Features

Protecting the product remains the number one priority of our customers. Maintaining the product’s quality throughout its shelf life is important and in some instances, shelf life expansion is desirable.

For many foods and particularly dried foods, moisture ingress may be detrimental and the packaging needs to present a barrier to water vapour. Equally, many food ingredients are susceptible to oxygen deterioration and therefore demand protection from oxygen.

Our range of Propafilm™ film presents a wide range of barrier films that demonstrate excellent moisture and gas barrier. Discover the options with our BOPP films.

  •  Excellent moisture barrier makes our BOPP films ideally suited to dry products wrapping.
  • Films with excellent gas barrier available, for gas flushing applications or for products which suffer from oxygen deterioration.
  • Films with aroma barrier properties to protect delicate flavors.
  • UV barrier possible through a choice of white films.
  • Mineral oil barrier solutions, validated by an external independent laboratory.
  • Hermetic sealing films enable further protection in the seal area.

Mineral Oil Barrier

Innovia Films has dedicated extensive scientific research into the subject of mineral oil migration through BOPP films. Quantitative analyses were completed in our in-house laboratories and published in the Packaging and Technology and Science journal. The effectiveness of our solutions has also confirmed in tests performed by the laboratories of Kantonales Labor Zürich. 

  • Our Propafilm™ RCU solution has been designed to meet the finding of our study from 20141.
  • Propafilm™ RCU  has been shown to significantly reduce the migration of mineral oil residues from recycled cardboard packaging into foodstuffs when compared to conventional plastic substrates e.g. PE, coextruded OPP1
  • Propafilm™ RCU has been confirmed to provide an equivalent mineral oil barrier to 3 years at room temperature, as tested by Kantonales Labor Zürich.2

2  The test method used for these tests is based on the publication ‘Barriers against the migration from recycled paperboard into food : Measuring efficiency by surrogate components’, S. Biedermann-Brem, K. Grob, Packaging Technology and Science 27 (2014) 713-726’.
Certain parts of the test procedure were modified as followed :
  • The 3 surrogates were applied to the recycled cardboard (donor) and the concentrations were of 30-40 mg/kg for each component.
  • Triethyl citrate (TEC) is no longer used as surrogate.
  • Surrogate components : n-heptadecane (C17), 4-methyl benzophenone (MBP) and dipropyl phthalate (DPP).
  • The barrier is considered sufficient if <1% of the surrogates migrate in the shelf life of the product.
