Product Description
Kraft paper valve bags are specialized, high-strength packaging containers designed for industrial powders and granular materials. Made from multiple layers of durable, stretchable kraft paper combined with a PE anti-leakage inner membrane, these bags feature an automatic valve structure for filling and have become the mainstream standardized packaging solution in industries such as chemicals, building materials, and new materials.
This product supports fully automatic spiral filling and negative pressure filling assembly lines. It enables automatic air exhaust during filling and ensures the bag is fully shaped without manual sealing, significantly improving packaging efficiency while reducing damage rates and labor costs.
These valve bags are widely applicable for packaging 20 to 25 kg industrial materials like carbon black, cellulose, latex powder, tile adhesive, putty powder, dry mortar, and chemical powders. Customization options are available for layers, specifications, printing, as well as anti-leakage and anti-static features.
- High Strength and Durability: Crafted from high-strength stretch kraft paper (80-100g/m²) with multi-layered composite structure for excellent tensile strength and bursting resistance
- Sealed and Leak-Proof: Inner PE lining heat-sealed seamlessly to paper layer, perfect for ultra-fine powders like carbon black and cellulose
- Automatic Air Release: Specialized valve allows pressure relief and air ventilation during filling, preventing bag puffing
- Moisture Proof and Weather Resistant: Effective moisture blocking for humid climates and outdoor storage scenarios
- Labor-Free Sealing: Self-locking valve structure automatically seals under material pressure, eliminating manual sealing
- Regular Shape for Stable Stacking: Square-bottom forming technology ensures neat, upright shape for orderly stacking
