Overview
The Eurotech B-30 Laboratory Multi-Layer Co-Extrusion Blown Film Extrusion Line is a precision-engineered pilot-scale system designed for R&D laboratories, polymer formulation centers, and quality assurance departments in the plastics and packaging industries. It operates on the fundamental principle of tubular blown film extrusion—where molten polymer is extruded through an annular die, inflated by internal air pressure into a bubble, cooled via external air rings, and collapsed into a double-layered flat film. The B-30 supports true co-extrusion architecture with up to three independently controlled extruders (configurable per user requirement), enabling the simultaneous processing of dissimilar polymers—such as PE/PA/EVOH or PP/PS/PE—to produce multilayer structures with defined barrier, sealant, or mechanical performance characteristics. Its modular design facilitates rapid reconfiguration for material screening, process parameter optimization (e.g., blow-up ratio, frost line height, haul-off speed), and ASTM D2614-compliant film property validation.
Key Features
- Modular co-extrusion platform with up to three synchronized single-screw extruders (20–70 mm screw diameters), each equipped with independent PID-controlled barrel heating zones and calibrated melt pressure transducers
- High-precision annular die assembly with adjustable gap (0.5–2.0 mm), interchangeable mandrel inserts, and uniform circumferential temperature distribution (±1.5°C)
- Programmable air ring system with dual-zone airflow control (inner/outer) to stabilize bubble geometry and optimize crystallinity profile across film thickness
- Motorized collapsing frame with variable nip roll pressure and differential winding tension control (0.1–5.0 N) for consistent layflat width and edge trim management
- Integrated real-time monitoring of critical process variables: melt temperature (±0.5°C), screw RPM (0.1–120 rpm), motor load (% torque), air pressure (0–1.2 bar), and line speed (0.1–20 m/min)
- Stainless steel construction (AISI 304) with CE-compliant safety interlocks, emergency stop circuitry, and IP54-rated electrical enclosures
Sample Compatibility & Compliance
The B-30 accommodates a broad spectrum of thermoplastic resins—including LDPE, LLDPE, HDPE, PP, PS, EVA, TPU, and functional masterbatches—without requiring hardware modification. Feed throat geometry and screw configuration (conveying, mixing, metering) are optimized for both virgin and recycled feedstocks. All wetted components comply with FDA 21 CFR §177.1520 for food-contact applications. System documentation supports GLP/GMP traceability: calibration certificates for all sensors (traceable to NIST standards), equipment qualification protocols (IQ/OQ), and raw material lot tracking integration. The line meets ISO 1133 (melt flow rate correlation), ASTM D882 (tensile properties), and ISO 527-3 (film elongation) test preparation requirements.
Software & Data Management
The B-30 is controlled via Eurotech’s proprietary WinFilm™ LabSuite v4.2 software, running on an embedded industrial PC with Windows 10 IoT Enterprise. The interface provides synchronized acquisition of 32+ analog/digital process channels at 10 Hz sampling rate, with timestamped data export in CSV, Excel, and HDF5 formats. Audit trails record all operator actions, setpoint changes, and alarm events—fully compliant with FDA 21 CFR Part 11 for electronic records and signatures. Batch reports include metadata (material lot ID, operator, ambient RH/temp), process trend plots (bubble stability index, thickness CV%), and auto-generated summary tables aligned with internal SOPs or customer-specific reporting templates.
Applications
- Development of high-barrier packaging films for pharmaceutical blister lidding and medical device pouches
- Optimization of seal initiation temperature (SIT) and hot-tack profiles in multilayer PE-based structures
- Evaluation of rheological compatibility between immiscible polymer pairs under shear and extensional flow conditions
- Accelerated aging studies of UV-stabilized agricultural mulch films under controlled extrusion-to-weathering workflows
- Validation of recycled content limits (e.g., post-consumer rLDPE) in food-grade film formulations per EU Regulation (EC) No 282/2008
- Training platform for technical personnel on blown film defect diagnostics (e.g., gauge banding, helix lines, bubble flutter)
FAQ
What is the minimum recommended sample quantity per formulation trial?
Typical trials require 1.5–2.0 kg of polymer per extruder to ensure thermal equilibrium and stable bubble formation; smaller batches (≥500 g) are feasible with pre-conditioned screws and shortened stabilization intervals.
Can the B-30 be integrated with inline thickness gauging systems?
Yes—the line includes standardized mounting flanges and analog I/O ports compatible with beta-backscatter (e.g., BetaScan Pro) and IR-based (e.g., InfraScan 3000) gauges; Eurotech provides OEM-level API documentation for third-party integration.
Is nitrogen purge capability available for oxygen-sensitive polymers?
An optional inert gas manifold kit (with mass flow controllers and die-integrated purge nozzles) is offered for processing PVOH, PA6, or metallized layers under <50 ppm O₂ environments.
Does Eurotech provide application support for new material development?
All B-30 deliveries include a 2-day on-site startup workshop and 12 months of remote technical consultation with Eurotech’s Application Engineering Team, including DOE-based protocol design and failure mode analysis.
