Abstract
The invention discloses single-surface PEK (Polyether Ketone) coated release paper which comprises bottom-layer paper and a coated layer, wherein the coated layer is directly arranged on the single surface of the bottom-layer paper in parallel; the bottom-layer paper is made of all-wood paper; the coated layer is formed by the injection molding of polyethylene; and the external surface of the coated layer is a rough surface on which a plurality of small holes are formed evenly. Therefore, the surface roughness of the coated layer is enhanced, i.e., the coated layer can be firmly bonded with an adhesive tape; and the coating of a silicone oil layer is not required, so that the transferring of the silicone oil layer is avoided, i.e., the coated layer is easy to bond and peel off. Consequently, the phenomenon that the coated layer cannot be peeled off well is avoided; and the flatness and the toughness of the release paper are improved. As a result, the release paper is difficult to deform and the service life of the release paper is prolonged.
Description
Technical field
The present invention relates to the protective film of electronic product field, particularly relate to a kind of single face PEK film release liners.
Background technology
Release liners claims again silicone oil paper, separate paper.Mainly play the effect of the sticking object in isolation strip, its scope of application is most of is in the same place with tool is sticking, such as adhesive tape, so, generally to use the product of adhesive tape and all can use release liners.Generally need to be stripped from use, abandon; That uses now is wider, is in fields such as electronics, advertising and printings, is mainly adhesive tape or with the carrier of glue goods.
Existing film release liners has three-layer structure usually, ground paper layer, leaching membrane layer and silicon layer, be body paper after film, on the film face coating silicone oil production and.The silicon layer of this class release liners very easily shifts, and can cause peeling off of release liners bad, makes the adhesive tape of attaching or dirty with the carrier surface of glue goods, and poor flatness, and is yielding, thereby affects its service life and result of use.
Summary of the invention
The technical problem that the present invention mainly solves is: for the deficiencies in the prior art, provide a kind of single face PEK film release liners, be easy to fit and peel off, guarantee not have peel off bad, and increased flatness and the toughness of release liners, made it not yielding, increase service life.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of single face PEK film release liners is provided, comprise: ground paper layer and leaching membrane layer, the single face of described ground paper layer is directly parallel is covered with described leaching membrane layer, described ground paper layer is the whole wood pulp ply of paper, described leaching membrane layer is polyethylene injection moulding rete, and the outer surface of described leaching membrane layer is matsurface, evenly offers some apertures on it.
In a preferred embodiment of the present invention, the thickness of described ground paper layer is 0.075-0.15mm.
In a preferred embodiment of the present invention, the thickness of described leaching membrane layer is 0.015-0.03mm.
In a preferred embodiment of the present invention, described aperture be shaped as circle, ellipse, triangle, square, rectangle, rhombus or polygon.
In a preferred embodiment of the present invention, the degree of depth of described aperture is 2-5 μ m.
The invention has the beneficial effects as follows: by cover one deck leaching membrane layer on ground paper layer, and the outer surface of leaching membrane layer is designed to matsurface, offer in the above some apertures, in order to increase the roughness on leaching membrane layer surface, make the bonding tightr of itself and adhesive tape, and need not the silicon-coating oil reservoir, avoided the transfer of silicon layer, be easy to fit and peel off, guarantee not have peel off bad, and increased flatness and the toughness of release liners, made it not yielding, increase service life.
Description of drawings
Fig. 1 is the structural representation of single face PEK film release liners of the present invention one preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, ground paper layer, 2, leaching membrane layer.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made more explicit defining.
See also shown in Figure 1ly, the embodiment of the present invention comprises:
A kind of single face PEK film release liners, do not contain silicon layer, comprise: ground paper layer 1 and leaching membrane layer 2, the single face of described ground paper layer 1 is directly parallel is covered with described leaching membrane layer 2, described ground paper layer 1 is the whole wood pulp ply of paper, described leaching membrane layer 2 is polyethylene injection moulding rete, and the outer surface of described leaching membrane layer 2 is matsurface, evenly offers some aperture (not shown) on it.
Wherein, the thickness of described ground paper layer 1 is 0.075-0.15mm.
The thickness of described leaching membrane layer 2 is 0.015-0.03mm.
Described aperture be shaped as circle, ellipse, triangle, square, rectangle, rhombus or polygon.
The degree of depth of described aperture is 2-5 μ m.
Single face PEK film release liners of the present invention is applicable to the fields such as electronics, advertising and printing, is used for fitting with adhesive tape or with the carrier of glue goods.
The present invention has disclosed a kind of single face PEK film release liners, by covering one deck leaching membrane layer on ground paper layer, and the outer surface of leaching membrane layer is designed to matsurface, offer in the above some apertures, in order to increase the roughness on leaching membrane layer surface, make the bonding tightr of itself and adhesive tape, and need not the silicon-coating oil reservoir, avoided the transfer of silicon layer, be easy to fit and peel off, guarantee not have and peel off badly, and increased flatness and the toughness of release liners, make it not yielding, increase service life.
The above is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
