An economical alternative to cotton board, made from high quality chemically purified wood fibres. High in alpha cellulose, buffered with calcium carbonate to resist air-borne pollution and to maintain a neutral environment around the object.
The paper is neutral sized internally with AKD and externally with starch. It is laminated with EVA plasticiser-free adhesive which is more resistant to acid hydrolysis than other cheaper synthetic adhesives. This is important if you are looking for the maximum level of protection because if the adhesive breaks down and ‘off gases’ ie. acetic acid in the micro-environment of a frame or a box the object enclosed will be damaged. The board may be easily cut and gives a smooth edge which will maintain its colour without yellowing throughout the life of the board. The board is suitable for ink and wash line decoration because of the surface sizing of the paper.
