Premier™ Archival Folding Boxboard - Grey/White
0650 Micron 520gsm 1040mm x 1473mm - 20 sheet/pk

This duplex colour solid centre conservation boxboard is designed for the production of solid board boxes and folders to protect collections from the damage caused by handling atmospheric pollution fire and flood disasters.
The board is laminated from Conservation by Design Heritage Archival pHotokraft™ papers which pass the Silver Tarnish Test and Photographic Activity Test (PAT). They are acid-free and lignin-free with a high percentage of bleached long kraft fibres.
This board which meets the most stringent requirements of long term archival storage for conversion into boxes or folders 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’ in the micro-environment of a box the contents can be damaged.
Premier™ Archival Folding Boxboard - Solid Centre offers a controlled ‘microenvironment’ for books papers photographs and other fragile items; adding to the physical protection a slightly alkaline environment helps to counteract any acidity in boxed materials. Reducible sulphur content of the board comfortably meets the ANSI American standard for the safe storage of photographic materials.
The greatest care has gone into ensuring that this material meets detailed archival standards in terms of chemical composition whilst offering excellent folding strength and rigidity. The coloured paper surface of the board will not bleed and is resistant to fading dirt grease and abrasion while the smooth white interior surface is designed to minimise abrasion of box contents.
Please note: Products made from corrugated board do not offer the same protection from fire or water as Solid Centre Board.
