The BOPP film includes a polypropylene, an absence of a nucleating agent, and an additive blended with the polypropylene forming a polypropylene/additive blend, wherein the additive is potassium stearate.

Use of agents to reduce crystallinity in polypropylene for BOPP applications

A polymer composition adapted for use in injection stretch blow molding may include a metallocene random propylene-based copolymer in the absence of a clarifier. The metallocene random propylene-based copolymer may exhibit a melting point of from 105&#xb0; C. to less than 175&#xb0; C., a recrystallization temperature ranging from 85&#xb0; C. to 100&#xb0; C. as measured by DSC, a microtacticity ranging from 89% to 99%, a molecular weight (Mw) ranging from 170,000 to 210,000, and a melt flow rate of from about 1 dg/min. to about 40 dg/min. A method of forming an injection stretch blow molded (ISBM) article may include providing the metallocene random propylene-based copolymer, injection molding the metallocene random propylene-based copolymer in the absence of a clarifier into a preform, and stretch-blowing the preform into an article.

Injection stretch blow molded articles and random copolymers for use therein

A process includes combining a metallocene catalyzed polypropylene with a nucleator and a slip agent to form a composition, and forming a cast film from the composition. The slip agent may exhibit an increased slip bloom rate within the cast film relative to the slip bloom rate exhibited by the slip agent in an otherwise identical cast film in which the nucleator is not present in the cast film. The cast film may exhibit a coefficient of friction that is less than a coefficient of friction of an otherwise identical cast film in which the nucleator is not present in the cast film.

Use of nucleation to improve slip bloom in metallocene polypropylene resins

Methods for preparing an impact copolymer by selecting a continuous phase polymer having a first melt flow rate and selecting a rubber phase polymeric material such that the final melt flow rate of the impact copolymer is within 2 g/10 min of the first melt flow rate. Impact copolymers made from such methods and films and molded articles produced from such impact copolymers are also included.

Heterophasic copolymer and method for the preparation thereof

Injection stretch blow molded (ISBM) articles and methods of forming the same are described herein. The ISBM articles generally include a metallocene random propylene-based copolymer.

A blown film composition including an impact copolymer polypropylene component and a nucleating agent, wherein the blown film has improved processing and physical properties.

Use of nucleation in ICP resins

Disclosed is a polystyrene based polymer/layered compound nanocomposite for injection blow molding or injection stretch blow molding of articles. The nanocomposite can reduce shrinkage and warpage to the preform during the reheating process compared to neat polystyrene. The incorporation of layered compounds can increase the processability of PS preforms, help improve heating efficiency, and improve bottle mechanical properties. The layered compound can be treated with chemicals or compounds having an affinity with the styrene monomer or polystyrene, thus producing a treated layered compound having an affinity with the styrene monomer or polystyrene. The monomer and the layered compound can be combined prior to polymerization. The polymer and layered compound can be combined by solution mixing in a solvent. The layered compound can also be incorporated into the mixture by compounding a polymer product with the layered compound, or the combination of any of the above three approaches.

Polystyrene nanocomposites for blow molding applications

Disclosed is a method of producing a novel biaxially oriented film having a high diffraction of light, and flexibility. In particular, the invention disclosed provides a method for making an opaque impact copolymer film by stretching in two dimensions an impact polypropylene copolymer. The invention is disclosed to be useful for making a material particularly suitable for a variety of applications including labeling media, food packaging and laminates. Also disclosed is a multilayer film having a first impact polypropylene copolymer layer and a second layer of another polymer wherein the multilayer film has significantly reduced haze. Also disclosed is film produced with a filler that has increased porosity and flexibility.
