GL BARRIER

A transparent vapor-deposited barrier film that has a leading share of the global market and is used in more than 45 countries and regions.

Our GL BARRIER lineup encompasses a wide array of variations, including transparent barrier film that offers the world’s highest level of performance.

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 Features

Excellent Barrier Performance

Protects contents from changes in storage conditions, such as moisture absorption, drying, and decomposition.

Eco-friendly

When used as an alternative to aluminum foil, our film can reduce the volume of existing packaging.
When used as an alternative to aluminum foil, our film can also reduce the volume of CO₂ emissions associated with manufacturing.
When used as part of functional monomaterial packaging with outstanding barrier performance, our film can increase recyclability.
Our film leaves almost no residue upon being incinerated and does not generate hazardous gas.

Highly transparent and non-conductive

Metal detectors, microwave ovens, and RFID can be used.
Thanks to its transparency, our film can be used to showcase the contents of packages.

Extensive Lineup

Various grades are available depending on the purpose of use.

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 and pharmaceutical 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.).
