ABSTRACT:
An improved method of manufacturing blown polyolefin films with increased bubble stability and higher blown film production rates is disclosed. A method in which the amounts and ratios of known antioxidant polymer film additives (phosphites and phenolics) are controlled to provide limited long chain branching (LCB) and greater rheological breadth in a polyethylene melt to improve both processing characteristics and mechanical properties in the resulting film.
