A liner for use with a closure package and an associated container includes a pull tab that is crimped so that the tab remains in place during assembly of the closure package. The closure package includes a cap having a top wall portion and a depending skirt portion. The cap has an engaging element formed therein, that is engageable with an engaging portion of the container. The liner is formed of a laminate having a resilient material and an adhesive layer. The liner includes a central portion configured for placement in the cap abutting the top wall portion and a tab extending from the central portion. The tab is folded over so as to rest, at least in part, on the central portion. The tab and central portion define a hinge region which defines a hinge line at a juncture of the tab and the central portion. The hinge region has a deformation area formed therein, in at least two directions relative to the hinge line, to lock the tab in position resting, at least in part, on the central portion. A method of forming the closure package includes cutting a liner material to form a tab and folding the tab onto the material to form a hinge line at a juncture thereof. The liner material is hammered at about the hinge line to form a deformation generally transverse to the hinge line and extending in at least two directions relative to the hinge line. The material is then cut to form the liner central portion with the tab integral therewith. The liner is subsequently positioned in a closure cap.
