By maximizing our core co-extrusion technology, Gunze became the first in the world to commercialize a biaxially-oriented nylon film with a 7-layer structure of five different compositions using a T-die. Called GNY, this special film for gas barrier applications has enjoyed steadily increasing sales since it was first released to the market in 1991, largely through its reputation for eco-conscious functionality. At present, Heptax is not only used for confectionery, rice cake, dairy product and meat packaging but also for medical and industrial applications. Exports are also being promoted for a steadily expanding marketplace.
