Spouted Stand-Up Barrier Pouch Sauce Packaging Pouch

This is a spouted stand-up pouch built for liquid and semi-liquid foods. The factory specification gives a 140-micron laminate of OPP, PET, aluminium foil and PE. The foil layer is the barrier: it blocks oxygen, moisture and light, which protects flavour and colour in sauces, purees and pastes. The OPP outer layer takes print and resists scuffing; the PE inner layer is the heat-seal and food-contact layer. The base gusset lets the pouch stand on a shelf, and the spout is welded into the top seam so the pack can be poured and resealed.

These pouches suit sauces, condiments, purees, baby food, soups and liquid concentrates. They run on vertical form-fill-seal lines with a spout-insertion station, or they can be supplied pre-made for hand or semi-automatic filling. Fill through the spout, then cap and seal; the base gusset needs a clean fold before the final seal. A spout with a screw cap is standard on this format. A zipper makes less sense here because the spout is the reclose point. A window is possible but breaks the foil barrier, so it is usually limited to a small clear patch. If recyclability matters more than shelf life, a mono-material PE or PP structure is the better route; it will not match foil for oxygen and light barrier, so check the required shelf life first.
