POLYOLEFIN BOTTLES AND METHOD FOR MAKING SAME

摘要

Bottles useful as pharmaceutical containers are provided are which include molding compositions having polyolefin of a density of at least about 0.89 g/cm<3> which may be formed from a catalyst comprising a metallocene and which may have a 60 DEG specular gloss of at least about 25. A method for forming a blow molded bottle and bottles formed from that method are also provided. The bottles are useful as pharmaceutical containers, and the method includes providing a molding composition having a polyolefin to a blow mold defining a blow molding chamber, wherein the polyolefin has a density of at least about 0.89 g/cm<3>; and blow molding the molding composition in the molding chamber while allowing air and gases to escape outwardly through the molding chamber to form a bottle, wherein the molding chamber has a metal having a plurality of pores and the air and gases escape outwardly from the molding chamber through the pores in the metal.
