Compostable transparent film for the food and industrial packaging

A sustainable solution for cling film used in fresh-food packaging has been developed by Basf and Fabbri Group. Based on Basf’s certified compostable ecovio, Fabbri Group produces the highly transparent stretch film Nature Fresh. Meat, seafood as well as fruit and vegetables can be wrapped manually or with automatic packaging equipment. Industrial stretch packaging is also possible. It is the first certified compostable cling film that combines optimal breathability for an extended shelf life of fresh food with high transparency and excellent mechanical properties for automatic packaging. Nature Fresh is food-contact approved according to US and European standards.


With this property profile, the film helps to keep food fresh for a longer period of time when compared to PVC alternatives used for cling film such as PE. As a consequence, the greenhouse gas emissions originating from food that is produced and distributed - but ultimately wasted - can be reduced. After usage Nature Fresh can be composted together with any food waste in home compost or industrial compost according to national legislation. It thus enables organic recycling and helps closing the nutrient loop towards a circular economy.


Cling or stretch film is a flexible thin film that is predominately used for packaging and applied in a stretch-wrap process. Wrapping can be done manually or by machines. The Nature Fresh film made of ecovio is the certified compostable alternative to cling films made of PVC and PE so far used in fresh food packaging: its overall performance - mechanical properties like tensile strength and elongation at break, breathability, film transparency and aesthetics like elastic recovery and anti-fogging - is comparable to films made of PVC. At the same time ecovio shows a better water vapor transmission than PE, which is essential for optimal fresh food packaging.


In order to find the perfect match of a sustainable material with excellent packaging properties and easy wrapping, Basf and Fabbri Group joined to develop a cling film which can also be efficiently used on stretch wrapping machines. Fabbri Group offers Nature Fresh in four different formats: as rolls for manual or automatic packaging machines in industrial food packaging, for cutter boxes in hotels, restaurants and catering services, as jumbo rolls for converters as well as rolls for end consumer hand-wrapping applications.
