The invention is an improved apparatus for the application of plastics stretch films to materials and items to be packaged and secured as a unit or packaged and secured to a shipping and transporting means. The apparatus consists of a pair of insertable adapters for the ends of a cylindrical core which holds a supply of plastic stretch films and a pair of tubular-like grip means for said insertable adapters. The grip means serves as a control means for the speed of paying out the plastics stretch film material, and as a means for applying tension on the film during the course of applying it to materials and items. The apparatus may be used for manual or machine application of film to materials. Brake shoe equivalents of the grip means may be used for machine applications.
