Why Do You Need Bubble Cages?

Blown film extrusion is the process that involves extruding a tube of molten polymer through a Blown Film Die (Single or Multi-Layer), which is a vertical cylinder with a circular opening. Air is injected through a hole in the center of the die creating a bubble, several times its initial diameter. The bubble is pulled upwards and an Air Ring blows air onto the film to cool.


Bubble cages reduce the turbulence caused by the cooling air stream when it hits the bubble. The Bubble Cage reduces movement that the bubble would otherwise have and prevents the bubble from losing stability. More stability results in increased production as well as improved quality.
