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.
Its development has been the result of proactive investigation into the mineral oil hydrocarbon (MOH) and mineral oil aromatic hydrocarbon (MOAH) barrier protection of their films. It included the evaluation of films with multiple laydowns, increased coat weights and one side/two side variations. This work commenced after studies identified foods were being contaminated by migration of mineral oil from paper-board packaging.
Further studies by the UK Food Standards Agency highlighted safe levels were often exceeded in food packaging samples that were tested. .
Innovia findings proved their 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. The film, besides offering excellent barrier, has 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).
