# Recyclable Packaging Films RATTPACK's murFlEX Simplifies Its Mono-Polypropylene Packaging By Adam Harrie | Written with AI assistance | Published 2026-04-23 | Art & Design Source: Trend Hunter, https://www.trendhunter.com/trends/Mono-Polypropylene References: [packagingeurope](https://packagingeurope.com/news/mono-pp-high-barrier-clip-foil-developed-by-rattpack-for-retort-applications/14128.article)  RATTPACK introduced murFLEX PP Clip Foil, a recyclable, [mono-polypropylene high-barrier film](https://www.trendhunter.com/trends/Polypropylene-Snack) designed for retort applications, featuring a multilayer structure made entirely from PP. The film targets flow packs, stand-up pouches and lidding films, offering heat-stable sealing and improved oxygen and moisture resistance for sterilized food packaging. murFLEX was developed to replace mixed-material laminates with a [single-polymer solution](https://www.trendhunter.com/trends/mdope-pouch), combining barrier coatings and clip-foil construction to maintain performance during retort processing. The material supports conventional pouch and lid formats and is compatible with existing heat-sealing equipment. For brands and manufacturers, murFLEX promises easier recycling streams and lower complexity in end-of-life sorting while preserving shelf-stable performance, aligning with [circular packaging trends](https://www.trendhunter.com/trends/Future-ready-recycled-packaging). Its single-polymer approach reduces multilayer waste without altering consumer-facing packaging formats.
