Moderate Moisture Resistance Kraft Multiwall Bags with Optional PE Film Liner
Product Overview
Multi-layer kraft paper valve bags are premium automated packaging products specifically designed for industrial powders and granular materials. These bags feature a composite structure made of three layers of paper combined with one layer of film, ensuring durability and reliability.
Equipped with a square valve and three-dimensional flat bottom design, these bags are perfectly compatible with high-speed automatic filling machines. They offer excellent strength, superior sealing performance, dust-free operation without powder leakage, and neat stacking arrangement.
Widely used in industries such as metallurgy alloys, refractory materials, chemical powders, and construction additives, these valve bags are suitable for packaging materials weighing between 25 to 50 kilograms. They serve as a standardized industrial packaging solution replacing conventional woven bags.
The product supports customization in terms of the number of layers, materials, and specifications, allowing for personalized packaging solutions to meet various industrial requirements.
Key Features
Dust-Free Filling: Specialized valve design ensures rapid air discharge without powder spillage, eliminating workshop dust issues
High Durability: Multi-layer kraft paper composite structure with thickened inner liner provides excellent tensile strength, puncture resistance, and drop resistance
Moisture-Proof Protection: Internal waterproof and barrier liner prevents deterioration and caking of easily oxidized or moisture-absorbing materials
Regular Shape: Glued bottom square-bottom process maintains square, upright shape for neat stacking and maximum storage utilization
Automation Compatible: Works with fully automatic filling systems, reducing labor costs and improving packaging efficiency
Environmentally Friendly: Made from degradable and recyclable high-strength kraft paper material without harmful additives
