BOPP Cigarette Packaging Coefficient of Friction

July 15, 2009 - PRLog -- The smoothness of BOPP cigarette film is one important index for BOPP films with is the testing requirements coming along with the high speed packing.
 There are four kinds of situations that need coefficient of friction testing, namely, the coefficient of friction of the film and the metal side of the machine or the transfer belt; the inside side between films; the film inner side and the cigarette outer package; and the outer film side and the outer package. Of these four coefficients of friction, the first should be low so as to better transfer the cigarette package and improve packing speed. The inside coefficient of friction should be a bit higher than that of the outer film and the machine metal side for precise location of film and cigarette package so as to improve heat seal quality and packing effects. The coefficient of film and outer paper box should be low for smooth insertion of cigarette packages. The testing speed is 100mm/min, or 150mm/min in US Standard. Labthink PARAM MXD-02 Coefficient of Friction Tester complies with many standards including US standards and international standards, and gets wide applications. Since the reference for cigarette film coefficient of friction varies, e.g., metal panel, cigarette box, inner and outer sides of films, etc., the coefficient of friction is normally between 0.2-0.6.
