Abstract
The invention provides an extruded caulk strip comprising a shaped caulk body in melt fusion contact with one major surface of a protective strip formed of substantially amorphous, non-tacky, conformable, thermoplastic, film-forming polymeric material. The extruded caulk strip is formed by melt extruding the thermoplastic film-forming polymeric material to form a continuous plastic strip, melt extruding a caulk mass to form a shaped caulk body, and contacting one of the major surfaces of the strip with the shaped caulk body while the contacting surfaces of the strip and the caulk body are in a plastic state capable of self fusion on contact.
