]} and thus creating a sheet with very low porosity . This is then passed between hard pressure rollers ( supercalendered ) to further increase the density, creating a paper called glassine . The glassine is treated with starches , alginates or carboxymethyl cellulose (CMC) in a size press to fill pores or treat the paper chemically to make it fat repellent. Basis weights are usually 30?50 g/m ². ^[1]
