In blown film manufacturing, gauge uniformity is the single most critical factor determining bag strength, sealing reliability, and raw material efficiency.
Automatic air ring and bubble control
Modern extrusion lines utilize computerized air rings that adjust localized cooling around the extruded polymer bubble. This real-time thermal compensation eliminates thin spots and ensures consistent gauge tolerance across the entire roll width.
Benefits of 3-layer co-extrusion
Co-extrusion allows us to combine virgin barrier resins on outer layers with specialized core polymers, delivering unmatched puncture resistance at optimized thicknesses.
