[0002] At present, self-adhesive materials have been widely used in various industries, among which the most common product is self-adhesive labels. Traditional self-adhesive labels are generally produced by combining the base paper and the face paper together. When in use, the face paper can be peeled off from the base paper and pasted on the corresponding items. In order to further reduce the production and use costs, it is considered to adopt a new type of baseless self-adhesive label, that is, a self-adhesive structure without a base paper.
[0003] In the prior art, in the process of producing linerless adhesive tape, the linerless adhesive tape after processing is often required to be rolled and slit by special equipment.
