Abstract

A web for use in forming envelopes has a score line extending along the web in a longitudinal direction of the web and configured to locally reduce a resistance of the web to bending about an axis coinciding with the score line. The decreased bending resistance helps to ensure that longitudinal edge regions of the web are aligned when the longitudinal edge regions are sealed to each other during formation of the envelope on automated bagging machine.
