ABSTRACT:
Heat sealed articles and heat sealable films comprising a polymer blend of a first polymer having a narrow molecular weight and composition distribution and a second polymer having a broad molecular weight distribution and composition distribution. The articles and films have significantly improved physical characteristics and remarkably low heat seal initiation temperatures, high seal strength, high hot tack and therefore provide improved processibility and higher line speeds on commercial heat sealing equipment.
