摘要： A thermoplastic polymer composition comprises a polyethylene polymer composition and a salt of bicyclo[2.2.1]heptane-2,3-dicarboxylic acid. The polyethylene polymer composition can have a Melt Relaxation Index of 2 or greater. A method for molding a thermoplastic polymer composition comprises the steps of (a) providing an apparatus comprising a die with an annular orifice, a means for blowing pressurized fluid into a tube exiting the die orifice, and a means for drawing and collecting the tube; (b) providing the thermoplastic polymer composition described above; (c) heating the thermoplastic polymer composition to melt the thermoplastic polymer composition; (d) extruding the molten thermoplastic polymer composition through the die to form a tube; (e) blowing a pressurized fluid into the tube to inflate the tube while simultaneously drawing it; (f) allowing the film to cool; and (g) collecting the film.

摘要： The present disclosure relates to a multifunctional film for a vacuum bag that may include a flexible barrier film that may include a textured surface. The multifunctional film may further include a release coating overlying the textured surface of the flexible barrier film. The multifunctional film may further have an oxygen (O2) permeability of not greater than about 1100 cc/(m2-day-atm) and a stability rating of not greater than about 90%, where the stability rating is defined as the maximum percent decrease in elongation at break as measured using ASTM D882 after being exposed to a temperature of 200 °C for 12 hours.

摘要： A thermoplastic polymer composition comprises a polyethylene polymer composition and a salt of bicyclo[2.2.1]heptane-2,3-dicarboxylic acid. The polyethylene polymer composition can have a Melt Relaxation Ratio of 1.5 or greater. A method for molding a thermoplastic polymer composition comprises the steps of (a) providing an apparatus comprising a die and a mold cavity; (b) providing the thermoplastic polymer composition described above; (c) heating the thermoplastic polymer composition to melt the thermoplastic polymer composition; (d) extruding the molten thermoplastic polymer composition through the die to form a parison; (e) capturing the parison in the mold cavity; (f) blowing a pressurized fluid into the parison to inflate the parison and conform it to the interior surface of the mold cavity; (g) allowing the molded article to cool so that the molded article retains its shape; and (h) removing the molded article from the mold cavity.
