Preston Board are established chipboard manufacturers and suppliers in the UK. Unlined chipboard is often referred to as solidboard, greyboard or chipboard. They are all derivatives of the same material being produced using 100% recycled waste paper which is pulped down and formed into jumbo reels.
As chipboard manufacturers and suppliers, Preston Board can produce reels on the board machine up to 1250micron (1.25mm) thick. For thicker material the reels have to be laminated together using water based adhesive in a secondary process using a purpose built board laminator.
Unlined chipboard is produced using a higher content of brown waste cardboard made up of material like old corrugated boxes, for example. This gives the finished product a brown appearance.
