ABSTRACT:
A coated web or composite having improved flexibility. The coated web of the present invention comprises at least one layer and preferably at least two layers. The layers comprise a fibrous web located or embedded with polymeric composition. The coated web is flexed sufficiently over at least a portion of the web surface to have improved flexibility properties. The web can be flexed in a single direction along the surface or randomly along the whole surface. Preferably, the web is flexed sufficiently to form a plurality of permanent creases or wrinkles. The coated web has improved flexibility, and at the same time, impact resistant properties, such as ballistic resistance, are substantially maintained compared to an unflexed web.
