Embodiment Construction
[0024] Below in conjunction with accompanying drawing, the present invention is further described;
[0025] In the accompanying drawings: a technology for removing the foam tape protective film, mainly comprising the following steps: a release film layer 1 is arranged between the tape layer 102 and the protective film layer 103; The thickness of the release film layer 1 is 0.075mm, and the release force grammage is 5g; in actual use, the release film layer 103, the foam layer 101 and the tape layer 102 are relieved of the release film through the effect of the release film layer 1. Force, easy to peel off the protective film layer 103, effectively avoid the appearance of the foam layer 101 figure 2 The circles in 104 represent the delamination phenomenon.
[0026] Also includes the following steps:
[0027] Step ①: In an environment with a temperature of 23°C-27°C and a humidity of 55-73%, first attach the tape layer 102 to the front and back sides of the foam layer 101. Du...

Abstract
The invention discloses a process for removing the protective film of a foam tape, which mainly includes the following steps: a release film layer is arranged between the tape layer and the protective film layer; the release force grammage of the release film layer is 5g; the release film layer includes a bonding segment bonded with the tape layer, and an extension protruding from the tape layer; the release force between the protective film layer and the foam layer and the tape layer is alleviated to facilitate The peeling of the protective film layer can effectively avoid delamination of the foam layer.
Description
technical field [0001] The invention relates to the technical field of foam tapes, in particular to a process for removing the protective film of foam tapes suitable for liquid crystal screens of vehicle-mounted backlight sources. Background technique [0002] Foam tape is a material with shock absorption, sound absorption and sealing effect, which is made of foam material as the base material through composite release materials.
