Tuck-In Sleeve

Valve bags are specifically designed with a filling point located at the top corner, allowing materials to be easily introduced using air pressure, an impeller, or an auger. As soon as the filling is complete, the pressure from the product inside automatically triggers the valve to close, ensuring the contents are securely contained within.

One notable option among valve types is the Tuck-In Sleeve. This design features a simple yet effective folding mechanism, where a flap is manually tucked into the opening after filling. The Tuck-In Sleeve is ideal for products that require a straightforward yet dependable sealing method. It provides a tight closure that prevents any leakage or spillage, making it a practical choice for a variety of powdered or granular materials. This type of valve is especially appreciated for its ease of use and flexibility, offering a solid seal without compromising the integrity of the packaged product during transit and storage.
