Biodegradable Fresh Produce Film Extends Shelf Life
Packaging leaders have created a transparent film that is not only biodegradable, but can also extend the shelf life of fresh food produce.
Plastiroll, one of the primary manufacturers of biodegradable film in Europe, has provided a packaging solution to fresh produce, such as fruit and vegetables, by prolonging their short shelf life. The film is crafted from cornstarch-based ingredients that produce a breathable and biodegradable membrane that is also high in strength and gmo-free.
“Our new bio-film is an ecological alternative to conventional plastic films with the same physical properties. There is a demand for packaging materials with good green credentials as long as they perform as well as or better than conventional films,” said Plastiroll’s Product Development Manager, Jani Avellan.
He added that the solution offers less waste and cost savings from preserving food for longer. The biodegradable film can be disposed along with other food waste.

The packaging film can be sealed and used within a carton tray or box, or on its own. It is available in several thicknesses and widths depending on consumers’ requirements. European customers have thoroughly trialled the product and testified significant increases in fresh produce shelf-life. Plastiroll developed the film to an optimum balance between controlling humidity and the permeability of carbon dioxide and oxygen, which allows the product to degrade more slowly.
Bio products produce less waste, and therefore contribute to a sustainable future. In the manufacturing process, it also takes less heat and energy to seal the bio-films, in comparison to their conventional plastic counterparts.
The company notes that the key to the product is down to a “sandwich” of materials with different properties. The correct combination of this multi-layered film provides a better tolerance to gases, water vapour and grease.
The latest packaging invention follows Plastiroll’s 2010 investment to double production capacity for biodegradable films and extend their product range.
The company has manufactured packaging materials since 1983, but began a program of producing biodegradable packaging in 1997. Based in Finland, Plastiroll has around 75 employees, and a 28 million euro turnover.
