PFAS-Free Processing Aid for Blown Film Extrusion

Ampacet has introduced a PFAS-free polymer processing aid (PPA) masterbatch that is said to perform as well as fluoro-based PPAs in blown film extrusion for multiple end-use applications. Due to potential health hazards perfluoroalkyl and polyfluoroalkyl substances (PFAS) have been regulated in food packaging by several states, with.additional governmental restrictions  expected this year and beyond.

PFAS have been used in polymer process aids for years in dozens of product categories. According to Ampacet, its line of PFAS-Free PPA, a synergistic blend of chemistries designed to be roughly equivalent to the performance of a commonly used fluoro-based PPAs.

Depending on the user’s process, 1% to 3% of Ampacet PFAS-Free PPA masterbatch is generally required. The new PPA is FDA food contact compliant, with comparable economics to PFAS. Other benefits cited include:

  ▪  Eliminates melt fracture

  ▪  Reduces die build up

 ▪  Productivity gains (increased throughput)

 ▪  Reduced plastic waste supports sustainability goals

 ▪  No interference with surface treatment (printing and laminating)

 ▪  No effect on sealing
