Product Description
Kraft paper valve bags are premium packaging solutions specifically engineered for the industrial powder sector. Manufactured from multiple layers of high-quality pure wood pulp kraft paper composite, 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 building material powders, these bags maintain structural integrity for neat stacking and efficient handling.
- Superior Powder Leakage Prevention: Unique three-layer staggered perforation process eliminates bulging and prevents powder leakage between paper layers
- High Strength Construction: Multi-layer composite virgin kraft paper provides exceptional tensile strength, tear resistance, and compression resistance
- Breathable Pressure Relief: Micro-perforation staggered venting system ensures rapid air release during filling, preventing bag deformation
- Moisture Protection: Optional high-strength PE inner liner creates effective moisture barrier to prevent caking and deterioration
- Automatic Sealing: Self-locking valve structure seals automatically after filling, preventing powder escape and maintaining clean work environments
- Environmental Compliance: Odorless, pollution-free, recyclable, and biodegradable materials meet international packaging standards
- High-Definition Printing: Multi-color printing capabilities with precise registration for enhanced brand presentation
