Temperatures above 200 °C (392 °F) or prolonged exposure to temperatures above 190 °C (374°F) can result in considerable polymer degradation. Compression Ratio of 2.0 - 2.5 with a metering channel depth of about 9-11% of the barrel diameter is recommended.

Blown Film Processing Equipment A spiral mandrel die is recommended for blown film processing. The die-gap for blown film processing of B5011 should be in the range of 1.0-1.6 mm (40-65 mils). B5011 can be processed successfully on blown film lines equipped to operate in the traditional “low stalk” bubble configuration mode with a dual-lip air ring. Chilled air supply for the air ring will facilitate a more stable bubble at higher line speeds.
A BUR of 2.5 to 3.5 and draw down ratio (DDR) of <25 is recommended.
The film can be processed on lines with or without the use of internal bubble cooling.
