Japan—Toyochem Co. Ltd., a member of the Toyo Ink Group of Japan, has developed a new series of biodegradable pressure-sensitive adhesives (PSAs). Marketed under the Cyabine™ series of polyurethane PSAs, the newly developed product is suitable for materials for the packaging, construction, agriculture and other industries where the use of biodegradable or recoverable materials are preferred.
In recent years, there has been growing interest in reducing plastic waste, in particular with regard to the development of biodegradable materials that reduce the use of petroleum and its negative impact on the environment. In many countries, industrial waste generated from fields such as civil engineering, forestry and agriculture need to be recovered or decomposed naturally without imposing a burden on the environment. While the base paper or film substrates used in recovered products are biodegradable, the additives such as adhesives traditionally used to coat or treat them are not, resulting in disposal issues.
