Plastic film and sheet extrusion systems supplier Macro Engineering & Technology Inc. is introducing its latest coextrusion die for extruding high barrier multilayer films at K.
The new die for coextruding barrier films up to 11 layers can reportedly be used to produce structures using any barrier material including PA (Nylon), EVOH, PETG and PVdC. The design of the FlatPack die, which features round flow channels throughout, has been engineered to streamline the flow of polymer, optimising distribution and shortenening residence time. Macro claims that this “virtually eliminates” interfacial instability making the die versatile for a range of film structures. The die also features shortened purging times, allowing processors to perform faster product changeovers with reduced scrap generation.
“Over the past year we have revamped our extrusion die department”, said Jim Stobie, CEO at Macro. “Our objective is to provide more versatile extrusion dies to flexible film producers; dies that allow users to manufacture a broader range of products while being more reliable and with less down time. We’ve invested in our rheology and engineering personnel to drive that innovation. We’ve refocused our blown film die offering; upgraded our CenterPack die, and are excited to launch our new FlatPack die”.
A 9-layer FlatPack configuration has reportedly been shown to reduce residence time up to 30% and shorten purging time by 20%. The FlatPack also gives processors the added flexibility to allow major film structure adjustments by swapping layers, such as reconfiguring a A/B/C/D/E structure to A/C/D/B/E. Macro will be located in Hall 16 at Stand B06.
