Recorded Wednesday, October 25 – Presented by Dow Performance Silicones
Eliminating migration enables higher productivity, superior printing and more
A 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.
Controlling the COF
Coefficient of friction (COF) is a recurrent problem in BOPP film packaging production because it can negatively affect the film’s appearance, cause deformations and even rupture, which interrupts throughput. Traditional slip agents cannot guarantee a constant COF.
Also, standard COF reduction agents continuously migrate to the film surface. Migration is a big problem that can:
• Increase the haze level of clear film
• Negatively affect downstream printing, lamination and metallization
To 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.
New masterbatch offers major benefits:
• Immediately lowers the COF for BOPP films
• Prevents transfer to the corona-treated face to preserve printability and lamination and metallization capability
• Remains stable over time and temperature for permanent slip performance
• Will not significantly affect optical qualities of the film
The Dow webinar will describe the challenges of optimizing slip performance in BOPP film production – using both sequential and simultaneous stretching lines – and showcase the advantages of new-generation silicone technology. Topics will include:
• Common challenges faced by film processors
• Product test data on COF and haze performance, and effect on surface tension of corona-treated film
• Technical guidance on using the new masterbatch
