    Abstract: A polymer based composition for fabricating into articles is described. The composition comprises: a polypropylene in an amount by weight from 40-90% of the composition and having a melting temperature greater than 130 DEG C; a radio frequency susceptible polymer in an amount by weight from 5-50% of the composition and having a dielectric loss greater than 0.05 at 1-60 MHz and ambient temperature to 250 DEG C, the susceptible polymer being selected from (1) polymers containing at least one segment selected from the group consisting of urethanes, esters, ureas, imides, sulfones, and amides, and (2) ethylene copolymers having 50-85% ethylene content copolymerized with at least one monomer selected from the group consisting of acrylic acid, methacrylic acid, ester derivatives of acrylic acid with alcohols having 1-10 carbons, vinyl acetate, and vinyl alcohol; a compatibilizing polymer in an amount by weight from 5-30% of the composition, the compatibilizing polymer conferring compatibility between the radio frequency susceptible polymer, and the polypropylene, the compatibilizing polymer being a styrenic block copolymer with hydrocarbon soft segments, and wherein the composition has an optical haze value of less than 30% for the composition processed into a film of about 0.299 mm in thickness measured in accordance to ASTM D-1003, a mechanical modulus of less than 2758x10 Pa when measured according to ASTM D-882 and the composition exhibits no strain whitening after being strained at moderate speeds of about 50 cm per minute to about 100% elongation.

    Abstract: An apparatus for sealing a web of film in a packaging machine. The apparatus includes a sealing bar for heating a web of film to a temperature sufficient to melt at least a portion of the web of film. The sealing bar includes a surface that directly contacts the web of film and does not include a release layer. The surface includes thereon a measuring member for measuring the temperature of the molten area of the film. The apparatus further includes a cooling member for cooling the melted portion of the film to its crystallization point during a cycle time of the packaging machine.
