Cast Extruded Film Inspection

EasyInspect for cast extruded film inspection identifies defects and irregularities that can occur at any step of cast extrusion film production by inspecting after each value-adding process step, e.g. after chill roll or after MDO coating, depending on the film's final use.

EasyMeasure helps to control the coating process by monitoring physical properties such as layer thickness, porosity, reflectivity and haze.

Together they allow full control over the extrusion, laminating and finishing processes and through this over the quality of the end product.

EasyInspect for cast extruded film inspection is used for local defect detection, for example in:

  • Gels / fish eye defect detection
  • Pin hole defect detection
  • Black spots / white spots
  • Scratch defect detection
  • Die line defect / streak defect detection
  • Melt line defect detection
  • Z fold defect detection
Cast extruded film inspection

This helps cast extruded film manufacturers and converters inspect the base material, for example polycarbonate, and subsequent converting steps. EasyInspect  performs stretching inspection, coating inspection, sputtering and laminating inspection. At the end of the line, prior to the winder and the automatic roll-cutting system, EasyInspect continuously identifies a variety of defects and feeds this quality information back to each of the different production steps.

Typical tasks for EasyInspect & EasyMeasure for cast extruded film inspection include:

  • CPP white film, transparent film or metallized film inspection for use in e.g. packaging, bakery or confectionary wraps, twist and metallized twist wraps, anti-fog film for fruit or vegetable packing and many more
  • High barrier film inspection with or without shrink for use in e.g. flow-packs, bags, lidding films, etc.
  • Sophisticated multi-layer film inspection for use in manifold safe and economic product packaging

EasyInspect & EasyMeasure for cast extruded film inspection use Dr. Schenk’s unique MIDA Technology to inspect cast extruded film base and converted materials with multiple optical channels on a single scan line. One defect generates multiple images to deliver the most comprehensive material analysis and defect classification on the market.
