As global packaging demands continue to rise, brands are seeking materials that deliver high barrier performance without sacrificing transparency or sustainability. Transparent ALOx (Aluminum Oxide) PET film has emerged as a next-generation solution, combining advanced barrier protection with premium visual appeal.

ALOx PET film features a nano-scale aluminum oxide coating deposited on a PET substrate. This transparent coating provides excellent oxygen and moisture barrier properties, helping extend shelf life while allowing full product visibility. Compared with traditional metallized films, ALOx PET maintains clarity, making it ideal for brands that value both performance and aesthetics.

Beyond its barrier advantages, ALOx PET film offers strong chemical stability, heat resistance, and excellent mechanical strength, ensuring reliable performance during lamination, printing, and packaging processes. It is widely used in food, beverage, pharmaceutical, and high-end consumer packaging, where freshness protection and brand presentation are equally critical.

From a sustainability perspective, transparent ALOx PET film supports material reduction and recyclability initiatives by replacing thicker or multi-layer structures while maintaining high barrier efficiency. This makes it a smart choice for companies aiming to meet evolving environmental regulations and sustainability goals.

At Cailong Coating, we continue to invest in advanced coating technology and precision testing to deliver consistent, high-performance ALOx PET films tailored to global market needs. Innovation, reliability, and quality remain at the core of everything we produce.
