Rewinder description Afex

In a blown film extruder PE granulates (or other polymer)
are melted in an extruder and pushed through a circular die extruding
a tube of molten polymer.
Tube is then inflated to multiples of its initial diameter and cooled to
form a thin film. Bobble is later collapsed and re-winded.
