Prevention of penetration by gases

Transparent Super Gas Barrier Film

Provides high gas barrier capability almost comparable to that of glass, preventing degradation of organic materials

This gas barrier film prevents the degradation of organic materials, eliminating the effects of even infinitesimal quantities of moisture and oxygen. Flexibility and barrier performance rivaling glass are combined using an organic/inorganic nano multilayer structure with a dense inorganic layer and protective organic layers that also provide flexibility.

Organic/inorganic nano multilayered structure

By combining organic and inorganic characteristics, this film maintains barrier function, preventing cracks and other damage to the inorganic layer.

Photovoltaic Backsheet

This photovoltaic backsheet features high durability and excellent adhesion with respect to the encapsulant

High durability was achieved by using a base of special water-resistant PET film. A mono-sheet backsheet was created by using high-precision coating technology to add a functional layer that firmly adheres to the EVA (encapsulant).

Hydrolysis resistant PET manufacturing technology

In order to improve hydrolysis-resistance performance, a special PET resin was polymerized. We developed our own technology for manufacturing film without allowing decomposition.
