Overview
The Sumitomo Moden SU21 Blown Film Extrusion Line is an industrial-grade, water-cooled downward blown film system engineered for precision, stability, and regulatory compliance in high-value polymer processing—particularly for medical-grade films requiring strict thermal control, dimensional uniformity, and particulate-free output. Developed by Sumitomo Heavy Industries Moden Co., Ltd., the SU21 integrates a proprietary DELSER-series single-screw extruder with MBS (Multi-Barrier Screw) technology, enabling low-temperature, high-output extrusion while minimizing thermal degradation and melt homogeneity variation. The system operates on the fundamental principle of tubular bubble stabilization via controlled circumferential air flow, internal/external bubble cooling, and synchronized haul-off and winding dynamics. Its downward orientation—combined with integrated water-cooling channels in the die and mandrel—ensures rapid quenching of heat-sensitive resins such as polyethylene (PE), ethylene-vinyl acetate (EVA), and cyclic olefin copolymers (COC) used in sterile packaging and pharmaceutical barrier applications.
Key Features
- DELSER-series extruder with MBS screw geometry: Optimized for low shear heating, reduced pressure fluctuation (< ±1.5 bar), and elimination of unmelted resin carryover—critical for consistent melt temperature profiles (±0.5 °C) across production runs.
- AMF-type annular air ring with adjustable radial airflow distribution: Enables real-time thickness profile correction via automated zone-based air volume modulation; compatible with AHF-modified configurations for widths up to 2,200 mm.
- Integrated internal bubble cooling (IBC) and external air-ring cooling with cryogenic gas generation: Achieves bubble stabilization at line speeds exceeding 120 m/min under ISO 22087-compliant conditions.
- Top-mounted rotating winder with dancer-roll tension feedback and automatic edge-guidance: Ensures defect-free, low-wrinkle winding with radial runout < 0.15 mm and lay-flat width repeatability within ±0.3 mm.
- MACS (Moden Advanced Control System) PLC-based platform: Supports recipe management, batch logging, alarm history, and real-time PID loop monitoring per critical axis (extruder zone temp, air ring pressure, haul-off speed, winder torque).
Sample Compatibility & Compliance
The SU21 is validated for processing FDA-listed polymers including LDPE, LLDPE, mLLDPE, EVOH, and co-extruded multilayer structures (up to 5 layers). Its water-cooled die head and low-shear MBS screw meet ISO 1133 (melt flow rate testing prerequisites), ASTM D2673 (blown film tensile property standard), and JP/USP extractables profiling requirements for pharmaceutical packaging. All control logic and data storage comply with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) and support 21 CFR Part 11 audit trails when configured with user authentication and electronic signature modules.
Software & Data Management
The MACS interface provides a Windows-based HMI with dual-language (English/Japanese) support, OPC UA server integration, and CSV/Excel export for process parameter logs (extrusion rate, melt pressure, air ring differential pressure, bubble diameter, frost line height). Historical data is retained for ≥12 months with automatic backup to network drives or NAS. Optional GMP Mode enables electronic batch records (EBR), deviation tracking, and configurable SOP-triggered alerts—fully traceable to individual operator IDs and time-stamped actions.
Applications
Primary use cases include manufacturing of Class II medical device pouches (ISO 11607-1), IV bag laminates, diagnostic test strip substrates, and high-barrier food packaging films. Secondary applications encompass R&D-scale formulation validation, DOE-based process window mapping, and qualification of bioresorbable polymers (e.g., PLLA, PCL) where narrow thermal history windows dictate bubble stability.
FAQ
Is the SU21 suitable for cleanroom-integrated production lines?
Yes—the machine’s sealed gearmotor housings, stainless-steel frame construction (304/316 options), and HEPA-filtered air supply paths meet ISO 14644-1 Class 7 environmental requirements when installed with appropriate HVAC coordination.
Can the MACS system interface with MES or ERP platforms?
Yes—via native OPC UA, Modbus TCP, or optional Siemens S7-1500 gateway modules for bidirectional data exchange with SAP, Rockwell FactoryTalk, or custom MES environments.
What validation documentation is provided with the system?
Standard delivery includes FAT/SAT protocols, IQ/OQ templates aligned with ISO 9001:2015 and Annex 11, electrical schematics, mechanical drawings, and full MBS screw performance characterization reports.
Does Sumitomo offer on-site commissioning and operator training?
Yes—comprehensive startup services include mechanical alignment verification, thermal profiling, bubble stability optimization, and GMP-compliant SOP development workshops conducted by certified Sumitomo Field Engineers.
