METHOD OF FILM CREASE ELIMINATION AND PATCH BAG WITHOUT CREASE WITHIN LAY-FLAT BAG

A process for removing creases from a film eliminates a problem in the quality o f the heat seal for a patch bag having at least a segment of one or more bag side edges (or the bag bottom edge)covered by one or more patches. The film creases are removed by inflating t he film tubing which is later c...

Zusammenfassung:	A process for removing creases from a film eliminates a problem in the quality o f the heat seal for a patch bag having at least a segment of one or more bag side edges (or the bag bottom edge)covered by one or more patches. The film creases are removed by inflating t he film tubing which is later converted to a bag, heating regions containing the creases with a heati ng means to a temperature which, in combination with the pressure within the inflated tubing, causes the creases to relax. The heated crease-containing regions are then cooled and the inflated tub ing is deflated and wound up in a new configuration in which at least one patch covers at least one side edge or the bottom edge.
