Most polyolefins exhibit a degree of ‘tackiness’ which cannot
readily be processed into packaging films without the presence of special additives.
Many current polyolefin film formulations contain fatty acid amides (slip agents)
and inorganic materials (antiblock agents) to reduce friction resistance and lower
film-to-film adhesion, respectively. This study demonstrates that it is possible to
optimize slip and antiblock additives in order to obtain desirable friction and
blocking force while maintaining a good printability.
