ABSTRACT:
The easily openable synthetic resin bag substantially comprises a) a bag body having in an overlapped state front and rear walls of substantially rectangular shape, and a bottom wall interposed between the lower ends of the front and rear walls and having opposite side edges folded down in an inverted V-shape, and b) a tear string heat sealed on the inner side of the rear wall along an opening line at the upper end of the bag body and having opposite end portions thereof heat sealed in gripped state between corresponding portions of the lateral marginal seal portions of the bag body; the bag body having a width gradually broadened in a tapered fashion from the upper to lower end thereof. Accordingly, when the bag body is packed with a filling material and undergoes reductions in width in bag portions packed with the filling material, such bag portions still have a width which substantially equivalent to or which is not markedly smaller than the width of the unfilled upper bag portions. Therefore, when put on a shelf or a similar support surface, the bag can stand there in a quite stabilized state.
