back be coated with silicon protection sheet back pressure and form the gum pre-coating film.
3) with pre-coating film and the step 2 of step 1) preparation) the EVA PUR face involutory rewinding up and down of the gum pre-coating film of preparation, at last through cutting, scald limit, chamfering formation back-adhesive film.
4) back-adhesive film with step 3) preparation keeps flat, and starts an end that does not scald the limit and puts into printing paper, be heated to 110 ℃ ~ 130 ℃ of plastic packaging machine, puts into plastic packaging machine to back-adhesive film and crosses and moulding typing and get product.
The present invention and prior art relatively have the following advantages:
1. from overall structure and adhesive sticker relatively, back-adhesive film is done protection by the two layers polyester film, does not rise softly, can one in the process of fitting produce bubble, and protective layer can waterproof, superficial injuries such as anti-scratch and anti-correction.
2. compare from operability and conventional labels, back-adhesive film need not assisted brush coating, and is easy to use with using with subsides, saves time environmentally safe.
3. from using controlled and adhesive sticker, nameplate relatively, prior art has higher requirement to typography and printing equipment, the also industrialized production in enormous quantities of needs of one type of independent printed matter, and client's selection has limitation.The printed matter that back-adhesive film is used can be by autonomous intention of client and design; Only need common printer prints; Can be with seal with envelope; Be a product that can independently control type by the client, after the product heat-sealing, can also play anti-reflection effect, improved the attractive in appearance and readability of printing figure message greatly printed matter.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1, the structure of back-adhesive film of the present invention, from the front to the back side, being divided into is seven layers; Be followed successively by the first transparent polyester film layer, 1, the one EVA hot melt adhesive layer 2, printing paper 3, the 2nd EVA hot melt adhesive layer 4; The second transparent polyester film layer 5, adhesive layer 6 and be coated with silicon protection sheet 7.Wherein the first transparent polyester film layer 1 and the second transparent polyester film layer, 5 thickness are 25 ~ 100 microns, as the protective layer of product.The one EVA hot melt adhesive layer 2 and the 2nd EVA hot melt adhesive layer 4 thickness are 20 ~ 50 microns, and this two-layer upside scalds the limit is bonded together pre-coating film, during use are placed on printing paper 3 centre of two-layer EVA hot melt adhesive layer.Adhesive layer 6 thickness are 12 ~ 25 microns, and put up on the plane that is used for product.The grammes per square metre that is coated with silicon protection sheet 7 is 80 ~ 130g, is used to protect adhesive.
