Tehnic, m\u0103soar\u0103 presiunea maxim\u0103 pe care o poate suporta h\u00e2rtia \u00eenainte de a se rupe. Acest lucru este deosebit de important pentru:<\/p>\n\n\n\n

        La GreenWing, fiecare lot de produc\u021bie trece prin controlul intern al calit\u0103\u021bii. Pentru rezisten\u021ba la spargere, \u00eendoire \u0219i rupere, folosim ma\u0219ini de laborator - nu doar observa\u021bii \u0219i presupuneri.<\/p>\n\n\n\n

          Oamenii presupun adesea c\u0103 o h\u00e2rtie mai groas\u0103 = o pung\u0103 mai rezistent\u0103.<\/p>\n\n\n\n

          Rezisten\u021ba la spargere, \u00eendoire \u0219i rupere depinde de mai multe variabile:<\/p>\n\n\n\n
