Abstract
A method and apparatus for formation of a preformed bonded pull tab over a reseal liner is disclosed. The pull tab seal layer of material is bonded together with a reseal liner layer of material for insertion into a closure. The pull tab on the pull tab liner seal is formed prior to combination of the two layers and is folded backwards between the two layers of material. Thus, after combining the two layers, punching out the closure liner and insertion into the closure, the reseal liner is separated from the pull tab seal and the pull tab seal is adhered to the rim of the container. Only one punch press step is required for forming the closure and container seals and insertion of the members into the closure. By forming the pull tab prior to combining the two layers, an assembly of the pull tab and reseal liner is made more efficient and less time consuming.
