Feature

HOWIE Three-Layer Co-Extrusion Film Blowing Machine

High-Performance 3-Layer Film Extrusion Solution for Flexible Packaging, Agricultural Films, and Industrial Applications

HOWIE manufactures advanced Three-Layer Co-Extrusion Film Blowing Machines engineered to produce high-strength PE films with uniform thickness and optimized material costs. Backed by 15+ years of manufacturing expertise, CE compliance, and global technical support, our systems help international manufacturers maximize production efficiency and ROI.

Overview & Layer Functionality

A Three-Layer Co-Extrusion Film Blowing Machine merges three distinct polymer streams through independent extrusion systems and a precision ABC die head into a single film structure. This technology allows independent functionalization of each layer:

Outer Layer

Engineered for printability, gloss, and surface properties.

Middle Layer

Optimized for cost reduction, enabling the safe integration of recycled PE or cost-effective polymers.

Inner Layer

Designed to enhance heat-sealing, flexibility, and barrier properties.

Core Advantages & Architecture

Lower Material Costs
Restricts expensive virgin resin to surface layers while safely embedding recycled PE or functional fillers in the middle layer.

Superior Mechanical Performance
Delivers higher tensile strength, puncture resistance, environmental barrier properties, and sealing performance compared to single-layer films.

Production Flexibility
Adapts to variable film widths, thicknesses, layer ratios, and output targets on a single production line.

Precision ABC Die Head & Extrusion
Ensures stable layer distribution, tight thickness tolerances, and smooth surface finishes with adjustable layer-thickness ratios via optimized single-screw designs and advanced thermal control.

Target Applications

Flexible Packaging

Food pouches, shopping bags, courier bags, and industrial liners.

Agriculture

Greenhouse films, mulch films, silage bags, and crop protection sheets.

Industry

Surface protection films, shrink films, construction membranes, and heavy-duty bags.
