Method of manufacturing a bottom gusseted pouch

摘要

A method of manufacturing a roll of bottom gusseted pouches serially connected in a top-to-bottom end orientation is provided. The method comprises unwinding a pouch webbing in a first flow direction, the pouch webbing defining front and back panels of a respective pouch; inserting a gusset webbing between the panels in a second flow direction; attaching the gusset webbing to the panels to form the bottom gusseted end of the pouch; inserting a closure mechanism between the panels in a third flow direction; attaching the closure mechanism to the panels to form the resealable top end of the pouch; sealing the side edges of the panels to complete the pouch; winding the completed pouch onto the roll; and repeating these steps to form the other bottom gusseted pouches in the roll. At least one of the pouch webbing and the gusset webbing is formed of a supported film.

1. A method of manufacturing a roll of a plurality of bottom gusseted pouches with each respective pouch having a bottom gusseted end, a resealable top end and sealed first and second side edges, the plurality of pouches being serially connected in a top-to-bottom end orientation, the method comprising:
a) unwinding at least one pouch webbing in a first flow direction, the at least one pouch webbing defining front and back panels of a respective pouch; b) inserting a gusset webbing between the front and back panels in a second flow direction which is transverse to the first flow direction; c) attaching the gusset webbing to the front and back panels to form the bottom gusseted end of the respective pouch; d) inserting a closure mechanism between the front and back panels in a third flow direction which is transverse to the first flow direction, wherein the gusset webbing and the closure mechanism are in spaced parallel relation; e) attaching the closure mechanism to one or both of the front and back panels to form the resealable top end of the respective pouch; f) sealing the side edges of the front and back panels to complete the respective pouch; g) winding the completed respective pouch onto the roll in the first flow direction; and h) repeating elements a) through g) to form the other bottom gusseted pouches in the roll, wherein at least one of the pouch webbing and the gusset webbing is formed of a supported film, wherein the supported film includes at least a first film layer and a second film layer.
