Question

What will be an ideal response?

Answer 1

The desired material is extruded through a die creating a tube of melted resin. At the center of this tube is an air nozzle that inflates the extrudate out to the sizing basket. The sizing basket helps to contain the blown film along with the regulation of the air pressure. Once the material has cooled to an appropriate temperature it runs through collapsing guides that help to fold the blown film in preparation for labeling, sealing and trimming. After the collapsing guides, the film goes through the nip rollers that remove as much air as possible. The film then goes through whatever processes are necessary for that particular film; these processes may include perforation, labeling,

sealing or slitting. After this post process the film is generally rolled onto a take-up roll and shipped to customers.
