117 results about "Glassine" patented technology

Glassine is a smooth and glossy paper that is air, water, and grease resistant. It is usually available in densities between 50–90 g/m². It is translucent unless dyes are added to color it or make it opaque. It is manufactured by supercalendering: after pressing and drying, the paper web is passed through a stack of alternating steel and fiber-covered rolls called a supercalender at the end of the paper machine such that the paper fibres flatten facing in the same direction.
