Abstract

The utility model discloses a kind of biaxial stretching BOPP protection film, comprise polypropylene based layers, described polypropylene based layers is formed by two-way stretch; Described polypropylene based layers side is coated with the bond layer of not cull, and described bond layer is arranged by some adhesive strip parallel interval and formed, or is evenly arranged by point-like glue grume and form; Described polypropylene based layers opposite side compound one deck corona layer.The utility model selects polypropylene based layers through two-way stretch as base material; convenient operation and automatic milling are cut; greatly reduce tooling cost; adopt two to three-layer polypropylene basic unit to be that its thickness is moderate simultaneously; solve protective membrane and cross the soft or too high problem of deflection; the utility model protective membrane can not produce electrostatic phenomenon simultaneously, and can reuse.

Description

Biaxial stretching BOPP protection film
Technical field
The utility model relates to a kind of BOPP film, is specifically related to a kind of biaxial stretching BOPP protection film.
Background technology
BOPP film is a kind of very important flexible packing material, and BOPP film is colourless, odorless, tasteless, nontoxic, and has high tensile, shock strength, rigidity, obdurability and the good transparency.BOPP film surface can be low, needs to carry out corona treatment before gluing or printing.After corona treatment, BOPP film has good printing adaptability, can chromaticity printing and obtain exquisite appearance effect, is thus commonly used for the surface material of laminated film.The materials such as glass, sheet metal, plastic plate are being copied mechanically in process and in use procedure, and its surface is easily subject to contact stain(ing) or polishing scratch scratches.But protective membrane is not easy operation time too thin, thick later meeting is because the deflection of PET is very high, so when being pasted onto the material surface such as glass, sheet metal, plastic plate of radian, easily tilt.
Utility model content
The utility model overcomes the deficiencies in the prior art, provides a kind of biaxial stretching BOPP protection film, solves protective membrane too softness and the too high problem of protective membrane deflection in prior art, solves the electrostatic problem of existing protective membrane simultaneously.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
A kind of biaxial stretching BOPP protection film, comprise polypropylene based layers, described polypropylene based layers is formed by two-way stretch; Described polypropylene based layers side is coated with the bond layer of not cull, and described bond layer is arranged by some adhesive strip parallel interval and formed, or is evenly arranged by point-like glue grume and form; Described polypropylene based layers opposite side compound one deck corona layer.
Further technical scheme bond layer is coated with one deck pressure-sensitive adhesive layer.
Further technical scheme is compound one deck release film layer on corona layer.
Further technical scheme is polypropylene based layers is 2 to 3-tier architecture.
The further technical scheme one that to be point-like glue grume be in trilateral point-like glue grume, oval point-like adhesive block, circular point-like glue grume, rhombus point-like adhesive block.
Further technical scheme is adhesive strip is curve adhesive strip.
Compared with prior art; the beneficial effects of the utility model are: the utility model selects polypropylene based layers through two-way stretch as base material; convenient operation and automatic milling are cut; greatly reduce tooling cost; adopt two to three-layer polypropylene basic unit to be that its thickness is moderate simultaneously; solve protective membrane and cross the soft or too high problem of deflection, the utility model protective membrane can not produce electrostatic phenomenon simultaneously, and can reuse.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figure 1, the utility model embodiment biaxial stretching BOPP protection film, comprise polypropylene based layers 3, described polypropylene based layers is formed by two-way stretch; Preferably, polypropylene based layers is 2 to 3-tier architecture, ensures that it was unlikely to thin or blocked up.Described polypropylene based layers side is coated with the bond layer 4 of not cull, preferably, bond layer described in the present embodiment is arranged by some curve adhesive strip parallel interval and is formed, or is evenly arranged by point-like glue grume and form, make it have portability, can reuse; Point-like glue grume can be in trilateral point-like glue grume, oval point-like adhesive block, circular point-like glue grume, rhombus point-like adhesive block.
In the present embodiment, polypropylene based layers opposite side compound one deck corona layer 2, can prevent electrostatic.As preferred embodiment, according to another embodiment of the present utility model, the present embodiment, on the basis of above-described embodiment, bond layer is coated with one deck pressure-sensitive adhesive layer 5, and it has high bonding, the feature such as high temperature resistant, can widespread use in protective membrane.
Further, preferably, on corona layer, compound one deck release film layer paper 1, also can cover one deck release film layer.
Spoken of in this manual " embodiment ", " another embodiment ", " embodiment ", etc., refer to the specific features, structure or the feature that describe in conjunction with this embodiment and be included at least one embodiment of the application's generality description.Multiple place occurs that statement of the same race is not necessarily refer to same embodiment in the description.Furthermore, when describing specific features, structure or a feature in conjunction with any one embodiment, what advocate is also drop in scope of the present utility model to realize this feature, structure or feature in conjunction with other embodiments.
Although the multiple explanatory embodiment here with reference to utility model is described the utility model, but, should be appreciated that, those skilled in the art can design a lot of other amendment and embodiment, these amendments and embodiment will drop within spirit disclosed in the present application and spirit.More particularly, in the scope of, accompanying drawing open in the application and claim, multiple modification and improvement can be carried out to the building block of subject combination layout and/or layout.Except the modification of carrying out building block and/or layout is with except improvement, to those skilled in the art, other purposes also will be obvious.
