Need a quick recommendation? If you produce barrier packaging film or need different polymers in each layer for specialized performance, the MYT-2200 ABC 3-layer co-extrusion line gives you independent control over all three layers. Get a free configuration proposal.
The MYT-2200 is engineered for manufacturers who need maximum formulation flexibility in a 3-layer film structure. Unlike ABA machines — where both skin layers share the same material — the ABC configuration runs three independently controlled extruders, each capable of processing a different polymer. This means you can build films with a specific function per layer: a high-gloss printable skin, an oxygen-barrier core, and a low-temperature seal layer, all in one pass.
Products commonly produced on the MYT-2200:
High-barrier food packaging film: PE/PA/PE or PE/EVOH/PE structures for vacuum packs, modified atmosphere packaging, and extended shelf-life products. The barrier resin in the core layer reduces oxygen transmission by a factor of 10-100x compared to monolayer PE film.
Lamination base film: Precision-gauge co-extruded film for flexible packaging laminates in snack food, personal care, and pharmaceutical applications. ABC layer control enables one-side-treated structures where the print surface and seal surface have different COF and surface energy requirements.
Heavy-duty shrink film: Multi-layer collation shrink with optimized puncture resistance, used in logistics, beverage bundling, and construction material wrapping.
Liquid packaging film: High-strength multi-layer structures for bag-in-box, liquid detergent refill packs, and edible oil packaging where seal integrity and drop-test performance are critical.
Talk to an engineer about your film structure: The layer configuration that works for a snack food laminate may not work for a liquid detergent pouch. Send us your target film specs and our application team will recommend the optimal extruder and die setup.
Each of the three extruders runs its own temperature profile, screw speed, and material feed. This means you can process a heat-sensitive barrier resin like EVOH in the core at 210-230°C while running metallocene PE at 180-200°C in the skin layers — processing each polymer at its optimal window, not a compromise temperature that half-degrades one material to accommodate the other. The result is better barrier performance from the EVOH and better optical clarity from the PE skins.
The B layer can run up to 30% recycled PE or lower-cost filler-grade resin without affecting film surface appearance or mechanical properties. Since the A and C skin layers encapsulate the core, the film looks and performs like all-virgin material. A factory producing 500 tons of film annually, running 25% recycled content in the B layer, saves approximately $100,000-150,000 per year in raw material cost at current recycled PE pricing.
Spiral mandrel die design with chrome-plated flow surfaces ensures uniform melt distribution across the full web width. Combined with a dual-lip air ring and optional IBC (Internal Bubble Cooling), the MYT-2200 maintains stable bubble formation at output rates competitive with international lines in the same class. The oscillating haul-off distributes gauge bands evenly, keeping thickness variation within ±5% across the roll — the tolerance that automated packaging lines require.
Independent extruder purging means you can change one layer's material without disturbing the other two. Switching the core layer from recycled PE to HDPE for a stiffness run takes 30-40 minutes of purging on one extruder — the skins keep running. On a single-layer or ABA machine, a material change means stopping and purging the entire system.
Material Feeding: Three independent hoppers feed polymer pellets into extruders A, B, and C. Gravimetric dosing units (optional) control blend ratios of virgin resin, recycled material, and masterbatch to ±0.5% accuracy per layer.
Melting and Plastication: Each single-screw extruder — with L/D ratios configured to the target polymer — melts and homogenizes the material through controlled barrel heating and screw shear. Independent PID temperature control per zone maintains each polymer at its optimal processing window.
3-Layer Co-Extrusion: The three melt streams converge inside the spiral mandrel die head. The ABC mandrel design distributes each layer into a concentric ring while preventing interfacial flow instability between layers of differing viscosity — a key quality factor that separates well-designed co-extrusion dies from poorly designed ones.
Bubble Formation: Compressed air inflates the multi-layer melt into a bubble at the desired blow-up ratio. The dual-lip air ring delivers controlled external cooling. With IBC engaged, chilled air circulates inside the bubble for simultaneous internal cooling — increasing solidification rate and output by 15-25%.
Stabilization and Collapsing: A height-adjustable collapsing frame and stabilizer basket guide the bubble into the nip rollers. The frame accommodates different BURs without hardware changes.
Winding: The film passes through the oscillating haul-off and is wound by a surface or center winder — single or dual-turret depending on output — into finished rolls ready for gravure printing, lamination, or bag making.
Each MYT-2200 line is built to order. Select the systems that match your production requirements:
Auto Air Ring: Motorized lip adjustment driven by real-time gauge feedback. Compensates for ambient temperature drift across shifts. For 24/7 lines, this typically pays for itself through reduced scrap within 12-18 months.
IBC (Internal Bubble Cooling): Adds 15-25% to output by cooling from inside the bubble. Also stabilizes the bubble for thin-gauge and HDPE films where melt strength is lower.
Corona Treater: Increases film surface energy to 38-42 dynes for ink adhesion. Standard for producers supplying the printing and converting industry.
EPC (Edge Position Control): Ultrasonic or optical sensor maintains web alignment during winding. Prevents telescoping on thin films and reduces edge trim waste.
Gravimetric Dosing: Per-extruder loss-in-weight dosing for virgin resin, recycled material, and masterbatch. Eliminates manual pre-blending and ensures batch-to-batch formulation consistency.
Automatic Vacuum Loader: Pneumatic pellet conveying from storage to extruder hoppers. Reduces manual handling, contamination risk, and operator workload on multi-machine shifts.
SCADA Monitoring: Real-time data logging of temperatures, pressures, screw speeds, output, and layer ratios. Enables process traceability and recipe optimization over time.
20+ years focused on blown film: We do not make injection molding machines, we do not make pipe extruders. Our engineering team designs screws, dies, and complete film lines — that is the entire business. Every machine ships from our factory in Jiangyin, Jiangsu, a recognized center of plastics machinery manufacturing in China.
CE certified: All MINGYANG blown film machines carry CE certification. Full documentation provided for EU customs clearance and regulatory compliance.
Machines running in 60+ countries: Our equipment operates in packaging factories across Southeast Asia, the Middle East, Africa, South America, and Eastern Europe. We handle container loading, sea freight documentation, and destination port coordination.
Customer example — Indonesia: A Surabaya-based packaging manufacturer replaced two aging mono-layer lines with one MYT-2200 ABC machine in 2024. Running a PE/PA/PE barrier film structure for food packaging, their film scrap rate dropped from 6.5% to under 3% within the first quarter. The independent layer temperature control on the ABC machine eliminated the barrier-layer degradation issue they had been fighting on their previous equipment.
Engineer support before and after purchase: Pre-sales: we recommend extruder sizing, screw design, and die configuration based on your specific film product — not a catalog standard. Post-installation: video call support, remote diagnostics, and optional on-site service engineer dispatch.
Spare parts dispatched same-week: Common components — heater bands, thermocouples, SSRs, seals, bearings — stocked for immediate air-freight dispatch. Long-lead custom parts can be pre-ordered with the machine.
For standard LDPE/LLDPE film at 1000mm lay-flat width and 50-micron thickness, output ranges from 100 to 180 kg/h depending on extruder configuration. Output varies with film thickness, material type, and blow-up ratio. Contact our team with your target film specs for a detailed estimate based on your specific formulation.
Layer A (outer skin): LDPE, LLDPE, metallocene PE for optical and surface properties. Layer B (core): LDPE, HDPE, recycled PE, PA (nylon), EVOH, or tie resin for barrier or stiffness. Layer C (inner skin): LDPE, LLDPE, metallocene PE optimized for heat-seal performance. With appropriate screw configuration, PLA and PBAT biodegradable compounds can also be processed.
In an ABA machine, the two outer skin layers (A) share one extruder and must use the same material. This works well for recycled-content packaging film — virgin PE skins, recycled PE core. In the ABC configuration, all three layers are independent — you can run PE in layer A, PA or EVOH barrier resin in layer B, and a heat-seal formulation in layer C. ABC costs more but provides maximum formulation flexibility for high-performance packaging applications. If your primary need is recycled content savings, an ABA blown film machine is usually the more cost-effective choice.
Yes, with the appropriate screw and die configuration. HDPE requires a longer L/D screw (30:1 to 34:1), lower compression ratio (2:1 to 3:1), and a wider die gap (1.8-2.5mm). Specify HDPE compatibility at quotation stage so we configure the extruder and die correctly — retrofitting after delivery is costly.
Standard configuration: 45-60 days from order confirmation and deposit. Custom screw designs or non-standard die diameters: 75-90 days. Sea freight transit from China adds 20-35 days depending on destination, plus 5-10 days for customs clearance and inland transport.
12 months from commissioning or 18 months from shipment, whichever occurs first. Covers manufacturing defects in materials and workmanship. Wear parts — heater bands, seals, belts — are consumables and excluded from standard warranty.
Disassembled into major modules — extruders, die head, tower, haul-off, winder — and packed in moisture-protected wooden crates for containerized ocean freight. All electrical panels are vacuum-sealed with desiccant. A typical MYT-2200 fits into one 40-foot high-cube container. Large configurations may require two containers.
Yes. A MINGYANG service engineer travels to your factory for installation supervision, commissioning, production trials, and operator training. Typical on-site duration: 7-14 days. Training covers start-up, recipe setup, routine maintenance, and basic troubleshooting.
We recommend a starter kit: heater bands, thermocouples, solid-state relays, air ring seals, winding shaft bearings, and common electrical components. A recommended parts list with part numbers is provided with your quotation. Parts ship by air courier for urgent needs or by sea for scheduled maintenance stock.
Within the same polymer family (e.g., switching LDPE grades): 20-40 minutes per extruder. The independent extruder design means you purge one layer at a time — the other two keep running. For incompatible material changes, thorough purging with an intermediate material is recommended.
