Eliminating migration enables higher productivity, superior printing and more<\/strong>
\nA new, non-migrating silicone masterbatch for processing bi-axially oriented polypropylene (BOPP) film delivers stable, long-term slip performance without the drawbacks of standard slip agents such as organic waxes and silicone oil.<\/p>\n

Controlling the COF<\/strong>
\nCoefficient of friction (COF) is a recurrent problem in BOPP film packaging production because it can negatively affect the film\u2019s appearance, cause deformations and even rupture, which interrupts throughput. Traditional slip agents cannot guarantee a constant COF.
\nAlso, standard COF reduction agents continuously migrate to the film surface. Migration is a big problem that can:
\n\u2022 Increase the haze level of clear film
\n\u2022 Negatively affect downstream printing, lamination and metallization
\nTo solve these issues, Dow has developed a patent-pending, silicone-based masterbatch for BOPP and cast films used mainly in food bags, wrappers, packages and pouches.<\/p>\n

New masterbatch offers major benefits:<\/strong>
\n\u2022 Immediately lowers the COF for BOPP films
\n\u2022 Prevents transfer to the corona-treated face to preserve printability and lamination and metallization capability
\n\u2022 Remains stable over time and temperature for permanent slip performance
\n\u2022 Will not significantly affect optical qualities of the film<\/p>\n

The Dow webinar will describe the challenges of optimizing slip performance in BOPP film production \u2013 using both sequential and simultaneous stretching lines \u2013 and showcase the advantages of new-generation silicone technology. Topics will include:
\n\u2022 Common challenges faced by film processors
\n\u2022 Product test data on COF and haze performance, and effect on surface tension of corona-treated film
\n\u2022 Technical guidance on using the new masterbatch<\/p>\n
