Abstract
A puncture sealant package for incorporation into a pneumatic tire is formed by coextruding a puncture sealant, and a skin forming material. The ribs are formed in an initially circular package profile as chords. After flow in a sheet die, the chords form divider ribs making small angles with the encapulating skin. The compartments formed by the ribs prevent flow of the sealant toward the center of a tire.
