DEFINITION

Classification: 428/219

(under subclass 98) Product in which a physical characteristic of the overall web or sheet is recited in terms of its weight per unit area of the product.

(1) Note. Since weight per unit area and a physical dimension are related, cross-referencing between this subclass and the succeeding one has been minimized. Both subclasses should be considered in the search.
