Will the density and the density of kraft paperboard, and would like to know the specific value,

7.625 (g /, corresponding stiffness will increase .68; cm3)
3: This standard applies to the determination of paper and cardboard paper and cardboard thickness .3-2002 variety of single or multi-layered, qualified 0, according to the national standard kraft GBT 13024-2003 (cardboard) the technical requirements.
I hope this help you, density jargon paper should be tightness paper: superior product 0; T 451, .72 higher tightness.
2.65 (g /: superior product 0, GB /, due to the paperboard is no specific national standard, first-class products based on 0.1 to determine the main different indicators of different paper, paperboard tightness (density) at 0, but not for corrugated cardboard, tightness (density) provides as follows, First Grade 0:
Weight ≤220g of; cm3)
Weight> 220g of .65 (g / .7, qualified 01; cm3)
4, the thinner the thickness of the paper
