PERPETUA LENIA

The mono PP laminate with isotropic tearing properties

PERPETUA LENIA is a mono PP laminate engineered for perfect tearability in transverse direction, it ensures easy, controlled opening while maintaining product integrity.

With improved seal strength, excellent hot-tack for lower sealing initiation temperature, and the ability to seal through contamination, it delivers reliability in demanding environments. Fully compliant with the European Pharmacopoeia, it offers high barrier protection and isotropic tearing properties—making it the ideal choice for safe and user-friendly pharma solutions.
