Improve stiffness and elongation at break in BOPP films

Improved stiffness with Oppera

Many end-users, particularly for overwrap applications, look for a bi-oriented polypropylene (BOPP) film with outstanding stiffness that also processes without wrinkling.

Oppera modifier in BOPP film formulations provides an overall improvement of mechanical properties, including film stiffness and elongation at break. These benefits allow the production of a downgauged or thinner film to run smoothly for greater efficiency.
