  • Bottles made from metallocene polypropylene for delivery of fragrances
    Publication number: 20070042149
    Abstract: Bottles made of metallocene polypropylene (mPP) for storage and dispensing reservoirs for fragrance compositions, in particular fragrance oils, are described. The mPP bottles can be used in warmer units for slow release dispensing of the fragrance therein. The metallocene polypropylene bottles can be produced by extrusion or injection blow molding, injection molding, injection stretch blow molding (single or two stage), or other suitable molding process. The mPP bottles may optionally have at least one barrier coating layer and/or adhering layer. The mPP bottles may optionally be fluorinated. The mPP bottles have good clarity and possess the required physical properties needed when the bottles are filled on a production line.
