“Oper”, which is a waterproof laminated paper, has been made by Nippon Paper Industries since 1988. “Oper” maintains the same characteristics as general papers, like “softness”, “printability”, “convertibility”. Now it is widely used in a commercial printing business and in a converted paper business.
At the early stage of development, “Oper” had some problems in quality, which were caused by the effect of roughness and moisture of base paper onto the surface morphology of laminate layers. We report here how we coped with these problems.
We also report the development of our new products, “The Poster”, and “Oper MDP”. “The Poster”, which is the product mainly used for posters, has improved ink drying property which was the strongly required property by a market. And “Oper MDP” was developed for full-color laser beam printer, which is one of the on—demand printing field which is remarkable growth field in recent years.
And we introduce our latest consideration to the environment.
