The food packaging industry is under increasing pressure to reduce material consumption while maintaining product protection, shelf life, and visual appeal. As sustainability becomes a key driver, converters and brand owners are looking for solutions that combine performance with significant material savings.
From Conventional Laminates to Next-Generation Coextrusion
Traditional top lidding films are typically produced by laminating multiple film layers, resulting in structures of approximately 45 µm. While effective, these constructions require additional processing steps and increase material usage.
Today, advances in coextrusion and film orientation technology are changing the game. High-barrier PE/PA/EVOH lidding films can now be produced in a single manufacturing process with a total thickness of only 25 µm, eliminating the need for complex lamination while delivering outstanding packaging performance.
Triple Bubble® Technology Makes the Difference
At the heart of this innovation lies KUHNE's Triple Bubble® technology.
Through precise biaxial orientation and advanced process control, the technology optimizes molecular alignment within the film structure. The result is an ultra-thin film combining excellent mechanical strength, dimensional stability, optical quality, and barrier performance.
Maximum Performance, Minimum Material
Despite its reduced thickness, the film delivers performance traditionally associated with much thicker laminated structures.
Key benefits include:
- Excellent oxygen barrier protection
- High stiffness and toughness
- Outstanding transparency and gloss
- Reliable sealing performance
- Excellent thermal and mechanical resistance
- Integrated anti-fog functionality
The result is a premium lidding film that protects sensitive food products while enhancing shelf presentation and consumer appeal.
Designed for Demanding Food Packaging Applications
The film is ideally suited for applications such as:
- Poultry
- Fresh and processed meat
- Fish and seafood
- Fresh pasta
- Ready meals
Used as a tray lidding film, it helps preserve freshness by limiting oxygen ingress while maintaining exceptional clarity and package appearance.
Sustainability Through Downgauging
Reducing film thickness from approximately 45 µm to just 25 µm delivers significant sustainability benefits.
Manufacturers can reduce raw material consumption, lower packaging weight, improve transportation efficiency, and decrease logistics costs while maintaining packaging performance.
This combination of downgauging and high functionality represents an important step toward more sustainable food packaging solutions.
The Future of High-Barrier Lidding Films
By combining ultra-thin structures with superior barrier properties, excellent optics, and outstanding mechanical performance, Triple Bubble® technology is setting new standards in flexible packaging.
As demand for sustainable and resource-efficient packaging continues to grow, 25 µm coextruded lidding films offer an attractive solution for manufacturers seeking to reduce material usage without compromising performance.
