■ T die-casting film machine equipment introduction

1. Equipment overview

A casting machine is a device that produces non-stretched PET film (non-oriented film) by heating and melting PET resin, extruding it into a slit shape
through a T-die, and then rapidly cooling and molding it on a cooling drum.The resulting film has uniform thickness, high transparency, and dimensional
stability, making it suitable for a variety of applications.

2. Main Features

・High optical properties and smoothness: High-precision T-die design and cooling drum control achieve a surface finish with excellent transparency and smoothness.
・Capable of producing double-sided heat-sealable PET film: The unstretched PET film produced by our casting machines can be made heat-sealable on
　both sides. This increases the flexibility of packaging material design, contributes to stabilizing seal strength, streamlining the sealing process, and improving
　package reliability.
・Stable film thickness control: Thickness temperature zone control and edge pinch technology minimize thickness variation across the width
・Compatible with a variety of resins: Compatible with recycled PET , PET with additives, etc., contributing to the production of
　environmentally friendly products.

3. Environmentally friendly initiatives

・Compatible with recycled PET : Compatible with film manufacturing using recycled PET, contributing to reducing environmental impact and
　building a recycling-oriented society.
・Equipped with a scrap material return system: The return system pelletizes scrap materials generated during manufacturing on-site and re-introduces
　them, minimizing waste.
