Description
Customization and Valve Types Paper Valve Bags
Designed to Meet Diverse Packaging Needs with Custom Logo Options
Product Overview
The kraft paper valve bag is a high-strength packaging container specifically designed for industrial powders and granular materials. It is made from multiple layers of durable, stretchable kraft paper combined with a PE anti-leak inner film. This composite structure, along with a fully automatic filling valve design, makes it a leading standardized packaging solution in industries such as chemicals, construction materials, and new materials.
This product supports fully automatic spiral filling and vacuum filling production lines, enabling automatic air release during filling and ensuring bags are automatically shaped and filled to capacity. It eliminates the need for manual sealing, significantly improving packaging efficiency while reducing damage rates and labor costs.
The kraft paper valve bag is widely suitable for packaging 20 to 25 kg industrial materials such as carbon black, cellulose, latex powder, tile adhesive, putty powder, dry mortar, and chemical powders. It can be customized based on requirements concerning the number of layers, size, printing, and features like anti-leakage and anti-static properties.
