Innovia Films has launched its first BOPP film that has been officially proven to provide up to 1.5 years' protection from mineral oil migration.
Propafilm RCU is the result of "proactive investigation" into the mineral oil hydrocarbon (MOH) and mineral oil aromatic hydrocarbon (MOAH) barrier protection of the company's films. It included the evaluation of films with multiple laydowns, increased coat weights and one side/two side variations.
This work commenced after earlier studies by Dr Koni Grob from the official Food Control Authority of the Canton of Zurich, Switzerland, identified that foods were being contaminated by migration of mineral oil from paperboard packaging. Further studies by the UK Food Standards Agency highlighted that safe levels were frequently exceeded in food packaging samples that were tested.
Innovia says its research findings proved that its proprietary acrylic coated film provides an effective barrier to mineral oil migration. Further analysis identified the optimum coat weight of acrylic required to maximise the barrier protection. This has meant that the development of Propafilm RCU has been fairly rapid.
In addition to offering excellent barrier, the film is said to have superior optical properties, a low sealing threshold and a broader sealing range which makes it ideal for use in a variety of markets (biscuits, bakery, confectionery, dried foods, tea and cereals). It is "ideal" for pre-made bags and lamination to other films.
