Abstract: A method of forming a thermoformed article may include melt extruding polyethylene to form an extruded sheet. The rheological breadth parameter of the polyethylene may change by no more than about 5% after extrusion relative to the rheological breadth parameter of the polyethylene prior to extrusion. The extruded sheet may be thermoformed within a mold to form the thermoformed article. During thermoforming, the extruded sheet may be subjected to solid- state stretching in one or more directions. The thermoformed article may be retrieved from the mold. The polyethylene may have a rheological breadth parameter of from 0.20 to 0.40, a multimodal molecular weight distribution, a polydispersity (Mw/Mn) of from 5 to 18, a density ranging from 0.940 to 0.970 g/cc, may exhibit tensile strain-hardening, or combinations thereof.

Abstract: The present Invention relates to polyethylene films, and to processes for making films. In particular the invention relates to solid state stretched films that may be monoaxially or biaxially oriented. The processes can tolerate high draw ratios and lower extrusion pressures and amperes while producing films having high tensile strength and modulus as well as low shrinkage. The polyethylene used to make the films has a density of from 0.940 to less than 0.960, a molecular weight distribution of greater than 10, a melt flow index ranging from 0.30 dg.min to 1.00 dg.min and a weight average molecular weight of 300,000 or less.
