Tough, flexible, translucent sheets that are made of bacterial cellulose. Bacterial cellulose is produced as a secretion from bacteria fed a sugary solution (in this case pineapple juice) in a warm bath. These sheets are made from remnant cuts from the larger sheets, with the majority of the sheet used to produce beauty care products. The leftover parts are pressed together with a roller forming a single homogenous sheet and dried in a hot-air oven. Finally, they are rigidized with hard paraffin, much in the way that waxed cotton is treated, making it impervious to water. The resulting membrane is claimed to be equivalent in stiffness to aluminum for the same weight, has a leather-like hand, and good mechanical properties such as tear strength and stitchability. They are offered in 290 x 200 mm (11.4 x 7.9 in) and in a nominal thickness of 1.2 mm (0.05 in). It can be customized in color, texture, thickness (give the bacteria more time) and in size (use a larger bath), giving it advantages over leather. The sheets can be used in many of the places that leather is currently used, for example as a fabric for bags and upholstery, and for accessories.
