Pattern Coating - What is pattern coating?

Definition of PATTERN COATING:

This term refers to the application of an adhesive onto pressure sensitive label stock where the adhesive is arranged into a pattern of strips so that the adhesive layer alternates between strips of adhesive and “blank” spaces with no adhesive. Also known as strip coating or zone coating, this term usually refers to adhesives that are applied parallel to the machine direction and across the width of the stock, although it can also refer to arrangements that are not related to web direction.

Pattern coatings are usually used to create dry lift areas on a label (see: dry edge/pull tab) or to allow different types and/or strengths of adhesives to be used on the same label.

The same technique can be repeated for the release coating on the backing sheet of a pressure sensitive label construction so that there are areas that have no adhesive and no release coating; in these areas, the face material is permanently bonded to the backing sheet so that only certain portions can be removed from the construct (for example, this could be used to create a form of integrated labels, where only part of the sheet is a functional label (or labels) that can be removed).

Pattern coating adhesives are also used when manufacturing medical supplies, such as plasters and wound dressings, which are applied directly onto the skin. Using a pattern coating of adhesive means that there are voids in the adhesive layer that allow air to reach the skin while a plaster or dressing is worn.

Plasters may use a pattern coating of adhesive to allow air to reach the skin while a plaster is worn.
