ABSTRACT:
A bag for storing material in liquid or particulate form, comprising four side walls and top and bottom walls that are integral extensions of the four side walls, is characterized by an additional single or multi-ply sheet that overlies and is sealed to one side of said bag, said sheet material being adapted to be partially separated from itself so as to form a flap at the top end of the bag that can be gripped for use in supporting the bag as it is being drained of its contents via a drain located at the bottom end of the bag.
