Enhance efficiency with our Carbon Black Double-layer Labyrinth De-aeration PE Valve Bags. Engineered for fine carbon black powders, the staggered de-aeration channels rapidly vent air to ensure fast filling, zero dust leakage, and compact palletizing. Durable PE construction provides superior moisture barriers and puncture resistance for safe storage.
Material:
High-density co-extruded PE (Polyethylene) multi-layer film, engineered for heavy-duty pressure, superior tear/puncture resistance, and total moisture isolation for micro-fine carbon black powders.
Core Features:
Double-Layer Labyrinth De-aeration: Features an integrated inner and outer layer structure with offset, maze-like exhaust channels. Rapidly releases trapped air during high-speed filling while preventing dust leakage and stopping ambient air backflow.
Self-Sealing Valve Port: Fitted with an internal valve sleeve that automatically seals under internal powder pressure, ensuring zero leakages during filling, dropping, and handling.
Anti-Slip Array Texture: Embossed surface pattern engineered into the outer film layer maximizes friction between bags, guaranteeing stable, non-slip palletizing during long-distance transport.
Complete Environmental Protection: Durable, wear-resistant PE construction provides a 100% moisture-proof barrier to keep carbon black completely dry and free from external contamination.
Classification:
By valve structure (internal sleeve, extended sleeve, or ultrasonic seal), de-aeration pattern (double-layer labyrinth, micro-perforated filter, or offset vent), and surface finish (embossed anti-slip array or smooth matte).
Application Areas:
Rubber Tire & Industrial Rubber Manufacturing: Clean, dust-free packaging for high-purity carbon black, silica additives, and rubber reinforcing fillers.
Masterbatch & Plastics Industry: Bulk supply packaging for black masterbatches, high-pigment powders, and conductive polymer compounds.
Paints, Coatings & Inks Production: Reliable, leak-proof packaging for fine carbon black pigments used in specialty printing inks and industrial coatings.
