A flexible material for a flexible package, comprising:

• a first sheet comprising an opening panel region, the opening panel region comprising an opening boundary defining an opening to be formed in the package for accessing an interior volume of the package;
• a second sheet in the opening panel region;
• and a third sheet secured to at least a portion of the first sheet in the opening panel region, wherein the second sheet is secured to either (i) at least a portion of the first sheet in the opening panel region or (ii) at least a portion of the third sheet in the opening panel region, and wherein:
• the opening boundary is defined by lines of reduced strength in the first and third sheets, the second sheet comprises a line of reduced strength defining a flap, such that the flap is configured to separate from a remaining portion of the second sheet at the line of reduced strength to expose the opening, the opening panel region further comprises first and second opposed boundaries configured to define first and second edges of the panel of the package having the opening, the third sheet at least partially overlaps with one or both of the first and second boundaries of the opening panel region, the third sheet comprises a line of reduced strength at the one or both of the first and second boundaries of the opening panel region overlapped at least partially with the third sheet;
• and wherein the first sheet further comprises a tuck folding region sheet adjacent to the first boundary of the opening panel region, and a portion of the third sheet is secured to the first sheet in the tuck folding region, wherein, the tuck folding region is configured to be tucked inward to define the edge of panel of the package having the opening, at the first boundary.
