Description
Self-sealing Valve Kraft Paper Valve Bags
Kraft paper valve bags are specially designed for fully automatic filling and packaging of ultra-fine powders, chemical powders, and building material granules. This innovative packaging solution is engineered to meet the specific needs of these industries with high efficiency and reliability.
Constructed using a multi-layer, high-strength, virgin kraft paper combined with an inner laminated film, the bags ensure durability and excellent protection of the contents. The incorporation of a square bottom valve structure provides enhanced stability and ease of handling during the filling process.
Replacing traditional open-mouth bags, kraft paper valve bags have become the mainstream standardized packaging choice in industries such as carbon black, silica, titanium dioxide, pigments, additives, and building materials powders. Their design optimizes automated filling operations while maintaining product integrity.
Self-sealing Valve Kraft Paper Valve Bags with High Tear Resistance and Recyclable Biodegradable Design for Heavy Duty Packaging
Key Features
  • Self-sealing Valve: Zero powder dust leakage with built-in or external valves compatible with automatic filling equipment. Automatic closure with air pressure eliminates manual sealing.
  • Square Bottom Stability: Three-dimensional square bottom provides outstanding stacking stability without package collapse, ideal for warehouse storage and container shipping.
  • Reinforced Construction: Multiple layers of reinforced paper (2-4 layers) offer excellent resistance to impact, tearing, and puncturing for durable transport handling.
  • Moisture Protection: Food-grade PE moisture-proof inner lining prevents moisture absorption, clumping, color fading, and performance degradation.
  • Automation Ready: Regular shape, uniform hardness, and accurate valve positioning compatible with domestic and international powder filling machines.
  • Brand Enhancement: High-definition flexographic and full-surface printing for company logos, product information, and export labels.
