Oppera™ modifier allow precise tailoring of bi-oriented polypropylene (BOPP) film performance in applications such as shrink packaging that benefit from high-shrink capabilities.
Testing demonstrates machine direction shrinkage can be increased significantly with the use of 7.5% Oppera modifier. This shrinkage can be especially valuable in the shrink packaging of bulk goods and also for tight overwrap of medicines, cosmetics, tea and tobacco packaging where the overwrapped film must tightly conform to the product or shipping unit.
