Abstract
PURPOSE:To open a bag at a desired position in both of longitudinal and lateral directions when an enclosure is to be taken out, by forming a large number of C-shaped or crossed slit grooves to at least one side edge part of a narrow heat-welded part over the whole thereof. CONSTITUTION:In a hermetically closed bag 1, a large number of C-shaped or crossed slit grooves 2 are formed to a heat-welded part within a region of a distance (a): about 2-10mm from the end edge part of the heat-welded part having the slit grooves of the hermetically closed bag 1 in general corresponding to the material quality, thickness or the like of the packing material constituting said bag 1. The region where not slit grooves 2 are formed in the heat-welded part 3 is set to a part separated by a distance (b): about 2-5mm from the boundary line 5 of the heat-welded part and a heat non-welded part. By this constitution, the hermetically closed bag is opened from any part of the heat-welded part in both lateral and longitudinal directions of the bag and the bag can be easily opened only by applying slight force to a fingertip.
