Die Introduced Drastically Reduces Purging Times

Macro Engineering & Technology Inc. introduces its latest coextrusion die for extruding high-barrier multilayer films. The new die for coextruding barrier films up to 11 layers can be used to produce structures using any barrier material including PA (Nylon), EVOH, PETG and PVdC. The optimized design of the FlatPack die, which features round flow channels throughout, streamlines the flow of polymer to optimize residence time distribution and shorten residence time. This reduced residence time virtually eliminates interfacial instability making the die more versatile for a wider range of film structures. The die also features shortened purging times, allowing processors to perform faster product changeovers with reduced scrap generation.
