Abstract
The present invention discloses a kind of Novel release film, it is characterized by: the release film includes middle layer (1), the middle layer uses white PET film or pearly-lustre BOPP film, pass through adhesive phase (2) respectively in the upper and lower surface of middle layer (1) to be bonded with outer layer (3), the adhesive phase (2) is two-component polyurethane adhesive storehouse, and the outer layer (3) is pearly-lustre BOPP film.
Description
Technical field
The present invention relates to the production field of plastic film, especially a kind of Novel release film.
Background technique
In drug, cosmetic product, need largely to use release film, which are mainly applied to such as plaster, facial mask etc., these
Product is all fitted on release film, and when use directly removes product from release film.Present release film used on the market
Mainly by graining film and two kinds of light film, and both release films belong to single thin film, the poor problem of generally existing stiffness.Have
When be applied to heavy viscous material when be also easy to the case where being stripped layering occur.In view of the above-mentioned problems, demand one currently on the market
The release film planting high-stiffness, not removing.
Summary of the invention
The present invention is to propose a kind of high, not curled, anti-chemistry of stiffness to solve above-mentioned deficiency present in the prior art
The good Novel release film of moral character energy.
The technical solution of the invention is as follows: a kind of Novel release film, it is characterised in that: the release film includes centre
Layer 1, the middle layer use white PET film or pearly-lustre BOPP film, pass through adhesive respectively in the upper and lower surface of middle layer 1
Layer 2 is bonded with outer layer 3, and the adhesive phase 2 is two-component polyurethane adhesive storehouse, and the outer layer 3 is that pearly-lustre BOPP is thin
Film.
The present invention compared with the existing technology, has the advantages that
The Novel release film of this kind of structure type, using special symmetrical multilayered structure, therefore flatness when in use
It is higher, it will not there is a situation where crimp；While wherein interbed uses the white PET film or pearly-lustre BOPP film of high-stiffness, therefore
Very beautiful after composite molding, the class of integral product can get a promotion；And outermost layer is then BOPP film layer, the film layer
Polarity it is low, can be easily separated with content (plaster, facial mask, eye sticker etc.), and do not have liquor residue after isolation；In middle layer
Two-component polyurethane adhesive is used to carry out between outer layer be bonded, safety is good, and chemical resistance performance is more excellent.To sum up institute
It states, it may be said that this release film has a variety of advantages, and particularly suitable for promoting and applying in the art, market prospects are very
It is wide.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the embodiment of the present invention.
Specific embodiment
Below in conjunction with Detailed description of the invention a specific embodiment of the invention.A kind of Novel release film as shown in Figure 1:, should be from
Type film includes middle layer 1, and the middle layer uses white PET film or pearly-lustre BOPP film, in the upper and lower surface point of middle layer 1
Not Tong Guo adhesive phase 2 be bonded with outer layer 3, the adhesive phase 2 be two-component polyurethane adhesive storehouse, the outer layer 3
For pearly-lustre BOPP film.
Novel release film described in the embodiment of the present invention, due to using special symmetrical multilayered structure,
Flatness is higher when use, will not there is a situation where crimp；While wherein interbed uses the white PET film or pearly-lustre of high-stiffness
BOPP film, thus it is very beautiful after composite molding, and the class of integral product can get a promotion；And outermost layer is then that BOPP is thin
The polarity of film layer, the film layer is low, can be easily separated with content (plaster, facial mask, eye sticker etc.), and do not have medical fluid after isolation
Residual；Carry out be bonded using two-component polyurethane adhesive between middle layer and outer layer, safety is good, chemical resistance performance compared with
It is excellent.
Claims (1)
1. a kind of Novel release film, it is characterised in that: the release film includes middle layer (1), and the middle layer is using white
PET film or pearly-lustre BOPP film pass through adhesive phase (2) in the upper and lower surface of middle layer (1) respectively and are bonded with outer layer (3),
The adhesive phase (2) is two-component polyurethane adhesive storehouse, and the outer layer (3) is pearly-lustre BOPP film.
