Spout pouch material structure guide for juice, sauce, puree and liquid food.
Spout pouch material structure affects sealing strength, leakage resistance, filling compatibility and shelf life.
Leakage around spout, weak side sealing, pouch deformation after filling, material not suitable for liquid product.
1. Using standard film for hot filling. 2. Not confirming spout size. 3. Ignoring filling temperature impact. 4. Not testing welding strength. 5. Choosing only based on cost.
PET/PE for ambient juice. PET/NY/PE for puncture resistance. PET/VMPET/PE for extended shelf life. PET/AL/NY/PE for maximum barrier. NY/PE for frozen products.
Spout welding strength, heat sealing, leakage test, pouch stability and material structure confirmation before shipment.
Product type, filling volume, pouch size, spout position, cap size, filling temperature, quantity and artwork.
PET/PE is commonly used for ambient juice.
It depends on material structure.
Welding strength, sealing temperature and size matching should be confirmed.
Yes, based on pouch design and filling method.
