This kraft paper valve bag is crafted using a multi-layer composite process with high-quality kraft paper. It features an inner PE layer and an anti-static inner membrane, combined with a valve-filling structure, providing excellent sealing performance, high load-bearing capacity, and convenient filling.
Specifically designed for bulk powders and granules such as carbon black, chemical powders, building materials, feed, fertilizers, and mineral powders, this bag is compatible with automated filling production lines. Its stable stacking capability and resistance to damage during transportation make it a preferred choice for industrial packaging.
Moreover, the product can be fully customized according to customer working conditions, material characteristics, and printing requirements, ensuring it meets diverse industrial needs and specifications.
Featuring an inner and outer valve design, these bags are compatible with both fully automatic and semi-automatic filling machines. The filling process is swift, and once completed, the valve automatically closes without the need for additional stitching or tying.
Constructed from thick, virgin kraft paper with a conventional 2 to 4-layer composite structure, the material boasts excellent toughness and high tensile strength, making the bags resistant to tearing and impact.
An inner PE liner is integrated to block moisture and dust, preventing material clumping and fine powder leakage. Reinforced seams enhance the bag's sealing performance.
The square-bottom, three-dimensional shaping ensures the bags maintain a rigid form and self-support after filling, allowing for orderly stacking on pallets without tilting.
Made primarily from kraft paper, the bags are environmentally friendly, odorless, recyclable, and reusable, meeting domestic environmental protection standards.
The smooth surface supports multi-color printing, including logos, company names, and product information with long-lasting, fade-resistant results.
