A Spout Pouch is a preformed pouch in which a spout has been fitted. This is a (resealable) pouring, drinking or dispensing hard plastic spout that is sealed in the pouch. Stand-up pouches are often used for Spout Pouches as these pouches also stay upright once opened. Other pouch forms can also be used depending on application and use, such as Flat pouches or Quadroseal pouches. Spout Pouches can also be linked to dosing or dispensing systems.
