Ethylene-based polymers are characterized by a melt index less than 1 g/10 min, a density from 0.94 to 0.965 g/cm.sup.3, a Mw from 100,000 to 250,000 g/mol, a relaxation time from 0.5 to 3 sec, and an average number of long chain branches (LCBs) per 1,000,000 total carbon atoms in a molecular weight range of 300,000 to 900,000 g/mol that is greater than that in a molecular weight range of 1,000,000 to 2,000,000 g/mol, or an average number of LCBs per 1,000,000 total carbon atoms in a molecular weight range of 1,000,000 to 2,000,000 g/mol of less than or equal to about 5 and a maximum ratio of .sub.E/3 at an extensional rate of 0.1 sec.sup.1 from 1.2 to 10. These polymers have substantially no long chain branching in the high molecular weight fraction of the polymer, but instead have significant long chain branching in a lower molecular weight fraction, such that polymer melt strength and parison stability are maintained for the fabrication of blow molded products and other articles of manufacture. These ethylene polymers can be produced using a dual catalyst system containing a single or two atom bridged metallocene compound with two indenyl groups, and a single atom bridged metallocene compound with a fluorenyl group and a cyclopentadienyl group.

A resin member contains a copolymer of ethylene and an olefin having 3 or more carbon atoms, and a fatty acid ester.

A sealing device generally includes a rotatable support cylinder having an outer, circumferential surface and a heating element disposed about such surface and secured thereto such that the heating element rotates therewith. The heating element is coiled about the outer surface of the cylinder in the form of an overlapping helical pattern. Juxtaposed film plies may be sealed together by bringing the sealing device into rotational contact with the juxtaposed film plies and heating the heating element to a temperature sufficient to cause the film plies to seal together.
