Innovia Films has launched its first range of ‘breathable’ biaxially oriented polypropylene (BOPP) film, PropaFresh P2G and P2GAF.
This range of specific permeable, non-perforated films is the direct result of work carried out at Innovia Films’ own research and development facility.
It means that the company can now tailor the rate at which gases – oxygen and carbon dioxide – are able to migrate in and out of a pack through the film itself.
The ability of PropaFresh P2G to ‘breathe’ makes this new film ideal for extending the shelf-life of a range of prepared fresh produce. This presents a unique challenge as fresh produce continues to respire following harvesting, processing and packing.
In addition to the new polymer formulation of PropaFresh P2G, a sister film PropaFresh P2GAF, has been developed, which provides excellent anti-mist properties.
The feature of PropaFresh P2G is that it has an oxygen permeability of 3000cm³/m² per 24hrs and a carbon dioxide permeability of 12000cm³/m² per 24hrs. This ratio is sustained, whilst still increasing the volume gas exchange. The products keep their freshness and shelf appeal and maintain organoleptic properties.
The benefits to the customer when using PropaFresh P2G and P2GAF are heat sealability on both sides, printability, excellent seal integrity, food contact approved and peelable seals to make the pack easy to open.
“Being able to extend the shelf-life of fresh produce, even for just two or three days, is extremely valuable not only for producers, retailers and consumers, but also for the environment. The advances we have achieved in polymer technology by developing PropaFresh P2G and P2GAF mean we are able to work with the majority of players in the fruit and vegetable arena to ensure the absolute optimum in-pack conditions for their products,” says Clare McKeown, Innovia Films’ market manager of fresh and chilled foods, Europe.
McKeown adds: “Delivering improved shelf-life is also key to reducing food waste and fits in with the waste and resources action programme (WRAP)’s ‘love food, hate waste’ campaign, which recommends that consumers keep prepared fresh produce in the original packaging and refrigerate.”
