Spout pouches have replaced rigid plastic bottles as mainstream flexible packaging for liquid & semi-viscous 

goods, thanks to lightweight structure, resealable spout and shelf-standing performance.

2. Critical Design Notes for Production

1. Spout Position & Diameter

   Corner spout saves printing space while top-center spout fits high-speed filling; thin liquids use 8–10mm small spouts, thick paste & chunky sauce adopt ≥16mm large-caliber spouts for smooth outflow.

2. Welding Reinforcement

   Reinforce the spout welding area to avoid liquid leakage under extrusion or drop impact;

   retort-grade pouches require PP spouts for high-temperature sterilization (121℃+).

3. Film Structure Matching

   High shelf-life products add AL/VMPET/EVOH barrier layer; ordinary daily refill uses mono PE structure for cost & recyclability; nylon layer improves puncture resistance for oily contents.

4. Bottom Structure

   Doypack bottom for regular 200ml–2L pouches; eight-side sealed design for large-capacity heavy-load packaging.

5. Cap Function Option

   Select tamper-evident caps for food, child-resistant caps for household chemicals per regional safety regulations.
