How do raw material properties affect film quality?
📚 This is the second course in the blown film extrusion training series. In this part, we focus on the characteristics of raw materials and additives used in PE film production, their impact on product quality, and the methods for selecting optimal materials for various applications.
Raw material is the foundation of the process – its properties are crucial for strength, flexibility, transparency, and further processing of the film. In this course, you will learn how to assess raw material quality, which modifying additives to use, and how to manage regranulates to maintain process stability.
🎯 Who is this course for?
✅ For machine operators who want to understand how raw material properties affect production process stability.
✅ For process engineers involved in optimizing extrusion parameters and selecting the best materials.
✅ For quality control specialists who inspect raw materials and want to know how their properties influence the final product.
✅ For production managers looking to reduce costs through the optimization of raw materials and additives.
🎯 Course Objective
The goal of this course is to provide in-depth knowledge about the properties of raw materials used in PE film production and how to efficiently utilize them in the extrusion process.
Participants will learn:
🔹 What are the properties of different types of polyethylene used in PE film production?
🔹 How do modifying additives like UV stabilizers, antiblocks, and slip agents work?
🔹 How to manage the quality of raw materials and regranulates to ensure stable production?
After completing this course, participants will be able to select the right raw materials and additives for specific film applications and minimize the risk of defects caused by material quality.
Why should you take this course?
✔️ Learn the key properties of LDPE, MDPE, LLDPE, and HDPE and their impact on film parameters.
✔️ Understand how modifying additives affect film properties and how to determine the right amounts.
✔️ Master raw material quality management to reduce waste and ensure process stability.
✔️ Learn how to choose raw materials for different types of films – from packaging to technical applications.
