Rigid vinyl: Resilience™ HC formulations provide field-tested, exceptional, chemical resistance across a range of disinfectant chemistries, combined with excellent melt flow, flame and UV resistance and attractive appearance.  Media contact: Media Relations Contacts

This shift is improving access to PCR for closures specifically and, as a result, increasing the amount of PCR used across all plastic packaging, including in more challenging situations such as food-contact packaging. Additives, such as melt flow modifiers, can be used to recover the loss of physical properties and aesthetics when applying PCR resins Contact us if you would like to learn more, or talk with one of our product experts about your own PCR challenges.
