PE Multilayer Co-Extrusion Barrier Sheet Production Line

The PE multilayer co-extrusion barrier sheet production line uses advanced co-extrusion technology to produce high-performance polyethylene sheets.

This line combines multiple materials, including barrier resins, into one sheet.
It improves barrier performance while keeping the flexibility and strength of PE.
At the same time, it helps control production costs.

The sheets are ideal for packaging that needs protection from moisture, oxygen, and light, such as food, pharmaceutical, and other sensitive products.

Working Principle

The production line uses multi-layer co-extrusion technology.

  • Each extruder melts and processes one material layer.
  • All layers are combined in a special die to form a multi-layer sheet.
  • Outer PE layers provide strength and flexibility
  • Inner barrier layers (such as EVOH or nylon) block moisture, oxygen, and UV light
  • After extrusion, the sheet is quickly cooled, then pulled and cut to the required size.

Main Technical Features

Multi-Layer Co-Extrusion Technology

The line can combine different materials with different functions.
Barrier materials like EVOH or nylon can be added to the core layer to improve protection.

High-Precision Die System

The die ensures:

Even material distribution

Uniform sheet thickness

Smooth surface quality

This helps improve the mechanical performance of the final sheet.

Advanced Barrier Materials

Barrier layers provide strong resistance to:

Oxygen

Moisture

Light

This helps extend the shelf life of packaged products.

Efficient Cooling and Haul-Off System

The cooling system solidifies the sheet quickly and smoothly.
The haul-off system keeps a stable tension and prevents deformation or breakage.

Automatic Control System

The line is equipped with a PLC control system.

Easy operation

Real-time monitoring

Stable and consistent production

This reduces human error and improves efficiency.

Flexible Sheet Specifications

Sheet thickness, width, and layer structure can be adjusted.
DWELL can customize the configuration based on customer needs.

Material Advantages

Excellent Barrier Performance

The multi-layer structure protects products from moisture, oxygen, and UV light.
