Part 1: Plastics Materials and Technologies. Blown Film

Blown Film. A process known as blow film extrusion uses an industrial blower to expand a hot plastic tube into a light, strong plastic bag. The air inflates the plastic tube like a balloon until a bag with the desired shape, size, and wall thickness is formed. The balloon moves slowly up a tower, the bubble being contained by rollers that fold ...

Blown vs. Cast

Every formulation and manufacturers is a bit different, but some general rules of thumb apply. Blown stretch film tends to: be very resistant to puncture. have higher levels of "cling" (how the film 'sticks' to itself) make more noise unwinding. Cast stretch films often: are clearer & shinier on a load. unwind quieter.
