ABSTRACT:
The invention provides a molded plastic handle for attachment to the upper end of a heavy duty olefin bag for packaging dry mix and the like, wherein the handle is provided with a hand-engaging opening, has an integrally formed depending skirt of alternating depending portions adapted to be sonically or impulse sealed to the outer surfaces of the upper edge portion of the olefin bag, with each of the depending surfaces so arranged that they do not overlap or correspond position-wise to the skirt depending element on the opposite side of the olefin bag, one of the depending portions being disposed midway along the handle, and a vertical strut being provided connecting the handle top portion to such midway depending portion. The invention also provides integrally formed reinforcing ribs at each side of the handle, on front and back faces, with downwardly bifurcated ends which extend to two end skirt portions, and thereby reinforce such end portions to equalize the load stress on the handle and top of the bag.
