1.Grey Back (also named CCNB,clay coated news back in North America market);
CCNB board is the main material for gift box printing jobs. It is wrapped by surfacing paper on grey side, and the white side is inside of box, so it is not necessary to apply lining paper any more, which could save much production time and costs. But for some deluxe gift boxes, the lining paper could also be applied to make a colorful inner of box. The thickness is normal above 0.5mm for gift boxes. The 230gsm - 500gsm CCNB is regularly for folding box printing jobs.
CCNB means Clay Coated News Back. As a paperboard made of recycled paper pulp, CCNB has one side coated white color, and another side uncoated grey color. The side coated is available to print full colors, if the coating is good, then the colors printed should be also good accordingly, Another side uncoated is also okay for printing, but the result is not good because of uncoating and coarse surface. As a main board material, CCNB is usually used for packaging printing, such as shoe boxes, gift boxes, packaging boxes and folding boxes etc. The base weight of CCNB could be 230gsm - 500gsm and 0.5mm - 3mm.
