Barrier Film

GL BARRIER

Barrier Film Performance Materials & Energy Medical & Pharma Goods Foods & Confectionery Toiletries Beverages Industrial Materials Earth-Friendly Materials

A transparent vapor-deposited barrier film that has a leading share of the global market and is used worldwide.

Our GL BARRIER lineup encompasses a wide array of variations, including transparent barrier film that offers the world's highest level of performance.
This film has many outstanding properties due to the use of TOPPAN's original transparent vapor deposition and coating technologies.

The barrier coating layer and inorganic vapor-deposited layer achieve both stable barrier performance and outstanding eco-friendliness.

GL BARRIER consists of a substrate film (PET, PP, PE, or nylon) laminated with a barrier coating layer and an inorganic vapor-deposited barrier layer (alumina or silica).
Due to this outstanding layer structure combining an original coating layer with a high-grade vapor-deposited layer, the film displays stable barrier properties and is easy to use in post-production processes such as printing and laminating.

GL BARRIER Applications

Flexible Packaging / Retortable Packaging

The outstanding barrier performance prevents the quality of the contents from deteriorating (due to oxidation, drying, etc.), thereby helping to maintain product value over the long term.

Electronics Packaging

Making the packaging transparent enables people to visually confirm what is inside.
The barrier performance matches that of an aluminum-foil structure to reliably protect the contents.

Packaging for Medical & Pharma Goods

Making the packaging transparent helps to prevent misuse, and the outstanding barrier performance prevents the contents from hardening or deteriorating.

Toiletries

Our film prevents aromas from escaping. It is exceptionally easy to process and is even suitable for forming into spout or tube shapes.

Composite Paper Containers for Liquids (EP-PAK, Cartocan, etc.)

By combining GL BARRIER with paper, our environmentally friendly paper packaging enables the long-term storage of liquid contents.

Chilled or Frozen Food Packaging

The excellent barrier performance prevents the deterioration of the contents (due to oxidation, drying, etc.).

We offer an extensive lineup to handle various needs, including both grades that can be used for retort processing and grades that can be used as an alternative to aluminum foil.

Our film is not affected by the temperature of the surrounding environment and demonstrates stable barrier performance.

Our film is not affected by the humidity of the surrounding environment and demonstrates stable barrier performance.

Thanks to its outstanding ability to prevent water evaporation from the contents, our film helps to prevent drying and weight (density) changes.

Water Evaporation Prevention Performance

Our film's outstanding flex resistance enables it to maintain barrier performance even after being bent.

Mono-material Packaging Materials

Mono-material packaging consists of a single material, making it more suitable for recycling than packaging made of composite materials.

Features

GL BARRIER promotes the recyclability of mono-material high barrier packaging.
GL BARRIER is available in both PP and PE-based grades for mono-material packaging. Despite its single material composition, it still retains its high barrier properties and various functions.

Mechanically Recycled PET Grade

The base material contains mechanically recycled PET from the plastic bottles. It promotes the use of recycled resources. The film has high barrier properties by using GL BARRIER technologies.

Features

The film uses 80% of recycled resin in order to reduce the amount of petroleum resources.
TOPPAN’s patented vapor deposition and coating technologies provide the world’s highest level of barrier properties and a wide range of product lineup.
Reducing CO₂ emissions by approximately 17% compared to general trans parent vapor-deposited barrier films.
