ABSTRACT:
A multilaminar high density polyethylene (HDPE) film is provided having high biaxial orientation. The film includes a HDPE substrate, at least one outer layer of a propylene copolymer, and at least one layer of an adhesion promoter material positioned between the outer layer and the HDPE substrate, to efficiently mediate adhesion therebetween. The adhesion promoter is preferably a polyethylene material having a density lower than that of the HDPE base material. Preferred adhesion promoter materials include very low density polyethylene (VLDPE), high pressure low density polyethylene (HP-LDPE), linear low density polyethylene (LLDPE), and medium density polyethylene (MDPE). The film is high biaxially oriented, being, stretched in the machine direction to a degree of from about 5:1 to about 8:1, preferably from about 6:1 to about 7:1, and stretched in the transverse direction to a degree of from about 6:1 to about 15:1, preferably from about 9:1 to about 13:1.
