What Are Pressure Sensitive Labeling Systems?
Pressure sensitive labeling systems are automated or semi-automated machines designed to apply self-adhesive labels to products or packaging. The labels themselves come with a pre-applied adhesive protected by a release liner, which is peeled away just before application. This method is highly versatile, accommodating various label materials, sizes, and shapes, and is suitable for a diverse range of product surfaces.
How They Work
The operational principle of a pressure sensitive labeling system is straightforward yet highly effective. Products move along a conveyor belt, and as they pass a labeling head, a sensor detects their presence. This triggers the label applicator to dispense a label, which is then pressed onto the product surface. The pressure applied ensures strong adhesion without external activators. This seamless process allows for rapid and consistent labeling at high speeds.
Key Components of a System
