Background
As shown in fig. 1, the raw material of the double-sided adhesive tape with the double-sided self-contained release film is a common material for producing a double-sided adhesive tape die-cutting piece, and during production, the double-sided adhesive tape is produced on a carrier by using the non-easily torn self-contained release film as the carrier, and then a layer of the easily torn self-contained release film is adhered to the surface without the release film for protection. Like this, will lead to the viscidity difference on double faced adhesive tape two sides, it is difficult for tearing from taking that one side from the type membrane to paste, and the viscidity that is difficult for tearing the face promptly can be than pasting from taking that one side that the type membrane easily torn the face from the area, and it is bigger to easily tear a face viscidity promptly.
Fig. 2 is a conventional double-sided adhesive tape die-cutting member, in which the second tape release film is a carrier tape of a final product, and it can be seen that the handle release film is attached to the original side of the double-sided adhesive tape to which the non-easy-to-tear self-carrying release film is attached, i.e. the non-easy-to-tear side is attached; when the die-cutting tool is used by a customer, the second material belt of the die-cutting part is torn off from the release film, then the adhesive is pasted on a workpiece, such as an FPC (flexible printed circuit) board, then the handle is torn off from the release film, and then the operation of the next procedure is carried out.
Because the viscidity of the surface which is not easy to tear and the handle from the type film is possibly larger than the viscidity of the surface which is easy to tear and the workpiece, the separation probability of the surface which is not easy to tear and the handle from the type film and the separation probability of the surface which is easy to tear and the workpiece have comparability. Therefore, when the handle is torn away from the release film in the double-sided adhesive tape die cutting piece, the phenomenon that the double-sided adhesive tape is separated from a workpiece often occurs, abnormity occurs, and customer operation is influenced. This is also a frequent disadvantage of handled double-sided adhesive die cuts.
