MarinaTex Window Film

Plastic-free, compostable film that replaces PET and OPS windows in premium packaging. Clarity without the plastic.

A plastic-free film that brings clarity to premium packaging without the plastic.

The window is where premium packaging usually breaks its own sustainability promise. Show the product and you add a PET or OPS window that contaminates the pack at end-of-life; hide it and you lose the moment of desire on shelf. Our natural polymer film removes that trade-off. It is transparent, flexible and strong, replacing the PET flexible-film windows and OPS rigid windows used across cartons, sleeves and premium packaging, and keeping the visibility and premium feel a brand depends on.

It is plastic-free and compostable, validated in our own testing, and designed to return safely at end-of-life rather than persist as microplastic. Recyclability is under assessment as we complete independent validation, so we are clear about what is proven today and what is still being confirmed.

Where it stands: the film's barrier and shelf-life performance are proven in the lab across selected formats. The manufacturing route is still in development, and we are working through how to produce the film at commercial scale. We are partnering with brand owners and converters who want to design plastic out of their premium windows early, and to help shape the formats and specifications we bring to market.
