a web for the manufacture of fluid filled units with a novel machine and process is disclosed . the web includes an elongate heat sealable , flattened plastic tube comprised of face and back imperforate layers . the layers are imperforately joined together along spaced side edges . the layers include superposed longitudinal lines of weakness disposed generally transversely midway between the side edges . the web has longitudinally spaced , pairs of transverse seals . each transverse seal extends from a respective side edge to an end near but spaced from the longitudinal lines of weakness . the transverse seal pairs include transverse lines of weakness extending from one side edge to the other generally centrally of each seal in a longitudinal direction . the side edges , transverse seals and lines of weakness together delineating two oppositely oriented strings of pouches with each pouch having three imperforate sides and a centrally located fill opening at its fourth side . the transverse lines of weakness are spaced slightly more than one half the circumference of a cylindrical fluid fill nozzle used to fill the pouches such that the web closely surrounds the nozzle during pouch fluid filling .
