Blown Film Inspection

EasyInspect for blown film inspection identifies miniscule defects that can occur during the manufacturing process. EasyMeasure monitors the homogeneity of the final product’s properties. The combination with EasyInspect for blown film inspection ensures product quality and optimizes the blown film manufacturing process with just one system.

This technology helps blown film manufacturers and converters to combine the detection of defects with material monitoring. For the first time, EasyMeasure enables the classification of the product quality’s functional level within defect-free material.

EasyInspect for blown film is used for local defect detection, e.g. for:

Gels / fish eye detection
Air bubble detection
Die-line detection
Weld-line detection
MD scratch detection
Carbon speck detection
Insect detection
Tear detection
Melt fracture detection
Wrinkle detection (MD and diagonal)

EasyInspect & EasyMeasure for blown film inspection use Dr. Schenk’s unique MIDA Technology to inspect blown 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 on the market.

Typical blown film applications and EasyInspect/EasyMeasure tasks include:

Base material inspection for converted products
Agricultural film inspection
Bags inspection
Barrier film inspection
Laminated film inspection
Packaging film inspection, food wrapping inspection

EasyMeasure continuously monitors the overall physical properties of the blown film. For example clarity and haze monitor the non-homogeneous mixture of the granulate with the master batch;gloss and reflectance control surface distortions like applesauce, orange peel and shark caused by bad resin, die lip issues or melt fracture among others.
