Application

Adhesives used for label pasting can be divided into three categories: pressure sensitive adhesive, hydrosol and water rewetting adhesive. Pressure sensitive adhesive has high initial adhesion, good adhesion, low cost, good bonding performance for most packaging materials, and the largest application in label adhesive. Pressure sensitive adhesives include synthetic rubber (SIS and SBS), EVA and acrylate, etc., and the amount of synthetic rubber pressure sensitive adhesives is large.S-1552 grade products have small hardness, good initial adhesion, and good adhesion and cohesion, suitable for all kinds of label adhesive production.
