Aluminum-Coated PET Release Film: Properties, Applications, and Industry Standards
Introduction
Aluminum-coated PET (Polyethylene Terephthalate) release film is a high-performance material widely used in industries requiring precision, durability, and thermal stability. This film consists of a PET base layer coated with a thin aluminum layer, offering excellent barrier properties, heat resistance, and dimensional stability. Its applications span across electronics, automotive, aerospace, and packaging industries. This article explores the manufacturing process, key properties, applications, and industry standards for aluminum-coated PET release film.
1. Structure and Manufacturing Process
1.1 Base Material: PET Film
PET film is chosen for its:
High tensile strength
Excellent chemical resistance
Thermal stability (up to 150°C)
Low moisture absorption
1.2 Aluminum Coating Process
The aluminum layer is applied using:
Vacuum Metallization: A thin, uniform aluminum layer is d…
