GL Transparent High Barrier FilmDiscover the advantages of our technology
GL FILM is the core of TOPPAN's GL BARRIER product family — a range of transparent high-barrier films developed using proprietary coating and vapor deposition technologies.
It protects packaged contents from oxygen, moisture and dehydration, helping maintain product quality and extend shelf life while keeping the package transparent.
For suitable applications, GL FILM can provide an alternative to aluminum-based barrier structures. Its transparency allows contents to remain visible, while selected film structures also support microwave heating and metal detection.
TOPPAN continues to develop GL BARRIER solutions that combine high barrier performance with packaging structures designed to support improved recyclability and mono-material approaches.

Medical and PharmaceuticalFor sensitive and sterile products
Medical and pharmaceutical products often require particularly high barrier performance to maintain product integrity and quality. Transparent GL FILM allows contents to be inspected without opening the package.
Selected GL FILM grades are also designed to withstand demanding sterilization conditions, including autoclave processing, while maintaining high barrier performance.
Personal Care and ToiletriesFor beauty & hygiene
The film helps protect and preserve products like cosmetics, shampoos, and detergents by preventing moisture loss, oxygen exposure, and the escape of fragrances.
Health & BeautyFor protection and product presentation
GL BARRIER Film helps protect cosmetics, personal care and hygiene products against moisture loss, oxygen exposure and loss of fragrance.
For products where appearance matters, transparency combines product protection with clear presentation, allowing consumers to see the contents while the barrier film helps preserve product quality.
Electronics. For sensitive high-tech components
GL FILM is used in packaging and technical applications where electronic components require protection during transportation and storage.
Transparent vapor-deposition films can help protect components from oxygen, moisture, particles and contaminants, chemicals and static electricity. GL FILM is also used in applications ranging from digital displays to solar components.
