Patent ID: 8158849

Claim:
A method of forming a roll of thermoplastic elastomeric film resistant to blocking and subsequently utilizing 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) substantially concurrent to said on-line formation, applying an anti-blocking agent in a fluid or molten state via a spray applicator directly to at least the first surface of the thermoplastic elastomeric film so as to form a treated surface with a discontinuous formation of the anti-blocking agent comprising discrete droplets disposed on the treated surface, c) 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, and d) separating the gathered film so as to result in the detachment of at least some portion of the gathered film that was in contact with itself.
