Drink pouches and methods for producing them

摘要

There are disclosed methods of making drinking pouches constructed from at least two panels of flexible laminate web material, at least a first panel thereof having a structural layer ( 21 ), a barrier layer ( 22 ) and a sealant layer ( 23 ), the sealant layer having a first thickness. An exemplary method comprises the steps of punching a hole ( 19 ) through the first panel, extruding molten sealant onto the sealant layer ( 24 ), thereby occluding the hole, colling the first panel and joining the panels together to thereby form a drinking pouch.
