  • Patent number: 4840270
    Abstract: A method for producing a label stopping area on a semirigid or flexible package having a package portion with an opening and a label flap which covers the opening. The label stopping area is such that the label flap can be lifted away from the package opening but not completely removed from the package body. The method involves treating a specific area of the package body's surface with a corona discharge so that the adhesion characteristics of the treated areas are improved. After the application of a pressure sensitive label flap, the label flap can be peeled easily up to the corona treated zone whereafter the label flap adhesion is substantially greater, thereby preventing inadvertent complete removal of the label flap from the package when opening.
