RESUMO

The present paper studies the effects of the additions between 3.00 and 7.00 wt% of additive Granic 422 instead of polypropylene on polymeric tapes properties as color difference, structure and tensile parameters. Micro-structural analysis revealed additional agglomerations of calcium carbonate particles on the surfaces of the tapes after application of new portions of the variable additive. Composition-property relations showing the changes in properties of tapes were suggested. For increase in color difference of the tapes from zero to 0.18, a logarithmic relation was used. For other indices, the linear relations were proposed. On the basis of the relations, the positive changes of 2.0-2.7% in macro-structural parameters (width, thickness, linear density) and negative changes of 2.1-8.8% in tensile characteristics were obtained.
