    摘要： A high density polyethylene (HDPE) film is provided having high-biaxial orieniation. The film includes HDPE having a density of at least about 0.940, and a melt index of from about 0.5 to about 10. The film is stretched in the machine (longitudinal) direction to a degree of from about 5:1 to about 8:1, preferably from about 6:1 to about 7:1. The film is also stretched in the transverse (lateral) direction to a degree of from about 6:1 to about 15:1, preferably from about 9:1 to about 13:1. Preferably, the film has an orientation imbalance, with a higher degree of transverse orientation than machine orientation. Skin layers such as heat seal layers can be provided. Preferably, the film contains one or more layers of a casting promoter material employed to promote casting of a high gauge HDPE sheet subsequently high biaxially oriented to provide the film. The film can also be cavitated, or otherwise modified (e.g., corona-treated, coated, metallized, etc.) to provide films suitable for special applications. The film of the invention has superior properties, including lower water vapor transmission rate, better dead-fold, higher tensile strength, and consistent gauge profile. Also provided is a method for making the biaxially oriented film.

    摘要： 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.

    摘要： Good extrusion at high reduction ratios is obtained with a non-melt-fabricable tetrafluoroethylene fine powder resin whose particles have an inner portion and an outer portion, each portion being composed of a copolymer of tetrafluoroethylene and a selected comonomer, in which the comonomer content of the copolymer in the inner portion is greater than the comonomer content in the copolymer in the outer portion. Such particles are obtained by polymerizing tetrafluoroethylene and a desired amount of the selected comonomer in an aqueous dispersion medium, then lowering the amount of comonomer available, and continuing the polymerization.
