Zusammenfassung:	A flexible laminate, packaging structure and method comprising an outer structure, an inner structure, and a pressure sensitive adhesive layer adhesively joining the outer and inner structures to form a laminate. At least one outer line of weakness is formed in the outer structure, wherein the at least one outer line of weakness terminates in at least one tear receiving element adjacent an opening end of the laminate. A tab is defined by at least one line of weakness formed through both the outer structure and the inner structure, wherein the at least one tab line of weakness terminates in at least one tear propagating element. A second inner line of weakness is formed in the inner structure, wherein the second inner line of weakness is disposed between the at least one tear propagating element of the tab and the at least one tear receiving element of the at least one outer line of weakness.
