Product Description
This kraft paper valve bag is crafted using a multi-layer composite process with high-quality kraft paper. It features an inner PE or anti-static film lining and a valve filling structure, ensuring excellent sealing performance, high load-bearing capacity, and convenient filling operations.
Specifically designed for bulk powders and granular materials such as carbon black, chemical powders, building materials, feed, fertilizers, and mineral powders, this valve bag is well-suited for automated filling production lines. Its stable stacking and robust construction help prevent damage during transportation.
As a leading choice in industrial packaging, this product can be fully customized to meet customer-specific working conditions, material characteristics, and printing requirements, providing a tailored solution for various applications.
Our packaging features an inner and outer valve design, compatible with both fully automatic and semi-automatic filling machines. This design enables rapid filling operations, as the valve automatically seals upon completion without the need for additional stitching or tying. This not only saves time and labor but also significantly boosts production efficiency in the workshop.
Made from premium thickened kraft paper, our bags incorporate a conventional 2 to 4-layer composite structure. The material boasts excellent toughness and high tensile strength, making it resistant to tearing and impact. This durability ensures that the bags withstand long-distance transportation and multi-layer stacking without breaking or bursting, effectively reducing material loss.
The inner layer is equipped with a PE film that blocks moisture and dust, preventing product clumping and leakage of fine powders. Additionally, reinforced seams enhance the bag's sealing performance, making it ideal for packaging delicate powdered materials while maintaining product integrity.
Featuring a box-shaped 3D bottom design, the bag maintains a firm and upright posture after filling. This ensures stable stacking and palletizing without slanting, maximizing warehouse space utilization and facilitating easier storage management and container transportation.
The primary material is kraft paper, which is environmentally friendly, odorless, and recyclable. Our packaging complies with domestic environmental standards as well as export packaging regulations across various industries, promoting sustainable practices.
The flat surface of the bag supports multi-color printing including logos, company names, and product information. The printing is durable and resistant to fading, combining functional packaging with impactful brand display.
