ABSTRACT:
In the manufacture of a package used to hold liquids, wherein the package has a perforated or punched-out rip-out opening or a point at which a drinking straw can be inserted, wherein a cardboard web is coated on one or both sides, printed and processed into packages, the improvement which comprises advancing the web past a station prior to coating, and at such station punching or perforating the web at predetermined intervals at predetermined points while simultaneously applying to or impressing into the web register marks, whereby such register marks serve to ensure proper location of the subsequently applied print relative to the punched or perforated points. This differs from prior processes in that it involves perforating the cardboard web prior to both coating and printing, and thus is a simpler process resulting in a superior product.
