Reliable solutions for demanding film extrusion processes
Film extrusion processes place extremely high demands on material quality, web alignment, accuracy and stability. Even minor deviations can lead to serious defects such as burns, gels, wrinkles, baggy edges, or tension issues – resulting in scrap, downtime and reduced productivity.
BST supports film extrusion manufacturers with precise web guiding and surface inspection solutions. By combining decades of experience in web processing with advanced guiding and inspection technologies, our systems enable early detection of deviations, stabilize critical processes and maintain tight tolerances across a wide range of extrusion applications.
The result is consistently high product quality, improved process reliability and reduced waste – even under demanding production conditions.
BST solutions across film extrusion processes
Blown film extrusion
After cooling, the film is guided securely as a web – ensuring a stable process and reproducible quality. With SMART Guide, the material remains precisely in position, even under changing conditions. In addition, iPQ-Surface detects surface defects in the substrates, before they move on to further processing.
Flat film extrusion
Flat films often represent the highest quality standards, which makes consistent, objective inline inspection the most important task. iPQ-Surface reliably detects defects in real time and helps to reduce waste.
Extrusion coating and lamination
iPQ-Surface ensures quality by detecting coating defects, inhomogeneities, or surface irregularities at an early stage. Precise web stability is crucial during coating and laminating to ensure that layers are bonded permanently and cleanly. In addition Register control supports precise alignment when multiple layers or functional structures need to run synchronously.
