Thermoshrinkable films
Created Friday, 07 September 2018The thermoshrinkable films shrink under the effect of heat because during their implementation stresses imposed on the film are abruptly frozen. These are oriented polymer films that, when reheated, release the accumulated stresses. The phenomenon takes place in three stages : the film enters the oven: thermal expansion during heating ; the film reaches Tsoftening: the internal tensions are r...
