Testarea COF a filmelor joac\u0103 un rol esen\u021bial \u00een evaluarea modului \u00een care se comport\u0103 filmele din plastic \u00een timpul proces\u0103rii, ambal\u0103rii \u0219i aplica\u021biilor de utilizare final\u0103. Produc\u0103torii, transformatorii \u0219i personalul de control al calit\u0103\u021bii se bazeaz\u0103 pe date precise de alunecare pentru a asigura buna func\u021bionare a liniilor de ambalare de mare vitez\u0103 \u0219i pentru a confirma consisten\u021ba produselor.

Ma\u0219inabilitatea acestora depinde \u00een mare m\u0103sur\u0103 de caracteristicile de frecare. Filmele cu frecare prea mare se pot bloca \u00een timpul prelucr\u0103rii, \u00een timp ce filmele cu frecare prea mic\u0103 pot aluneca necontrolat pe transportoare. Testarea COF a filmelor permite produc\u0103torilor s\u0103:<\/p>

  • Optimizarea performan\u021bei de procesare<\/p><\/li>
