A FILM-FORMING POLYETHYLENE COMPOSITION CONTAINING IN INTIMATE DISPERSION IN A POLYETHYLENE BASE RESIN AN EXUDABLE UNSATURATED FATTY ACID AMIDE POLYETHYLENE SLIP AGENT HAVING A MELTING POINT BETWEEN AOBUT 20*C. AND 75*C., AND A BOILING POINT OF AT LEAST 225*C. IN AN AMOUNT BETWEEN ABOUT 0.001 TO 0.15 PART BY WEIGHT, AN EXUDABLE WAXY FATTY ACID AMIDE HAVING A MELTING POINT BETWEEN ABOUT 90*C. AND 150*C., AND A BOILING POINT OF AT LEAST 225*C. IN AN AMOUNT BETWEEN ABOUT 0.001 TO 0.15 PART BY WEIGHT, AN ANTIOXIDANT FOR POLYETHYLENE IN AMOUNTS BETWEEN ABOUT 0.001 TO 1.0 PART BY WEIGHT, A FINELY DIVIDED SILICEOUS MATTER IN AN AMOUNT BETWEEN ABOUT 0.001 TO 1.0 PART BY WEIGHT HAVING AN AVERAGE PARTICLE SIZE BETWEEN ABOUT 0.5 TO ABOUT 7 MICRONS, A POLYETHYLENE HAVING DIFFERENT MELT FLOW CHARACTERISTICS THAN THE BASE RESIN SELECTED FROM THE GROUP CONSISTING OF POLYETHYLENES HAVING A MELT INDEX AT LEAST 10 PERCENT HIGHER THAN THE MELT INDEX OF THE POLYETHYLENE BASE RESIN, POLYETHYLENES AHVING A HIGHER DENSITY THAN THE POLYETHYLENE BASE RESIN, AND MIXTURES THEREOF IN AN AMOUNT BETWEEN ABOUT 0.5 TO 10 PARTS BY WEIGHT AND A FILM GRADE POLYETHYLENE BASE RESIN HAVING A MELT INDEX BETWEEN ABOUT 0.5 AND 12 IN AN AMOUNT SUFFICIENT TO MAKE 100 PARTS BY WEIGHT OF SAID COMPOSITION.
