Packaging material performance requirements --The friction factor

Friction factor is the measure index of packaging material sliding characteristics, surface smooth thin film materials for food automatic filling production line is very important, different USES of packaging materials have different requirements on friction factor. Friction is not only the production line of the drag force and resistance, therefore must effectively control the size of the film friction factor, to make it in the proper range. In order to adapt to the need of automatic packaging production line, generally need to the friction factor of flexible packaging materials need to adjust to o. 2 ~ o. 3.

stand up bag
Automatic packaging coil, general requirements lining friction coefficient is small, and the outer friction factor is moderate; But the inner friction factor and not too small, otherwise may cause bag molding material is not stable and produce the wrong side, Too much outer friction factor can cause resistance in the process of packaging is too big, cause the tensile deformation, too small may cause drag institutions skid cause electric eye tracking and cut off the location is not allowed.
