Coming soon – contact us to find out when your language version will be available
This course is designed for professionals in the plastics extrusion and recycling industry who work with washed and shredded LDPE, HDPE, or PP films. You’ll learn how to deal with variable material quality, set process parameters, and prevent defects in film-based regranulation.
Who is this course for?
🟢 For professionals experienced in plastic extrusion who work with recycled LDPE, HDPE or PP films.
🟢 For engineers, technologists, and production managers reprocessing film flakes from post-consumer or industrial sources.
🟢 For those seeking better quality control, higher process efficiency, and reduced material loss.
Course Objective
The goal of this course is to provide in-depth knowledge about regranulating polyolefin films. It focuses on flake-based regranulation, assuming the input material has already been washed and dried. Participants will learn how to adapt machine settings, analyze film quality, and improve production repeatability despite variations in recycled feedstock.
Why should you join?
🟢 Understand how flake characteristics influence regranulate quality and process stability.
🟢 Learn to recognize and prevent common issues such as burning, viscosity changes, and inconsistent granulation.
🟢 Discover how to optimize energy use and reduce material waste.
🟢 Master quality control at every stage of the regranulation process.
🟢 Gain practical tools to improve repeatability, reduce customer complaints, and stabilize daily operations.
What will you learn?
🟢 Properties of LDPE, HDPE, and PP film flakes
How to assess cleanliness, moisture level, and processability before extrusion.
🟢 Key process parameters in film regranulation:
• Correct dosing and plasticizing of film flakes
• Filtration techniques to handle contamination
• Granulation and cooling settings for consistent pellet formation
🟢 Practical troubleshooting in extrusion of recycled films:
• Eliminating burnt material and flow instability
• Improving thermal and dimensional stability
• Preventing off-spec batches and customer complaints
🟢 Process optimization and automation strategies:
• Boosting line efficiency without compromising quality
• Reducing energy consumption and extending equipment life
• Real-time monitoring of MFI, moisture, and density
