Abstract:
A method of making a flexible package for containing material and permitting the material to be discharged therefrom, said method comprising the steps of:a) continuously moving two webs of flexible material along a pre-determined path of movement with said two webs being juxtaposed so that the opposite side edges of said moving webs are located adjacent one another; b) continuously depositing an elongated selectively openable fastening strip between said two webs in the direction of travel of said web and sealing said fastening strip to said one web at a position adjacent one of said side edges thereof; c) joining together the adjacent portions of said two webs along the other of said side edges thereof to provide a closed bottom side of said flexible package; d) sealing said two webs together along seal lines located in spaced parallel relation to one another and extending transverse to said path of movement to provide two opposite side portions for said flexible package; e) crushing a portion of said elongated fastening strip extending between said seal lines to cause such portion to be rendered non-openable; f) forming a handle opening extending through said two webs at a position adjacent said crushed portion of said fastening strip and between said fastening strip and said closed bottom side of said flexible package.
