ABSTRACT:
A method and apparatus for high speed pouch or bag making from thin, extensible heat-sensitive thermoplastic film webs in which the method is applied to a continuously moving web and sealing is achieved at temperatures below the softening temperatures of the film or sealing interfaces. The method of forming an open pouch comprising the steps of continuously pulling an elongated web of pouch forming material at a constant speed along a pouch making path which extends continuously through a web slitting station, a web coating station, a web collating station, an Electron Beam curing station and a web cutting station. An elongated web is slit into first and second webs at the slitting station, a pattern of E.B. curable adhesive is applied to a first surface of the first web as it is pulled continuously through the web coating station to render the first surface bondable at a seal pattern and non-bondable in the area of the storage compartment when subjected to Electron Beam radiation. The second web is directed into a face-to-face relationship with the first surface of the first web in the collating station, the collated webs are pulled through the E.B. curing station and irradiated with E.B. radiation to bond without heat distortion the bondable areas of the webs while leaving the non-bondable areas free from securement, and pouches are cut from the bonded webs.
