Abstract

A holder for dispensing stretch film from a roll comprises a cylindrical body and an arbor rotatably supported on the body. A flexible grip having internal ribs covers the body and the arbor, so that one can, by applying finger pressure to the grip, brake rotation of the arbor and thus control film tension.
