主权项 1. A blow molding process of making a container, comprising the steps of: a) affixing a precursor container form into a blow molding mold, wherein said precursor container form is a parison or preform, i) wherein said precursor container form comprises a layer, wherein said layer comprises: 1) from about 86% to about 99.99%, by weight of said layer, of a thermoplastic material selected from the group consisting of polyethylene (PE), polypropylene (PP), and a combination thereof; and2) from about 0.01% to about 5%, by weight of said layer, of an additive, wherein said additive has a Surface Tension Value of from about 0.1 to about 50 m*N/m; andii) wherein said mold comprises an inner surface configured to receive the expandable precursor container form, wherein at least a portion of said mold has a SPI finish standard selected from the group consisting of A-1, A-2, A-3, B-1, B-2, and B-3; and b) blowing into said precursor container form as to expand said precursor container form against said inner surface of said mold thereby forming the container.
