The VihoX 110+65 PP/PS Co-extrusion Sheet Line is engineered for converters seeking to produce high-value multi-layer barrier sheets, dual-color beverage cup stock, and cost-optimized packaging with recycled core layers (ABA structure). Combining a Φ110 mm primary extruder (approx. 55 kW motor) with a Φ65 mm auxiliary co-extruder, both featuring a 33:1 L/D ratio, this co-extrusion line delivers a steady output of approx. 200 kg/h.
Equipped with a specialized 2–3 layer adjustable co-extrusion feedblock, a 150CC precision melt metering pump, and a 1000 mm coat-hanger die, the system forms finished sheet widths from 500 to 880 mm. Sheet thickness ranges cover 0.3 mm to 2.0 mm for PP and 0.2 mm to 2.0 mm for PS. Web calibration and cooling are managed by a specialized three-roll stack (Φ350×1000×1 + Φ450×1000×2) driven by independent electric motors, achieving line speeds between 15 and 30 m/min with exceptional layer distribution accuracy.

Packaging converters face intense margin pressure from raw virgin resin prices while complying with strict food contact safety regulations. The VihoX 110+65 line provides the ultimate technical answer: its ABA co-extrusion feedblock allows the main 110 extruder to run up to 70% low-cost crushed skeleton regrind or recycled pellet material in the center core layer (B), while the secondary 65 extruder covers both exterior surfaces with virgin food-grade polymer (A). The resulting sheet provides 100% food-grade contact surface appearance, perfect sealability, and dramatic raw material cost savings.
Co-extruding multiple polymer streams with divergent viscosities requires precise pressure balance before the streams converge inside the feedblock. The VihoX 110+65 incorporates a 150CC precision melt pump that eliminates volumetric surging in the primary flow channel. Downstream, an asymmetrical three-roller calender stack (Φ350 mm top roll paired with two Φ450 mm high-capacity rolls) ensures prolonged web contact on the high-cooling side, preventing sheet curling and delamination.
This dual-extrusion line serves diverse packaging applications:
The co-extrusion feedblock features adjustable internal selector vanes allowing skin-to-core layer ratios from 10/80/10% up to 25/50/25% (or 20/80% for two-layer AB sheet).
Yes. By feeding different color masterbatches into the main 110 extruder and auxiliary 65 extruder, the line produces vibrant dual-color (AB) sheet rolls with sharp, distinct layer boundaries.
While total installed power is approx. 150 kW to accommodate cold startup heating, actual running power consumption stabilizes at approx. 80 kW during standard steady-state production.
Because both streams use the same base polymer matrix (e.g. PP virgin + PP regrind), thermal diffusion inside the feedblock creates permanent molecular weld with zero delamination risk.
Both the main 110 and auxiliary 65 extruders are equipped with continuous hydraulic slide-plate screen changers driven by a shared hydraulic power station.
Each calender roll is driven by an independent electric gear motor controlled by dedicated inverters, enabling fine micro-speed adjustment across the cooling web.
The physical machine footprint measures approx. 12 × 2.0 × 2.5 m. A ceiling height of ≥ 3.5 m is recommended for overhead crane roll removal and hopper loader clearance.
