Key Features
Multi-layer Durable Structure for Load Bearing and Impact Resistance
Made from high-quality colored kraft paper (80-120 GSM) laminated with 2-4 layers of water-based environmentally friendly adhesive. Tensile strength: ≥4.5 kN/m (machine direction), ≥3.5 kN/m (cross direction). Bursting strength: ≥1400 kPa. Withstands 2-meter drops without damage.
Customizable Color Printing for Enhanced Brand Recognition
Supports spot color and four-color offset printing with vivid colors, strong adhesion, and excellent abrasion resistance. High-definition full-color printing for logos and product information display.
Valve Seal Design for Dust-free and Efficient Filling
Options include internal or external valves with ultrasonic heat sealing technology. Valve automatically closes during filling to prevent powder leakage and dust dispersion. Valve dimensions precise within ±5mm for fast filling speeds and excellent sealing performance.
Moisture and Dust Barrier to Ensure Quality and Freshness
Optional PE liner provides moisture-proof and leak-resistant features, effectively blocking water vapor and dust to extend material shelf life. All-paper structure is odorless and pollution-free.
Eco-friendly, Biodegradable, and Cost-Effective Compliance
Made from renewable plant fibers, kraft paper is recyclable and naturally biodegradable. Meets "plastic ban" regulations and green supply chain requirements. Reduces environmental costs compared to plastic woven bags.
Space-saving Stackability and Efficient Logistics
Square bottom three-dimensional structure for neat stacking and strong stability. Prevents sliding and collapse, improving warehouse space utilization. Lightweight yet tough design uses less material while handling same loads.
