Cellulose-based renewable and compostable packaging films from Innovia Films are designed to offer the necessary oxygen and moisture barrier properties required for dried foods.
NatureFlex compostable packaging films have now been scientifically tested and also proven to provide an effective barrier against mineral oil residues.
A recent scientific study at the Zurich Food Safety Authority in Switzerland, using the same series of tests to prove the efficacy of compostable NatureFlex films established the presence of alarming levels of mineral oil residues transferring from recycled cardboard packaging into food.
According to Dr Koni Grob, who led the Swiss research team, toxicologists have linked mineral oils to inflammation of internal organs and even cancer.
Mineral oil residues in food have been tracked to the printing inks present on the packaging surface as well as in recycled newspapers used in the production of cardboard packaging. These residues can migrate even at room temperature and be deposited on dried foods packaged in the box such as pasta, rice and breakfast cereals.
NatureFlex compostable packaging films from Innovia Films can be used in several ways as a barrier solution for dried foods including as pouches, bag in box and board lamination.
Product manager at NatureFlex Films, Paul Barker confirms that the tests conducted on the compostable films showed that they provided a very good barrier against mineral oil residues when used as the inner bag or pouch.
The compostable film additionally protects packaged dried foods against oxygen and moisture to ensure optimum product quality and maximise shelf-life.
Innovia Films supplies renewable and compostable films to converters, brand owners and end-users across the globe for most types of food packaging. NatureFlex films comply with European standard EN 13432 for compostable packaging, offering an alternative disposal route and diverting waste away from landfill sites.
