ABSTRACT:
A container packaging method is provided which ensures a sealing ability and yet has an easy opening ability. Between a container edge and a film covering an upper opening face of a container, a strip seal, having a portion sealed partially weakly at an outer side portion of a corner of the container edge, is formed and a double line seal is formed on the strip seal. An outer line seal has its corner end projected toward an outer side edge of the corner of the container edge. The outer line seal and an inner line seal are connected by a seal connection formed in a diagonal direction of the container. The inner line seal has its inner side edge at the corner of the container edge be of a cornered shape.
