摘要

Nowadays web inspection systems are more and more an integrated part of extrusion and converting/laminating lines. On the one hand the customer demands a 100% quality control (pharma, medical, food, technical films etc.), on the other hand the film producers and converters need to avoid scrap and optimise their production process.But no ISO or DIN standard for the definition of defects like gels and no rules for the definition of scrap exists. Every plastic film consists of contaminations, which come from the production process or are a part of the nature of Polymers. Thus gels are only a question of resolution.In Polymer plants an online quality control and lot grading via gel count is done as a standard within each raw material producer for many years.The definition of defects in extrusion and converting lines distinguish types like gels, black specs, fish eyes, holes, oil stains, insects, scratches, coating voids, air bubbles etc. These defect types have different causes of origin and impact on the further processing.A close interrelationship and discussion between the raw material suppliers, the extrusion/converting companies and the end customer is becoming more and more crucial to succeed within the market and to achieve a competitive advantage.
