For alcohol spout pouches, the material structure must ensure high barrier, chemical resistance, and leak-proof sealing, especially because ethanol can be aggressive to some plastics and easily evaporates. Here’s a breakdown of the best material recommendation for alcohol packaging
Alcohol & Wine Spout Pouch Bags
Wine pouches are heavy-duty large volume liquor and wine packaging spout/fitment pouches. These pouches are with both top and bottom gusset, add an easy pour tap and fitment on the pouch front, normally made in 4 or 5 layers high barrier aluminum laminated material.
Recommended Material Structure for Alcohol Spout Pouches
Option 1: High-Barrier Laminate (Best Overall Performance)
PET / AL / NY / PE (or PET / AL / PET / PE)
- PET: Print layer with good mechanical strength and temperature resistance
- AL (Aluminum foil): Excellent oxygen, moisture, and light barrier to preserve alcohol content
- NY (Nylon): Puncture resistance and toughness
- PE (Polyethylene): Inner seal layer, chemical-resistant and flexible
✔️ Best for:
- Spirits (vodka, whiskey, gin, etc.)
- Cocktails, wine
- Shelf-stable and long-term storage
Why Wine Pouches?
- The pouch is very thick so it is not easy in pouch-making;
- The sealing will be a problem with so many edges and corners on the pouch;
- Tap added by hand is hard to control in the right middle of the hole;
- The mold cost is very high in each new volume and shape customization;
- Not all machine can add taps on pouch automatically and perfectly;
