Technical FAQ: Paper Valve Bags
Q: What is the sealing mechanism of a Paper Valve Bag?
A: The bag is designed with a internal or external valve sleeve. During filling, the product enters through this sleeve. Once the bag reaches capacity, the internal pressure of the material flattens the sleeve against the bag wall, creating an automatic, secure seal.
Q: What are the primary benefits for industrial automation?
A: - High-Speed Packing: Perfectly suited for automatic rotary and inline packers.
- Stability: The rectangular "brick" shape allows for taller, safer pallet stacks.
- Reduced Waste: Self-sealing prevents material spillage during transport.
Q: How do you provide moisture protection for powders?
A: We use multi-wall construction, typically 2 to 4 plies of high-performance kraft paper. For moisture sensitivity, we can insert a PE-free film layer or use PE-coated paper to create a robust barrier against humidity and water vapor.
Q: Are there different types of valves available?
A: Yes. We offer Internal Valves for standard automatic sealing and External Valves (extended sleeves) which can be manually folded or ultrasonically heat-sealed for a 100% sift-proof finish.
