Applications:
Efficiently produces high-strength, multi-layer composite valve sacks suitable for granular or powdered chemical raw materials (e.g., fertilizers, resins, paint powders).
Dimensions:
Width: 350–680 mm; Length: 500–1350 mm; Tolerance ≤ ±3 mm. Customizable as square-bottom or valve sacks.
Speed:
Tube forming speed up to 200–250 tubes/minute.
Sealing Options:
Bottom pasting machine offers multiple sealing solutions including ultrasonic valve sealing, hot-melt valve sealing, and laminated inner valves—dual-seal design prevents leakage and meets stringent hazardous material packaging standards.
Layers:
Supports 2–4 layers of kraft paper + 1 layer of PE inner film, ensuring excellent moisture resistance, leak-proof performance, and tear strength.
Equipment Advantages:
1.Servo motor-driven system ensures precise square bag shape and uniform sealing pressure, preventing powder leakage.
2.Material-contact parts are made of stainless steel—corrosion-resistant and compliant with hygiene standards.
