Corner Valve Paper Valve Bags with Moisture Resistant Coating
Product Overview

Kraft paper valve bags are premium packaging solutions engineered for industrial powder applications. Constructed from multiple layers of pure wood pulp kraft paper laminated together, these bags feature a square bottom valve structure compatible with fully automatic filling equipment.

Designed for packaging dry ultra-fine materials including carbon black, silica, rubber additives, chemical powders, and construction materials, these bags maintain structural integrity for neat stacking while offering exceptional impact and compression resistance.

Kraft paper valve bags for industrial powder packaging
Key Features
Superior Leak-Proof Performance

Advanced three-layer staggered perforation technology prevents powder leakage through paper seams, eliminating issues with carbon black darkening and white carbon black whitening.

Exceptional Strength & Durability

Multi-layer lamination using high-toughness virgin kraft paper ensures excellent tensile strength, tear resistance, and pressure durability for reliable transport and stacking.

Optimal Breathability

Precision micro-perforations enable rapid air evacuation during filling, preventing bag bulging and enabling neat, attractive stacking on automated high-speed lines.

Moisture Protection

High-strength PE inner film provides superior sealing to isolate air and moisture, preventing absorption, dampness, and caking for long-term storage stability.

Automatic Sealing

Self-locking valve structure automatically seals upon filling completion, preventing fine powder dust escape and maintaining clean production environments.

Eco-Friendly Compliance

Odorless, pollution-free, recyclable, and biodegradable materials meet domestic and international environmental standards for export markets.

Technical Specifications
Material Standards

Manufactured from high-quality, fully wood pulp stretch-thickened kraft paper with smooth surfaces free from oil stains, holes, and brittleness. Available in double-layer, triple-layer, or quadruple-layer structures with optional PE inner film laminate.

Process & Structural Standards

Integrated square glued bottom with reinforced weight distribution. Neat, appropriately tight valve mouth compatible with both fully automatic and semi-automatic filling machines. Size deviations strictly controlled within ±5mm.

Performance Indicators
Tensile Strength Multi-layer composite provides uniform strength for full-load stacking and transportation
Air Permeability Offset micro-perforations enable quick air release, preventing deformation
Sealing Performance Self-sealing valve prevents leakage of ultra-fine powders and dust emissions
Moisture Resistance Inner film effectively blocks moisture, preventing powder clumping
Impact Resistance Resistant to drops and compression, minimizing damage during logistics
Anti-Static Performance Optional anti-static treatment for carbon black powder applications
Standard Specifications

Available in conventional load capacities: 10kg, 15kg, 20kg, 25kg, 40kg, and 50kg. The 25kg specification is mainstream for industrial powders. Custom sizes supported for non-standard dimensions.

Application Areas

Carbon Black Industry Specialized packaging for rubber, pigment, conductive, and pyrolysis regenerated carbon black with anti-static and anti-penetration technologies.

Silica Industry Optimized for precipitated and fumed silica materials with staggered perforations preventing leakage and moisture-induced clumping.

Rubber & Chemical Powders Suitable for rubber additives, zinc oxide, kaolin, filler powders, resin powders, and pigment powders.

Building Materials Robust packaging for putty powder, dry mortar, tile adhesive, gypsum powder, and cement powder with strong load-bearing capacity.

Food & Feed Grade Food-safe packaging for starches, food additives, and feed carrier powders in compliance with relevant standards.

Automated Production Designed for high-speed filling lines without bag jamming or bulging, enhancing production efficiency.

Export Packaging Engineered to withstand maritime humidity, compression, and handling stresses for international markets including Southeast Asia, Middle East, and Philippines.
