Abstract

A moist smokeless tobacco product for oral use comprises a pre-portioned piece of tobacco material semi-dissolvable, a super-hydrated membrane coating comprising a soluble, non-cross-linked component and an insoluble, cross-linked component, and a texture component. The tobacco material comprises moist smokeless tobacco. The texture component reduces the slipperiness and/or increases the friction of the moist smokeless tobacco product when placed in a user'"'"'s mouth.
