The technology's not commercial yet, and it certainly has its skeptics. Test results show that thermal and barrier properties are enhanced significantly by blowing PET into heated molds and cooling with LN2 delivered by a unique new system.
Single-facing machinery helps Longview Fibre's Milwaukee plant bond the medium to the liner without pressure marks. Meanwhile, the company's new six-color flexographic press produces images that customers say rival preprint.
Superior thermal properties, chemical resistance, and high barrier to oxygen transmission have made PEN and other naphthalate-based materials irresistable for a hot-filled isotonic drink and for citrus juices.
