    Przedstawiono wyniki bada艅 dotycz膮ce wp艂ywu czasu sezonowania na wybrane w艂a艣ciwo艣ci folii polipropylenowej orientowanej dwuosiowo. Pr贸bki folii pobrane z dw贸ch r贸偶nych partii produkcyjnych, odznacza艂y si臋 tym samym sk艂adem recepturowym i grubo艣ci膮. Pr贸bki by艂y przechowywane w warunkach magazynowych. W艂a艣ciwo艣ci optyczne i mechaniczne folii oznaczono bezpo艣rednio po jej wyprodukowaniu oraz po 3, 14, 28 i 56 dobach sezonowania.The results of studies of the effect of seasoning time on the select properties of biaxal oriented polypropylene film were presented. The films samples, characterized by the same prescription compositions and thickness were taken from two different production batch. The samples were stored in a warehouse conditions. Optical and mechanical properties of films were determined directly after their production and after 3, 14, 28 and 56 seasoning days. The effect of seasoning time of films in a warehouse conditions on their properties was evaluated
