Film Technology W&H’s latest technology at Chinaplas 2018 At Chinaplas, German machine manufacturer Windmöller & Hölscher (W&H) will be presenting a special highlight, Turboclean, for the automatic material changeover on its Varex II blown film lines, which will be demonstrated using, by way of example, a five-layer POD blown film for lamination and collation shrink film. Furthermore, with the production of breathable diaper film on the rise, W&H’s three-layer system Varex II with Inline-MDO stretching unit, offers a machine configuration for the production of a particularly thin breathable diaper back sheet film of only 12 g/m² - a product that is predominantly produced in cast film extrusion and with a higher basis weight. However, the focus will also be on the manufacture of surface protection films, FFS films, barrier films with up to 11 layers and nanolayer stretch films with up to 55 layers, as they can be produced on the Filmex cast film extrusion line. The Aquarex upside-down line for the production of films for infusion bags should also attract considerable W&H’s Varex II with Turboclean for interest. what is said to be the fastest material Other changeover products are flexographic and gravure printing presses with a special focus on VOC reduction (reduction of volatile organic compounds) and the fastest changeover times, as well as in the area of industrial sacks made from paper, plastic and woven plastic materials. An example here is the new AD proFilm MP film valve sack, which is characterised by a particularly high level of moisture protection. Alongside the paper bag machine range of the W&H subsidiary Garant, W&H will present the bag machine range of the German company B&B Verpackungstechnik, for the manufacture of reclosable side-gusseted bags as well as stand-up pouches with inline spout insertion and optional leak detection.

Amut’s latest CPP line Italian machinery maker Amut has introduced one of its first cast film lines from the ACP series for the production of CPP film. The 2,100 mm-width line has been specifically designed for the production of film with embossed surfaces for stationery applications, such as folders for documents.

The chill roll group consists of main and secondary chill roll. In order to be able to produce both types of CPP film surfaces, the line is equipped with two different chill rolls. The roll changeover system enables the exchange of the main chill roll from one to another type in a short time, says Amut. It also has a four-layer multi manifold die with a depression air blade installed behind the extrusion die to change the position of the die towards chill roll as well as the film chill roll angle and to eliminate completely the orange-peel defect. The independent rotary arm type winder is equipped with an in-line cutting system for the production of finished rolls without any reduction of maximum winding diameter even when running multiple rolls in winding and with a minimum tail. US firms to present new technology at NPE Auto profile and related cooling systems for blown film lines supplier Addex Inc. will showcase its latest Intensive Cooling technology at the upcoming NPE 2018 show in May. The company will launch its “Height-Adjustable” intensive cooling twin-stack system, designed to optimise performance for both high and low-melt processes. Addex offers an enclosed, two-level, stacked, Intensive Cooling system featuring a lower Intensive Cooling element that mounts flat to the die and a second, height-adjustable Intensive Cooling element just below the air ring, which is adaptable to changes in materials and supports fast changeovers.
