ABSTRACT:
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.
