Macro Engineering redesigns coextrusion die for blown film systems

Macro Engineering & Technology has redesigned its CenterPack coextrusion die for blown film systems, in a bid to improve processing versatility, and minimize residence time.

The Canadian plastic film and sheet extrusion systems supplier improved the die’s layer ratio range by more than 25% and purging time by 40-50%.

Following the upgrades, the new CenterPack die can process blown as well as cast film grade resins without any issues relating to interlayer clarity.

The redesigned CenterPack die is available to process film structures up to nine layers and in die diameters up to 2m. It provides film quality for Nylon 6, EVOH, PP, PETG, plastomers, LLDP for laminating and thermoforming applications.

According to the company, the die is a stackable design using a center-fed system that guarantees low residence time, fast purging and delivers flat film with gauge that is better than ± 5% (2-sigma).

Macro Engineering supplies film and sheet extrusion systems and specializes in barrier film lines and custom engineered extrusion systems.
