Shrink and shrink force determine the quality and efficiency of shrink films. Incorrect shrinkage leads to material problems in deep drawing. The wrong shrink force leads to wrinkles or loss of productivity when shrinking films.
Optimizing the material formulation and process technology can help avoid complaints and bring about process stability.
One method for this is the heating of foil samples and the determination of the shrinkage curve by means of a video recording. The shrinkage force curve is determined using a force sensor. The data is then saved and visualized.
