less than 10 minutes. It is aimed at applications in extruded PET sheet and films using degassing extruders. It can eliminate varying levels of input moisture that can cause variation in the extrusion process.
Fast change A highlight of the Windmöller & Hölscher (W&H) stand is its Turboclean module, which allows automatic material changeover on its Varex II blown film lines – which will be demonstrated using a five-layer POD blown film for lamination and collation shrink film. W&H says the Turboclean module can increase

Ad Star sacks are typically used to package dry bulk goods such as cement or fertiliser. The sacks are very tight, and prevent product loss during handling, transport, and storage. Fabric for the sacks is woven on high-speed circular looms, and the company will display its RX 6.0 model at the show. In Starlinger’s showroom in Taicang, visitors will see live demonstrations of two other lines used in sack production: the coating line LamiTec LX, and the conversion line Ad Star Kon. Visitors will also get a first-hand impression of the patented Ad Star hot-air sealing process, which works without the use of glue.

changeover on its Varex II blown film lines
Banging the drum Kreyenborg Plant Technology of Germany will present two new products – IR-Clean and PET- Booster – which are both based on its IRD Infrared Rotary Drum. The IRD is used to crystallise and dry a wide
variety of virgin and regrind polymers, and by eliminating the need for hot or dry air, can deliver energy savings of around 30%. IR-Clean decontaminates post-consumer PET
flakes for direct food contact products – in compli- ance with US FDA regulations. It produces clean flakes using the general crystallisation and drying process of the IRD concept. The flakes are treated under permanent exchange of surface in combina- tion with high temperatures, but without any vacuum systems. IR-Clean is intended to be used in combination with all extrusion concepts and is ideal as an economic retrofit solution for existing PET sheet lines, says the company. Meanwhile, PET-Booster is a continuously
operating system that crystallises and dries PET in 44 FILM & SHEET EXTRUSION | April 2018

productivity due to short flushing times and fast material changes – shrinking order change times from 40 minutes to around 12 minutes. It is automatically included with the Varex II – but is now also available as a retrofit on any of the company’s blown film lines. The company says that retrofitting the Turboclean module to machines made after 2010 should take no longer than two days.
With it, the extrusion system completes the
material change almost completely automatically. Work steps are now automated and parallel, rather than having to be changed step-by-step, by a machinery operator. By combining a three-layer Varex II with inline-
MDO stretching unit, W&H offers a machine configuration to make very thin breathable diaper back sheet film of only 12g/m2
