ABSTRACT:
This invention relates to a tamper evident inner seal for use on bottles, jars and other types of containers. More specifically, this invention provides a means for rendering a heat or adhesive sealed liner tamper evident by enabling the liner to tear upon removal or opening, while providing a peelable seal that does not leave seal residuals attached to the container.
