Nagase invents recyclable rubber-stamp using PLUSWOOD


Nagase's newly invented environmental friendly wood material "PLUSWOOD" is to be used in the rubber stamp stocks production, which will be launched early 2001.

The wooden stock traditionally used in rubber stamps has fast becoming a problem for environmental protection and has led its price to escalate year after year. A Katsura tree from Hokkaido or an imported Agachius wood is traditionally used for stocks, which usually obtained by felling and therefore, can cause instability both in quality and quantity. Cost for getting the wood material has been increasing year by year and moreover supply is limited due to environment conservation. Price increase on the wooden part of the stamp product lowered profits for stamp manufacturers. Polystyrene and others plastics are hence used in rubber-stamp stocks. Including PS resins.

While it is now not uncommon to find plastic stamp stocks, this technology for recycling stamp stocks is first of its kind developed by Nagase. It is expected to be widely and rapidly endorsed by both the public and private consumers who are supportive of green products. Recycling stocks is quite a sophisticated process and has not been successfully attempted by other industry players. This start up business by Nagase is definitely a value-add to the market. Nagase has a foresight that the general public and government bodies as well as schools will be advocating more on green products as awareness on environmental protection is on the rise.

Nagase will supply the recyclable rubber stamp stocks to Asahi Photo Resin Sales, a seller of photosensitive resins, with whom Nagase ties up and has developed new rubber stamp product branded under "LOGSEAL". This LOGSEAL rubber stamp is recycled from used products and will be on the market sometime in early 2001. LOGSEAL will contribute to the reduction of environmental wastes because it requires no peeling off top coating of stock surface after recovery. This is mainly due to its unique bi-color forming technique used which binds simultaneously with wood grain during manufacturing.

Nagase is targeting about 80% market share of rubber-stamp stock market after a several years period.
