Problems solved by technology

However, in the technical solution of this invention, since the adhesive will be fixedly bonded to the partition when it is cured, it cannot be peeled off after cutting. It is necessary to attach the partition to the adhesive layer after the adhesive is cured, but the volume of the adhesive will decrease after curing. Shrinkage will cause the substrate to deform and affect the printing effect of the substrate

Abstract

The invention relates to a manufacturing method for a self-adhesive label. The method comprises the following steps that (1) a label baseplate is coated with a first adhesive layer, wherein the heightof the center of the first adhesive layer is higher than that of the two sides; (2) the two sides of the first adhesive layer are coated with a second adhesive, the height of the two sides is lower than the middle height, and the second adhesive is an electron beam (EB) solidified adhesive; (3) the exterior of the second adhesive is provided with a fusion membrane layer; (4) a partition part is attached to the exterior of the fusion membrane layer, and the partition plate and a substrate are printed; (5) an electron beam penetrates through the partition plate and irradiates the second adhesive, so that the second adhesive is mixed with the first adhesive for solidifying; (6) the fusion membrane layer is heated, so that the fusion membrane layer is fused; (7) after cooling, a mixed solidified part of the second adhesive and the first adhesive is cut off; (8) the cut solidified part is stripped.

Description

technical field [0001] The invention relates to a label making process, in particular to a self-adhesive label making process. Background technique [0002] The label provides people with the attributes to identify the product, and it reflects the inherent quality of the product with its excellent design and exquisitely decorated printing. Labels have a long history and there are many types, but self-adhesive labels are currently a widely used label, and they are commonly used materials in the packaging and decoration industry. [0003] Self-adhesive labels, also known as self-adhesive labels, instant stickers, sticky notes, etc., are a composite material made of paper, film or special materials as the fabric, adhesive on the back, and silicon-coated protective paper as the base paper. After printing and After processing such as die-cutting, it becomes a finished label. When applied, it can be manually pasted on the surface of various substrates, or it can be automatically...
