Detailed Description
The invention is described in detail below with reference to the figures and specific embodiments.
Example 1
A method for manufacturing a narrow strip die-cut member for preventing poor peeling, the narrow strip die-cut member, as shown in fig. 1, sequentially comprising a finished product 21 of no base glue and a self-carrying base paper 3, the finished product 21 of no base glue having a width of 8mm, the method comprising the steps of:
(1) material belt laminating: attaching the auxiliary release film 1 to the double-sided adhesive without the base material to form a material belt; wherein, no substrate double faced adhesive tape includes no substrate glue film 2 and takes body paper 3 certainly, and during the laminating, supplementary from type membrane 1 and no substrate glue film 2 laminating.
