What is the standard of self-adhesive materials?

The plastic you are talking about is actually PET, PE, OPP film and other materials. Self-adhesive materials, also known as self-adhesive materials, pressure-sensitive adhesive materials or self-adhesive, are the basic materials for label printing. Widely used in industrial production, daily necessities and other identification labels. All kinds of PET films, PVC films and PE films can be used as self-adhesive materials. Basic components of self-adhesive printing materials. It is mainly composed of surface printing layer, adhesive layer and peeling layer.

The firmness of (1) surface material label is the key to bidding. Therefore, the surface material is required to have certain strength and hardness, and the firmness of the label is related to the thickness of the material and the area of the label, so when using the soft film material, the thickness should be appropriately increased. Tissue paper material, such as 60 ~ 70g/m.

(2) The peeling force, also called peeling force, is the force when the label leaves the backing paper. The release force is related to the type and thickness of the adhesive and silicone oil coating on the surface of the backing paper, and also to the environmental temperature when labeling. The release force is too small, and the label is easy to separate from the backing paper during transportation, that is, the label falls off; However, the release force is too great, so it is difficult for the label to leave the backing paper and the label cannot be issued. All technical indexes should be comprehensively controlled to make the parting force within a reasonable range.
