Description:
Our White Label Food Grade 9.6mm and 13.5mm Screw Flip Cap Silicone Check Valves are engineered with precision from FDA- and LFGB-compliant liquid silicone rubber (LSR), ensuring safe, hygienic, and leak-proof dispensing performance. Manufactured via high-precision liquid silicone injection molding, these valves feature a one-way slit-membrane design that allows controlled flow of liquids such as sauces, condiments, honey, oils, or syrups—while reliably preventing backflow, leakage, or contamination.
Designed to integrate seamlessly into screw flip caps, the valves are available in 9.6mm and 13.5mm diameters, making them compatible with a wide range of packaging formats. With temperature resistance from –40 °F to 450 °F, long-term elasticity, and chemical stability, these valves provide durable performance for both household and commercial food packaging applications.
We offer full OEM and white-label services, including custom valve geometry, slit configuration, hardness adjustment, and logo/branding solutions, enabling your packaging to stand out with superior dispensing performance.
