Abstract: A method of selecting polyethylene components for a polyethylene composition having an improved Vicat softening point comprising blending at least a first polyethylene having a first density and a second polyethylene having a second density to form the polyethylene composition, wherein the first density is greater than the second density, and determining a first Vicat softening point (V1) of the composition measured, and calculating a second Vicat softening point (V2) of the composition using the formula V2=[?1n{W1(Vicat softening point of the first polyethylene)+W2(Vicat softening point of the second polyethylene) . . . Wn(Vicat softening point of the nth polyethylene)}], wherein W1 is the weight fraction of the first polyethylene, W2 is the weight fraction of the second polyethylene and Wn is the weight fraction of the nth polyethylene, n ranges from 2 to 10 and W1+W2 . . . +Wn=1.0; comparing V1 and V2; selecting the polyethylene components such that V1 is less than V2 for the polyethylene composition.

Abstract: The invention relates to a film structure combining a metallocene-rich layer and an HDPE-containing layer. A preferred embodiment is a structure having metallocene-rich skin layers and an HDPE-containing core. The structures of the invention are particularly useful for collation shrink.

Abstract: The invention concerns the use of fatty acid amides as antiblock additives for film-forming compositions, eliminating the necessity of inorganic additives.
