What the materials cover

These materials come from a workshop on blown film extrusion that combines theoretical background with practical demonstrations. Practical problems and their solutions were first discussed in theory and then shown in the pilot plant of U.B.Tech. GmbH and in the laboratory. The first day covers the fundamentals: starting up different material types, centering the bubble and the frost line. On the second day, test specialists show how extrusion parameters affect film properties and briefly explain how the respective tests are carried out. The documents are particularly useful for new machine operators, commercial staff who want hands-on experience, and managers.
