Abstract
The utility model relates to an ultra-thin PET is from type membrane, it is including the polymer protection film, compound glue, PET membrane and the release agent layer that connect gradually, the PET orientation the one side on release agent layer is the corona face, polymer protection film strippably paste in the PET membrane. The polymer protective film is attached to the PET film so as to protect the PET film, so that the PET film is not easy to damage in the baking and drying process, the required release agent can be directly coated, and the purpose of manufacturing the ultrathin release film is achieved.
Description
Technical Field
The utility model relates to a from the type membrane field, especially relate to an ultra-thin PET leaves type membrane.
Background
The thickness of the existing release film is 25-125 microns, and because electronic parts are generally small and have complex structures, the release film is required to be ultrathin, but because the ultrathin PET is directly baked and dried, the PET can be easily stretched and deformed and even directly broken, and the release film is not beneficial to mass production.
Disclosure of Invention
An object of the utility model is to provide an ultra-thin PET is from type membrane to solve the problem that proposes in the above-mentioned background art.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides an ultra-thin PET is from type membrane, its includes the polymer protection film, compound glue, PET membrane and the release agent layer that connect gradually, PET orientation the one side on release agent layer is the corona face, the polymer protection film paste with striping in the PET membrane.
Furthermore, the thickness of the polymer protective film is 40-70 μm.
Further, the thickness of the PET film is 3-20 μm.
Further, the thickness of the release agent layer is 0.1-0.5 mu m, and the release force is 10-100 g/inch.
Further, the polymer protective film is made of PET or PE materials.
The utility model has the advantages that: the polymer protective film is attached to the PET film so as to protect the PET film, so that the PET film is not easy to damage in the baking and drying process, the required release agent can be directly coated, and the purpose of manufacturing the ultrathin release film is achieved.
Drawings
The figures further illustrate the invention, but the embodiments in the figures do not constitute any limitation of the invention.
Fig. 1 is a schematic structural diagram according to an embodiment of the present invention.
Detailed Description
As shown in fig. 1, an embodiment of the present invention provides an ultra-thin PET release film, which includes a polymer protective film 1, a compound adhesive 2, a PET film 3 and a release agent layer 4, wherein the thickness of the polymer protective film 1 is 40-70 μm, and the polymer protective film 1 is made of PET or PE material. The thickness of the PET film 3 is 3-20 mu m, the surface of the PET facing the release agent layer 4 is a corona surface, the composite adhesive 2 is low in viscosity and easy to adhere to the polymer protective film 1, and the polymer protective film 1 is detachably adhered to the PET film 3. The thickness of the release agent layer 4 is 0.1-0.5 mu m, and the release force is 10-100g/inch, wherein the release force can be adjusted according to actual requirements. In the actual production process, firstly, the polymer protective film 1 is matched with the composite adhesive 2 and is adhered to the PET film 3, then corona is carried out on one surface, far away from the polymer protective film 1, of the PET film 3, so that the PET film 3 generates a corona surface, then a release agent with the thickness of 0.1-0.5 mu m is coated on the corona surface, so that a release agent layer 4 is formed, and then the release agent layer 4 is baked and dried. When the film needs to be used, the polymer protective film 1 is peeled off to obtain the ultrathin PET release film. Through inciting somebody to action polymer protection film 1 pastes thereby right on the PET membrane 3 protects, can make PET membrane 3 is difficult destruction in the drying process that toasts, can directly coat required release agent again, reaches the purpose of making ultra-thin release film, just ultra-thin PET peels off when using from the advantage of type film polymer protection film 1 just can let PET membrane 3's thickness is enough thin, with sticky tape laminating cross cutting processing back, and the docile nature is fine, can not lead to edge release agent membrane and the separation of face of glue because of cross cutting processing piece back easily, sheet course of working, use the sheet, shift transportation etc..
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
