ABSTRACT:
According to the present invention, it has been found that blended polyolefin resins containing linear low density polyethylene copolymers (LLDPE) are advantageous in the manufacturing of thermoplastic films and bags. The blended polyolefin resins are particularly well suited for making seamless-wall handled strap bags from thin tubular film consisting essentially of a homogeneous blend of HDPE, LLDPE, and ordinary branched LDPE. Superior physical properties of blown film from this blend permits the fabrication of economical carrying bags from thinner film, resulting in substantial material savings.
