better sealing quality in FFS machines. The company will also present its Evolution Ultra
Stretch technology – which was presented at K2013 as a prototype system. The system allows an easy way of downgauging with
equivalent or better film properties for numerous applications: compression bag film can be made around 30% thinner, such as reducing diaper packaging from 70 to 50 microns; pre-stretched silage stretch film can be made at least 25% thinner; and breathable back- sheet film made on this equipment requires lower investment than film produced using conventional in-line MDO, claims Reifenhäuser. At the same time, the company will show the
Evolution Ultra Die – its new barrier blown film die head design. A combination of stack die design and spiral mandrel distribution design results in high flexibility in terms of layer ratios and viscosities in barrier film production.
Flat die advances
Nordson EDI has redesigned its Autoflex VI flat extrusion die to increase the stroke of the lip adjusting system by 43% – without adding to response time. This enables it to correct a wider range of process variations, often without need for manual intervention, said the company – which will introduce the new system at K2016. The new Autoflex VI-E lip
adjusting system is smaller and more streamlined, simplifying
disassembly and reducing the time for maintenance. “We redesigned the
Autoflex VI system in response to feedback from customers, who told us their greatest needs were for increased automation and reduced downtime,” said Sam Iuliano, business development manager for polymer dies at Nordson EDI. “Its greater responsiveness will be particularly valuable in thin-gauge applications such as cast film and extrusion coating.” Key aspects of the
redesign to streamline the system and make it more compact include: making all lip-adjustment
Nordson EDI says that its new Autoflex VI-E lip adjusting system is smaller and more streamlined than before
components accessible from the top or rear of the Autoflex unit; eliminating exposed electrical leads by routing the wires from each adjuster segment directly to a junction box; and, eliminating multiple components that previously needed to be removed for disassembly. Cloeren is to showcase its

latest Edge Bead Reduction die for extrusion coating applications – the EBR V – at K2016. With an installed base of over 50 EBR V dies, Cloeren says it has shown increased robustness compared to competitive products. EBR dies are used in extrusion coating and lamination, where change of deckle width flexible
Flow channels are about 70% shorter compared to
known die head designs, says the company – which leads to shorter job change time for symmetric or asymmetric barrier structures. Because there is less volume, and a smaller die head diameter and heating from the inside and outside, this leads to shorter heating-up times for start-up of the line and change of raw materials.

exhibit what it says is the world’s widest NanoLayer system, comprising a 55-layer NanoLayer feedblock paired with a 5,435mm Epoch die, to produce G3 NanoLayer stretch films – which Cloeren says show enhanced packaging integrity com- pared to previous versions.
