Introduction to PET Sheet Production Line

The PET Sheet Production Line is a state-of-the-art system engineered for producing high-quality PET (Polyethylene Terephthalate) sheets used in a variety of industries such as food packaging, electronics, construction, and thermoforming.
This line ensures excellent transparency, mechanical strength, and surface finish, meeting the demands of modern industrial and packaging markets.

Polytechme’s PET sheet lines are built with energy-efficient extrusion systems, precise temperature control, and advanced automation, ensuring stable performance and consistent product quality.

Working Principle

The PET production process begins by feeding raw PET granules or flakes into a twin-screw extruder, where the material is melted, filtered, and homogenized.
The molten polymer is then extruded through a flat die to form a uniform sheet.
Afterward, the sheet passes through three-roll calendering, cooling, and winding systems, resulting in a smooth, clear, and stable PET sheet suitable for further processing or direct use.

Key Features

1. High Transparency and Gloss – Produces crystal-clear sheets with excellent optical properties.
2. Energy Efficiency – Advanced screw design and optimized heating reduce power consumption.
3. Stable Thickness Control – Automatic thickness measurement and correction ensure uniform sheets.
4. Recycling Capability – Can process both virgin and recycled PET materials.
5. Fully Automated Control System – PLC and touchscreen interface for precise and user-friendly operation.
6. Low Maintenance – Built for durability and easy cleaning with corrosion-resistant components.
