The 4 layer 4 fold coextrusion die head is a robust and efficient solution for modern blow molding applications requiring advanced material layering and high-volume output. Designed for industrial manufacturers who demand superior quality, this extrusion head supports the combination of barrier and adhesive layers, along with optional features like view stripe capability.
Whether you’re producing technical containers, chemical packaging, or multilayer bottles for consumer use, this system offers precision, flexibility, and long-term reliability.
Advanced 4 Layer Technology for Functional Packaging
Designed for Barrier, Adhesive, and View Stripe Coextrusion
The 4 layer 4 fold die head integrates multiple extruders to process a wide range of materials. It includes:
-
PA Extruder – For barrier layer applications using Polyamide (PA), providing excellent oxygen resistance.
-
Adhesive Extruder – To bond dissimilar materials such as polyolefins and barrier resins, ensuring structural integrity.
-
View Stripe Extruder – Adds a transparent line to the container, enabling users to see the fill level at a glance.
-
Main Extruder – Handles the primary polymer layers such as HDPE or PP.
Together, these components deliver a container structure that is not only strong but functional and customer-friendly.
4 Fold Die Head for Multi-Cavity High Output
Efficient Production with Four Parallel Flows
The 4 layer 4 fold configuration enables four cavities to run simultaneously, drastically increasing output without sacrificing quality. The balanced melt flow to each fold ensures that all products maintain consistent wall thickness and layer distribution.
Benefits of 4-fold design:
-
Higher production efficiency
-
Uniform product performance across all molds
-
Reduced cycle time for large batch manufacturing
-
Excellent layer adhesion and repeatability
This system is ideal for facilities needing medium to high-volume production with strict quality control.
Integrated Electric Water Temperature Control (WTC)
Precision Thermal Management
The Electric WTC system offers intelligent and adjustable temperature control across all zones of the die head. This ensures optimal viscosity and melt flow for each layer, reducing waste and improving product consistency.
Key advantages:
-
Fast warm-up times
-
Accurate control over thermal profiles
-
Enhanced safety and energy efficiency
-
Minimized start-up scrap
With precise thermal stability, your 4 layer 4 fold extrusion process becomes more consistent and cost-effective.
Material Flexibility and Application Range
Compatible with Various Resins
The die head system is engineered to process multiple resins, including:
-
HDPE – For durable outer and inner layers
-
PA (Polyamide) – For high-barrier middle layers
-
EVOH – As an alternative for gas barrier applications
-
Adhesive Resins – For bonding between incompatible layers
-
Transparent Polymers – For view stripe applications
These combinations allow the 4 layer 4 fold head to be used in a wide range of industries, such as:
-
Automotive fluid packaging
