Blog over 60m MOPP Film Advances Singlematerial Circular Packaging

The packaging industry faces mounting pressure to balance consumer convenience with environmental responsibility. A groundbreaking solution has emerged that addresses both challenges simultaneously: the 60μm MOPP (Monoaxially Oriented Polypropylene) easy-tear film.

This specialized material for flexible packaging, particularly stand-up pouches, combines easy-tear functionality with exceptional toughness and superior sealing performance. The film's unique linear tear characteristic, achieved through in-line monoaxial orientation, transfers effectively to the entire laminated package structure, enabling clean, effortless opening without the frustration of traditional packaging.

Composed entirely of polypropylene (PP), the 60μm MOPP film presents an ideal solution for packaging recyclability. Its single-material design simplifies recycling processes and improves efficiency, supporting closed-loop circular economy systems. The manufacturing process incorporates high percentages of in-line recycled production waste, further reducing environmental impact while maintaining economic viability.

• Optimized tear-resistance balance: Precise in-line monoaxial orientation (MDO) maintains high strength and sealing performance while enabling controlled linear tearing.
• Superior lamination compatibility: Tear characteristics transfer effectively to other substrate layers in composite packaging.
• 100% PP composition: Simplifies recycling processes in alignment with circular economy principles.
• High recycled content integration: Manufacturing incorporates significant percentages of recycled production waste.
• Exceptional flatness and uniformity: Ensures high downstream processing efficiency and stability with minimal waste.

The 60μm MOPP film utilizes multilayer coextrusion technology with carefully engineered resin formulations:

• 48μm main layer: Borealis RD208CF RCPP resin provides mechanical strength and lamination performance.
• 6μm intermediate layer: Borealis BB213CF HeCoPP resin enhances overall toughness.
• 6μm sealing layer: Borealis BB213CF HeCoPP resin ensures packaging integrity.
• Additives: Includes 20% antiblock masterbatch for smooth processing.

The FILMEX cast film production line with integrated MDO L (in-line monoaxial orientation) unit enables the film's exceptional performance characteristics. This advanced system represents global leadership in cast film technology.

• Production rates up to 1,200 kg/h with MDO line speeds reaching 300 m/min
• Automatic gap adjustment ensures process stability and minimizes neck-in
• P-MDO control system maintains consistent film profile
• FILMATIC TC winding technology ensures superior roll quality
• Capable of producing 5-7 layer films (20-100μm) for various applications

This technological advancement represents a significant step forward in sustainable packaging solutions, offering manufacturers an opportunity to enhance product value while reducing environmental impact.
