ABSTRACT:
A multi-layered, handled plastic bottle that substantially resists the absorption and oxidation of essential oils, flavoring components, and nutritional components, e.g. peel oil, d-limonene, and l-ascorbic acid (Vitamin C), found in various beverages such as fruit juices and particularly citrus juices. In a particularly preferred embodiment, the plastic bottle having an integrally-formed handle is made by blow-molding an extruded parison having an outer polyolefin layer, and intermediate adhesive layer, and an inner product-contacting layer of a polyester material such as polyethylene terephthalate. In another particularly preferred embodiment, the plastic bottle is extrusion blow-molded from a four-layer parison comprised of an outer polyolefin layer, an intermediate adhesive layer, an inner polyester layer, and a scrap or regrind layer comprised of a blend of these three layers recovered from the flash removed from the finished bottle. Also disclosed is a method of and an apparatus for making multi-layered, handled plastic bottles of the present invention.
