Product Overview
This LDPE suction nozzle spout cap is designed for flexible pouch packaging where controlled dispensing and zero leakage are non-negotiable. The cap threads onto the pouch spout fitment, creating an airtight seal that protects liquid and semi-liquid contents from contamination and moisture loss.
Common applications include juice and beverage pouches, sauce and condiment sachets, liquid detergent refill bags, personal care refill pouches, and edible oil packaging. The LDPE construction delivers the flexibility and chemical resistance required for repeated open-close cycles, while the tamper-evident ring provides visible proof of first opening
Key Advantages
