About the Seminar
This three-day program provides a broad overview of blown film extrusion, including materials,
hardware, and processing methods. In addition to the classroom sessions, there will be hands-on
workshops each day. Upon completion of this seminar, attendees will be able to:
- describe how all parts of an extrusion line interact with plastic material to affect final product performance and quality
- identify various polymer materials used to produce blown film and discuss important film properties
- discuss in detail the hardware specific to blown film processing, including screws and dies
- describe how bubble geometry creates the molecular structure that influences film properties
- troubleshoot both extruder and film problems
- operate a laboratory three-layer blown film line
What the attendees will learn
- hardware systems on an extruder and the functions that the extruder performs on the plastic material
- various polymers used to produce blown film, including the rheological and solid state properties of these polymeric materials
- upstream and downstream hardware specific to blown film extrusion
- bubble geometry and the process parameters used to create specific bubble shapes
- control systems, both manual and automated, for maintaining product targets
- process/structure/property relationships in blown film: how bubble geometry affects molecular structure and film properties
- basic blown film coextrusion principles
- how to solve both extruder and film problems
Who should attend
- Operators
- Set-up technicians
- Process engineers
- Quality control personnel
- Floor supervisors
- Plant managers
- Film purchasers
