Core Technology Breakdown
Dual Technologies for Versatile Needs
Gate Size Press
Working Principle
Dual-roll immersion coating forms a stable starch film through metering roll gaps, achieving double-sided sizing via submerged nip penetration.
Key Parameters
• Speed range: 80-400m/min
• Starch application: 1-8g/m² (single side)
• Starch solids: 8-14%
Applications
• Cultural paper surface strengthening (70-120g/m²)
• Corrugated medium water resistance (80-160g/m²)
Film Transfer Size Press
Working Principle
Metering rod precisely forms a starch film, transferred to the web via contact roll, with closed-loop residual starch recovery.
Key Parameters
• Speed range: 300-1200m/min
• Application accuracy: ±0.3g/m²
• Starch solids: 12-18%
Applications
• Liquid packaging board (200-400g/m²)
• High-strength kraft paper (100-180g/m²)
