Multi-layer kraft paper valve bags are premium automated packaging products specifically designed for industrial powders and granular materials. These bags feature a three-paper and one-film composite structure with square valve and three-dimensional square bottom design, optimized for high-speed filling using fully automatic filling machines.
Key Features
Dust-Free Filling with Zero Powder Leakage
Specialized valve design compatible with automatic impeller-type and gravity-type filling machines ensures rapid air exhaust without powder dust spillage.
High Strength and Durability
Multi-layer kraft paper composite structure with reinforced inner film provides excellent tensile, puncture, and drop resistance.
Moisture-Proof and Anti-Oxidation
Built-in waterproof and barrier inner membrane blocks air and moisture penetration, preventing material deterioration.
Neat Formation and High Storage Efficiency
Glued flat-bottom technique maintains square, upright shape for stable stacking and optimal warehouse space utilization.
Cost Reduction and Efficiency Improvement
Strong adaptability to automated filling processes eliminates manual stitching and sealing, saving labor costs.
