Abstract:
A Z-fold mailer business form intermediate comprising:a sheet or web of paper having first and second faces, first and second end lines substantially parallel to each other, and first and second side lines substantially parallel to each other and substantially perpendicular to said first and second end lines;first and second fold lines extending substantially parallel to each other and to said end lines for dividing said sheet or web between said end lines, into first, second and third panels;first and second lines of weakness spaced from but adjacent and substantially parallel to said first and second side lines, defining first and second tear-off edges in a mailer produced from said intermediate;a first pattern of pressure activated cohesive comprising spaced distinct sealing elements disposed adjacent said first end line on said first face, and a second pattern of pressure activated cohesive which cooperates with said first pattern when said intermediate is Z-folded about said fold lines to form a mailer;said second pattern disposed adjacent said second fold line on said first face;a third pattern of pressure activated cohesive comprising spaced distinct sealing elements disposed adjacent said second end line of said second face and a fourth pattern of pressure activated cohesive which cooperates with said third pattern when said intermediate is Z-folded about said fold lines to form a mailer, said fourth pattern disposed adjacent said first fold line on said second face;said first and second pattern elements shaped and dimensioned and positioned with respect to said third and fourth pattern elements so that they substantially do not overlap in roll or stack form;fifth and sixth patterns of pressure activated adhesive each comprising spaced distinct sealing elements disposed adjacent said first and second lines of weakness respectively in said tear-off edges on said first face and positioned so that the elements thereof cooperate with each other when said intermediate is Z-folded about said fold lines;seventh and eighth patterns of pressure activated adhesive each comprising spaced distinct sealing elements disposed adjacent said first and second lines of weakness respectively on said second face and positioned so that the elements thereof cooperate with each other when said intermediate is Z-folded about said fold lines; andsaid fifth and seventh, and said sixth and eighth, patterns positioned and spaced from each other in a dimension substantially parallel to said end edges, and so that said patterns substantially do not overlap in roll form and do not overlap in stack form;wherein at least the majority of said elements are rectangular in shape, having a length and width;wherein said elements in at least some of said fifth through eighth patterns are spaced from each other a distance greater than said length.
