Abstract:
1. A method of forming a roll of thermoplastic elastomeric film resistant to blocking, and using said film, said method comprising the steps of: a) providing a thermoplastic elastomeric film having a first surface and a second surface in a continuous manner by on-line formation by extrusion, b) following formation of the film by extrusion, applying an anti-blocking agent in a molten state to at least the first surface of the film to form a discontinuous formation of said anti-blocking agent on said first surface, and thereby form a treated surface, and c) following formation of said treated surface, gathering the film on a roll to form a bulk roll having rolled layers of the film with the treated surface in contact with the second surface.
