Product Description
This kraft paper valve bag is manufactured from pure wood pulp virgin kraft paper through a precise bag-making process, creating a high-performance packaging container specifically designed for granular, powdery, and flake materials. The environmentally friendly and highly durable design features an innovative valve that provides excellent sealing properties and user convenience.
During filling operations, specialized equipment can quickly complete the loading process without manual opening of the bag mouth, significantly improving packaging efficiency. The valve design effectively prevents material leakage, making it ideal for industrial-scale batch packaging requirements.
- Eco-Friendly Construction: Made from 100% natural kraft paper that is biodegradable, non-toxic, odorless, and free from harmful residues. Complies with national environmental standards and international export requirements.
- Efficient Valve Design: Features specialized inner or outer valve structures compatible with automated filling machines. Eliminates manual opening during filling, reduces labor costs, and provides automatic sealing to prevent material leakage.
- Exceptional Durability: Constructed from 100% virgin wood pulp kraft paper with strong tensile and bursting strength. Supports weights from 25 to 50 kilograms without tearing or deformation.
- Versatile Applications: Customizable with special treatments including leak-proofing and moisture resistance. Adapts well to humid, dusty, or static-sensitive environments.
- Optimal Stacking: Firm body design with excellent formability allows neat stacking up to 3-5 layers high, saving storage space and reducing logistics costs.
