Abstract
A carton-liner assembly comprises a carton and a liner constructed and arranged for placement within the carton. The carton includes opposing top and bottom walls, opposing front and back walls, and opposing side walls. The liner includes a front panel and opposing side panels for fitting the liner within the carton. The liner front panel has an outer surface adjacent to an inner surface of the carton front wall. The carton-liner assembly further comprises a plurality of embossments integral with the liner and a plurality of debossments integral with the carton. The embossments and debossments are arranged to increase the thickness of the assembly in regions spaced from relatively thick portions of the assembly while the assembly is in flattened tubular form during production so as to counterbalance the thick portions of the assembly, thereby improving stackability of the assembly while the assembly is in flattened tubular form.
