Candidates must be able to demonstrate existing knowledge levels through either passing the BFT2 end of course assessment or have achieved an NVQ Level 2 or completed our pre-course questionnaire and achieved a score of 70% or above.

Specifically designed to address the needs of people requiring high-level skills in configuring and optimising the blown film manufacturing process. In particular:

  • Setters
  • Process Engineers
  • Technicians and Multi-Skilled Engineers

On completion of the course the delegates will be able to:

  • Demonstrate an understanding of current safety legislation for the blown film process and the use of safe working practices
  • Describe the construction and operation on a blown film extruder, stating the function of component parts and process parameters
  • Demonstrate an understanding of blown film die construction principles and maintenance procedures
  • Identify various product sizing, cooling, folding and collection ancillary equipment designs
  • Describe the structure and properties of plastics materials and their interactions with the extruder
  • Identify relevant control and quality monitoring equipment and describe its usage
  • Set up and run a blown film line from a zero base situation
  • Undertake machine condition setting in a logical and systematic manner
  • Recognise common product faults and introduce appropriate rectification adjustments
  • Simulate a full product trial and maximise product quality and output rates
  • Shut-down a blown film line in a safe and efficient manner

Polymer Processing Certificate Part 3 Material covered has been aligned to the content of an NVQ at Level 3 and can be used as underpinning knowledge towards achieving the award, if so desired.

Individual candidate knowledge levels are assessed at the end of the training programme and a management report is provided to help identify further training requirements or career progression possibilities. This is a PTIC assessment of knowledge for the blown film process but candidates can then progress towards achievement of their PTIC Approved Technicians Award by successfully completing a further practical assessment
