Product Description
The kraft paper valve bag is a high-strength packaging container specially designed for industrial powders and granular materials. It is made from multiple layers of durable and flexible kraft paper combined with a polyethylene (PE) inner lining that prevents leakage. Equipped with an automatic filling valve structure, this bag has become the mainstream standardized packaging product in industries such as chemical, construction materials, and new materials.
This product supports fully automatic spiral filling and vacuum filling production lines. During the filling process, air is automatically expelled and the bag body is shaped and filled to capacity without the need for manual sealing. This significantly improves packaging efficiency while reducing damage rates and labor costs.
The kraft paper valve bag is widely suitable for packaging 20-25 kg industrial materials such as carbon black, cellulose, latex powder, tile adhesive, putty powder, dry mortar, and chemical powders. Customization options are available for the number of layers, specifications, printing, as well as anti-leakage and anti-static features.
Made from high-strength stretch kraft paper (80-100g/m²) with multi-layer composite structure offering excellent tensile strength and tear resistance.
Fully sealed PE inner liner created through heat-sealing technology prevents powder leakage and dust emission for ultra-fine powders.
Dedicated valve allows automatic air release during filling, keeping bags smooth and flat without ballooning.
Designed to resist moisture and weather conditions, preventing powder agglomeration and dampness in humid climates.
Valve seals automatically under material pressure, eliminating need for manual stitching or tape sealing.
Maintains neat, upright form for uniform stacking and enhanced warehouse storage utilization.
