PVC and PP plastic bottle caps with vent valves are specially designed closures that provide airtight sealing while allowing controlled air release. Made from high-quality PVC or PP (Polypropylene), these caps help maintain internal pressure balance, prevent leakage, and protect the contents during storage and transportation.
This product is widely used for chemical containers, liquid bottles, industrial packaging, and technical applications requiring both tight sealing and pressure ventilation.
What Are Plastic Bottle Caps with Vent Valves?
Plastic bottle caps with vent valves are closures equipped with a built-in breathable or pressure-relief valve. The valve allows air or gas to pass when pressure changes, while still keeping the container sealed against leaks and contamination.
Key design features:
Integrated vent valve for pressure control
Secure screw-on or snap-fit structure
Reliable airtight sealing performance
