ABSTRACT:
Blended polyolefin resins containing linear low density polyethylene copolymers (LLDPE) are disclosed for making seamless-wall handled strap bags from thin tubular monolayer film consisting essentially of a homogeneous binary blend of resins. The improved resin blend system employed in this invention contains a predominant amount of highly-branched low density polyethylene structure. A minor amount of LLDPE constitutes the other resinous component, preferably in the amount of 10 to 40 parts by weight per 100 parts of polyolefin resin. The LLDPE resin may comprise a copolymer of ethylene with at least one alpha-olefin having 4 to 12 carbon atoms, and having a density less than 0.94.
