Reseal with a partial perforation and method and apparatus for creating a partial perforation in a reseal

摘要

A reseal is partially perforated by stretching the reseal membrane, establishing contact between one side of the membrane and an anvil, and by effecting partial penetration of the membrane with at least one cutting edge from the other side of the membrane to a predetermined distance from the anvil. Multiple partial perforations may be made with one or more cutting edges.
