Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments.
Examples
Referring to fig. 1-4, a die cutting process for controlling the size of a mailer area of a easy-to-pull adhesive at least comprises the following steps: firstly, taking a backing film 10 as a substrate, compounding a layer of release film A30 on the adhesive surface of the backing film, compounding a layer of Mylar A20 on the non-release surface of the release film A30, and die-cutting the Mylar A20 and the release film A30 together on the backing film 10 to obtain a first semi-finished product;
and a second step of compounding the easy-to-draw glue 40 on the first semi-finished product obtained in the first step, tearing off the original film or original paper of the easy-to-draw glue 40, compounding the release film B50 with the easy-to-draw glue 40, compounding a layer of Mylar B60 on the release surface of the release film B50, and die-cutting the Mylar B60 on the release film B50 to obtain a second semi-finished product, wherein the release film B50 in the second step can not be cut in the actual die-cutting process, and the easy-to-draw glue 40 can be prevented from being die-cut when the release film B50 is arranged in the die-cutting process, so that the Mylar size area of a product meets the designed requirement, and compared with the traditional die-cutting process, the die-cutting process can ensure the size of the Mylar area of the easy-to-draw glue 40, reduce the die-cutting process, reduce the production cost and improve the yield.
