PP bottles made with SX NX 8000E have a better clarity, better gloss both inside and outside, lower haze, a low yellowness index, and an overall fresher look.

“We worked for several years with machine manufacturers, resin producers, converters and brand owners to optimize this new product, to ensure it delivered the desired properties without compromising transparency or machine production speeds,” said Milliken Senior Development Engineer Bart Gabriels.

The optical properties of SX NX 8000E resins also are less dependent on processing, he noted. Therefore, standard mold surface finishes (such as a glass-blasted finish) and processing temperatures for PP can be used without compromising quality. “With high MFR grades (MFR around 3),” Gabriels said, “this clarifier delivers a complementary effect that results in excellent optics and productivity.”
