PALLETLESS BULK BAG
A bulk bag includes a body having sidewalls, a bottom wall and a pair of opposed lift sleeves adapted to receive lifting members for lifting the bag and contents thereof. Each lift sleeve has a first sleeve end and a second sleeve end attached together and proximate to a bottom of the sidewall to form a loop, and a portion of the sleeve extending from the second sleeve end is attached to an adjacent portion of the sidewall such that the loop maintains a substantially open position.
