Abstract:
A method for processing a linear polyethylene into a film comprising:a) selecting a linear polyethylene from the group consisting of linear low density polyethylene (LLDPE), metallocene linear low density polyethylene (m-LLDPE), high density polyethylene (HDPE), plastomers, medium density polyethylene (MDPE), ultra high molecular weight-high density polyethylene (UHMW-HDPE) and combinations thereof;b) selecting a surfactant, wherein said surfactant is an aliphatic sulfonate salt or branched or straight chain hydroxyl substituted non-aromatic alkyl sulfonate salt, wherein a cation of said salt is selected from the group consisting of Na, K, and Li, wherein said aliphate group is a C.sub.6 -C.sub.30 branched or straight chain alkenyl, and combinations thereof;c) placing an amount of said surfactant into said polyethylene sufficient to reduce melt fracture; andd) melt processing said polyethylene and said surfactant to form a film.
