KEIWA was founded in 1948. Initially, it supplied waterproof paper to the textile industry supporting Japan's postwar reconstruction and grew to become a top processed paper manufacturer in western Japan. During the high-growth period, it supplied moisture-proof packaging materials, process materials, and protective sheets for natural gas and oil pipelines, and established its three core technologies: Sheeting, Laminating, and Coating. Later, it invented the diffusion film 'Opalus' for the display field.
