Paper Insert Valve

Valve bags feature a unique filling point located at the top corner, where materials can be introduced using air pressure, an impeller, or an auger. Once the filling process is completed, the pressure from the product inside triggers the valve to self-seal, ensuring the contents are securely contained.

A prominent option among these valve types is the Paper Tube Insert. This specific design involves inserting a paper tube into the valve opening, which provides a robust and effective sealing method. The Paper Tube Insert is particularly well-suited for products that require added stability during storage and transportation. This valve type enhances the bag's overall strength and prevents any potential spillage, making it a dependable choice for various powdery or granular substances. Its simple yet effective structure offers a secure seal, maintaining the quality and consistency of the packaged product throughout its lifecycle.
