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. |
