The self-adhesive material structure is superficially composed of three parts, namely surface material, adhesive and backing paper. Glass cardboard self-adhesive wholesale manufacturer will give you a detailed introduction. , Surface material is the surface material, which is a material that accepts printed graphics and text on the front, accepts adhesive on the back, and is finally applied to the object to be pasted. Generally speaking, any flexibly deformable material can be used as a fabric for self-adhesive materials, such as commonly used paper, film, composite foil, various textiles, thin metal sheets, and rubber.
, Adhesive Adhesive is the medium between the label material and the bonding substrate, which plays a connecting role. According to its characteristics, it can be divided into two types: permanent and removable. It comes in a variety of formulas, suitable for different surface materials and different occasions. Adhesive is the most important component in self-adhesive material technology and the key to label application technology.
. The function of the bottom paper is to receive the release agent coating, protect the adhesive on the back of the surface material, and support the surface material so that it can be die-cut, waste discharged and labeled on the labeling machine. Like the surface material, the uniformity and strength indication of the thickness of the backing paper are not only related to the printing performance, but are also important indicators that determine the uniformity of die-cutting, the speed of waste discharge, and the edge breakage of the paper.
