Abstract: The Intervals (zones) with different shrinkage are formed in thermoplastic polymer films by the local modification of their structure on the defined material zones; they are specific “watermarks” which are invisible under the layer of printing ink. By printing of the information marks, which are consisting of thin lines, on the film is manufactured a product (brand mark, label etc.); the authenticity of this product can be tested by temperature increase up to the defined grade, which provides a heterogeneous shrinkage of polymer film. The heating of interval shrinkable film at strongly controlled conditions is a basis for the showing up of latent and tactile marks. The dilatometric and calorimetric studies allow the estimating of the optimal value of shrinkage and effect of "shape memory" on various interval films.
