Different Types of Valve Bags

 

Valve bags are specialized packaging solutions designed for efficient filling and secure closure, primarily used for powdered or granular products. They feature a unique valve opening that allows for quick filling without the need for additional sealing equipment.

Advantages of Valve Bags

Efficiency in Filling: The valve design allows for rapid filling without the need for additional sealing equipment, reducing labor costs.

Self-Sealing Feature: Once filled, the pressure from the contents automatically seals the bag, minimizing the risk of leakage.

Space-Saving: Valve bags are compact and can be stored efficiently compared to traditional open-mouth bags.

Customization Options: Many valve bags can be customized with printing options for branding or product information.

Types of Valve Bags

Single Layer Valve Paper Bag

Made from a single layer of paper, these bags are lightweight and suitable for products that do not require heavy-duty packaging.

Commonly used for flour, sugar, and other fine powders.

Cylindrical External Valve Paper Bag

This type features a cylindrical shape with an external valve that facilitates easy filling.

Ideal for bulk materials such as animal feed and chemicals.

Big-Bottom-Small-Valve Paper Bag

It is characterized by a larger bottom to provide stability while maintaining a smaller valve opening.

Often used in construction materials like cement and plaster.

Thumb Gap Valve Bag

This design includes a thumb gap that allows for easier handling and filling.

Suitable for products requiring manual intervention during the filling process.

Super Sonic Valve Bag

Utilizes sonic sealing technology to close the bag after filling, ensuring a secure seal without sewing.

Commonly employed in automated packaging lines due to its efficiency.

Pasted Valve Stepped End (PVSE) Bag

A multi-wall paper bag designed with a pasted valve end that helps in self-sealing once filled.

Frequently used in packaging dry flowable products like grains and fertilizers.

Applications of Valve Bags

Valve bags are versatile and find applications across various sectors:

Food Industry: Used for packaging flour, sugar, rice, and other food ingredients due to their ability to prevent contamination and maintain freshness.

Construction Materials: Ideal for cement, plaster, sand, and insulation materials where durability is essential.

Chemical Industry: Employed for packaging chemicals and minerals that require secure containment to prevent spillage or contamination.

Agriculture: Used for animal feed, fertilizers, and other agricultural products that benefit from the self-sealing feature of valve bags.
