Category: Blown Film Extrusion — Complete Training Program (P1–P9)

9 specialized courses. Built by engineers. For the people who actually run the lines.

Every blown film producer faces the same challenge: experienced operators retire, new ones make the same mistakes, and the gap between what your team knows and what your process demands keeps growing.

Meanwhile, a single unstable bubble, a wrong material decision, or a thickness deviation that goes unnoticed costs you thousands — not in theory, but on every shift where something is "not quite right" and nobody can explain why.

This is the training program that closes that gap.

What makes this program different from anything else on the market

This is not a generic plastics course. Every module was developed exclusively for blown film extrusion — by Dr. Magdalena Laabs, polymer engineer with hands-on experience in film production, troubleshooting, and process optimization across Europe and Latin America.

No other training provider offers a program this deep, this specialized, and fully available online.

The 9 courses — and what your team will be able to do after each one

P1 — Introduction to Blown Film Extrusion

Your team understands the process as a system — not a collection of random settings. They see how each stage affects the next, and they stop guessing.

P2 — Raw Materials, Rheology and Additives

Your operators know why the line behaves differently when you change material — before they change it, not after. Fewer surprises, fewer losses.

P3 — Construction of Blown Film Extrusion Lines

Your team understands how the extruder, die, cooling, and winding work together. When something goes wrong, they look for the cause — not just the symptom.

P4 — Process Optimization

This is where the real savings happen. Your team learns to diagnose common production problems, identify root causes, and take corrective action — fast and with confidence.

P5 — Supporting Technologies

Gravimetric dosing, thickness measurement, IBC, filtration — your team learns which technologies actually improve the process and which ones just add complexity.

P6 — Shrink and Stretch Hood Film Production

For producers of shrink film and stretch hoods: your team understands how process settings translate into end-use performance — shrinkage, load stability, and film strength.

P7 — Multilayer Film Technologies

Your team learns the logic behind 3- and 5-layer structures — which layer does what, how to design them, and how layer ratios affect film properties and process stability.

P8 — Films from Recycled Materials

Working with regrind and recyclate is not the same as working with virgin material. This course teaches your team how to maintain quality and stability despite variable input.

P9 — Economics and Cost Analysis

Your team sees the process through the lens of cost — material consumption, energy, scrap, downtime. Small improvements here translate directly into margin.

Who is this program for?

Machine operators who want to understand the process, not just follow instructions. Process engineers and technologists who need to optimize and troubleshoot. Quality managers who want to trace problems back to their real cause. Production managers and plant directors who need their team aligned. Companies onboarding new employees or commissioning new lines.

What you get

9 online courses, each with 4 weeks of access. Practical PDF materials — not theory slides, but production-focused content. Video and audio explanations for key topics. Checklists you can use directly on the production floor. Quiz and Rolbatch Academy certificate after each course. Learn at your own pace — individually or as a team.
