HOWIE Co-Extrusion Film Blowing Machine

Advanced Multilayer Film Extrusion Solutions

HOWIE designs and manufactures high-performance Co-Extrusion Film Blowing Machines for global plastic film manufacturers, packaging producers, and industrial converters.

Our multilayer extrusion lines produce films with superior mechanical strength, barrier protection, and sealing performance. Featuring flexible configurations from 3-layer, 5-layer, to 7-layer systems, we deliver tailored production solutions for food packaging, medical films, agricultural sheeting, and industrial applications.

Complete Multilayer Film Solutions

Modern packaging demands multi-functional performance that single-layer materials cannot achieve. Our co-extrusion systems combine multiple extruders so each layer executes a specific function:

Outer Layers

Printability, slip properties, and mechanical strength.

Middle Layers

High-barrier protection against oxygen, moisture, and aroma transmission.

Inner Layers

Reliable heat-sealing, hot-tack strength, and food-contact safety.

Three To Seven Layer Blown Film Extrusion

Core Technical Advantages

Precise Thickness Control
Optimized manifolds and dynamic gauging maintain thickness variation within <±5%, reducing polymer waste and improving film consistency.

High Output Efficiency
Engineered for continuous industrial operation with efficient cooling loops and automated control architectures to maximize production uptime.

Energy-Optimized Architecture
Integrated heating controls, high-efficiency AC motors, and advanced screw designs lower specific energy consumption .

Flexible Material Compatibility
Supports LDPE, LLDPE, HDPE, EVA, PA, EVOH, and biodegradable resins such as PLA.

Advanced Machine Configuration

Extrusion & Die Head

High-precision extruders deliver stable plasticizing and uniform melt pressure, paired with multi-manifold die heads for accurate layer distribution.

Cooling & Gauge Control

Dual-lip air rings and internal bubble cooling (IBC) ensure rapid bubble stabilization and transparency, complemented by non-contact automatic thickness gauges.

Winding Systems

Back-to-back automatic turret winders ensure smooth roll transitions, optimal roll geometry, and minimal scrap.

Customized Engineering Solutions

Every plant has unique specifications. HOWIE provides bespoke engineering tailored to your operational parameters:

Film Structure Design

Targeted resin combinations for specific barrier or mechanical requirements.

Machine Configuration

Custom extruder sizing (L/D ratios), die diameters (100 mm to 1200 mm+), and automation tiers.

Turnkey Integration

Complete line engineering from resin feeding and extrusion to gauging, winding, and scrap recycling.

Global Quality Assurance & Support

Rigorous Testing
Every machine undergoes component inspection, dynamic balancing, full electrical integration testing, and a raw material trial run prior to factory dispatch.

After-Sales Service
Comprehensive support including installation supervision, remote digital commissioning, hands-on operator training, preventative maintenance, and fast-dispatch spare parts.

FAQ

Q: What is a Co-Extrusion Film Blowing Machine?

A: An industrial system using multiple extruders feeding into a single multi-manifold die to produce multi-layered plastic films combining different polymers for specific barrier and strength properties.

Q: What is the difference between 3-layer, 5-layer, and 7-layer lines?

A: The main difference is functional layer distribution. More layers allow processors to sandwich expensive barrier resins (like EVOH or PA) between structural polyolefins to optimize cost and performance.

Q: What raw materials can be processed?

A: Standard polyolefins (PE, PP), engineering plastics (PA, EVOH, EVA), and eco-friendly biodegradable compounds (PLA).

Q: Can HOWIE customize machines for unique specifications?

A: Yes. We provide bespoke engineering tailored to your exact output requirements, film widths, and factory floor layouts.

Q: How do you ensure long-term machine reliability?

A: We use top-tier electrical components, precision-machined alloy steel screws/barrels, and strict ISO-compliant quality checkpoints during manufacturing.

Q: What support is provided after purchase?

A: End-to-end support including layout drawings, on-site/remote installation, comprehensive staff training, and lifelong technical assistance.
