Zusammenfassung:An additive for high density, standard density, or low density polyethylene films, the additive comprising ethylene vinyl acetate wherein the ethylene vinyl acetate is added in an amount sufficient to increase the laser absorption of the polyethylene film and results in a film for laminating to a sealant layer to produce packaging, the packaging being recyclable and openable via tearing without tools such as a scissor or knife. The polyethylene with additive layer can be formed by co-extrusion of the polyethylene and ethylene vinyl acetate to form a filmor by blending of the polyethylene and ethylene vinyl acetate components for forming the film.
