The PET Art features a new combined dryer unit that replaces the separate drying stages of the previous recoSTAR. The extruder is also a new design, with a length/diameter ratio of 24, down from 40. The increased capacity in the solid state polycondensation reactor ensures thorough decontamination and cleansing, eliminating the need for a specific degassing station. A melt pump was added between the extruder and pelletizer. After crystallization and solid-state polycondensation, material moves through an energy recovery station that harnesses the heat of the warm pellets.

The changes result in a 25% reduction in energy use relative to the previous model, while increasing capacity from 1.8 to 2.1 ton/hr. Starlinger also reported that the machine requires 46% less maintenance time thanks in part to its dry vacuum pumps and open-loop desiccant air flow. Continuous automatic monitoring of process parameters has been implemented to ensure product quality, especially important for producing food-safe material.

Starlinger expects the energy savings, along with improved uptime and ease of operation, will reduce its customers’ overall production costs by 21%.

Starlinger displayed both the extruder and combined drying unit at K Show, and demonstrated a full recoSTAR PET art line at its factory in Schwerin after the show.

Combining existing technologies for base design and mold venting offer savings to users of all types of stretch-blow molding machines.

New Process Pilot+ from Agr International offers faster response and flexible goals for keeping PET bottles on spec.

SABIC’s new WF0061BiQ is the latest addition to the company’s portfolio of chemically upcycled LNP Elcrin iQ materials.
