“…Usually water‐insoluble substances like mineral oil are most probably not removed at all. Therefore MOSH and MOAH can be found in (nearly) every cardboard packaging material which has been manufactured by use of a certain amount of recycled fibres . Also compounds from printing inks had been found in cardboard packaging materials, from which they can migrate into food or food simulants .…”

Polymeric barrier membranes are widely used in the food packaging area. So‐called functional barriers prevent the packed food from contamination of permeants from the environment or from other packaging components. Aim of the study was to determine barrier properties of non‐polar n‐alkanes (n‐pentane up to n‐tetradecane) and polar 1‐alcohols (1‐propanol to 1‐octanol) of a 12 µm biaxially oriented PA6 film at temperatures between 70°C and 100°C. From the experimentally determined lag times, the diffusion coefficients DP as well as the partition coefficients K of the investigated permeants were calculated. From the correlation between the molecular volume V and the diffusion coefficients DP, the lag times for lower temperatures can be predicted for temperatures between 20°C and 70°C. In conclusion, the investigated 12 µm PA6 film is a sufficient barrier towards organic compounds. The permeation of substances with molecular volumes above 200 Å3 is negligible for a shelf life of three years and temperatures below of 60°C. These storage conditions are sufficient for nearly all kinds of food packaging applications. Copyright © 2016 John Wiley & Sons, Ltd.

“…For example, polyamide (PA) as well as polyethylene terephthalate (PET) showed very good barrier properties towards mineral oil saturated hydrocarbons (MOSH) and mineral oil aromatic hydrocarbons (MOAH). MOSH and MOAH are contaminants from printing inks found in cardboard packaging materials that have been manufactured by use of a certain amount of recycled fibres . PET and PA are therefore promising barrier materials towards mineral oil hydrocarbons, which might prevent the packed food from contamination.…”

Polymeric materials can be used as functional barriers to prevent contamination of food from the environment or from other packaging components, e.g. mineral oil hydrocarbons from printing inks. Polyethylene terephthalate (PET) is such a promising barrier material. From permeation studies found in the scientific literature lag times, diffusion coefficients or permeation rates towards organic chemicals could not derived because of the slow diffusion process of the permeants in PET. Knowledge about lag times or diffusion coefficients for different permeants, however, is essential for the evaluation of the barrier properties of PET films towards organic contaminants, e.g. mineral oil hydrocarbons.The aim of the study was to develop automated permeation testing method in order to determine the lag times of high-barrier films. From the lag times, the diffusion coefficients as well as the partition coefficients of the alkanes were calculated. In addition, the permeated amounts were simulated by use of diffusion models. Therefore, the lag times can be predicted under different experimental conditions as used in the current study. The results of this study show that the investigated 12 μm PET film is an effective barrier towards mineral oil hydrocarbons. For example, the predicted lag time for n-octane or n-dodecane at 40°C is 8.8 and 210 years respectively.

A method is described for determining the breakthrough periods through various types of potential functional barriers. A donor pack with a sheet of paper containing the test migrant(s) was tightly fixed to one side of the barrier. It included a blank sheet of paper as a spacer to rule out wetting contact between the donor and the barrier. A polyethylene film acted as a receptor on the other side. Periodically, a piece of the receptor film was analysed for the test migrants broken through the barrier. As benchmarks, periods were extrapolated for 1% and 10% breakthrough compared with equilibration. Tests were performed at 60°C, 40°C and ambient temperature. Acceleration by increased temperature gave reasonably adequate results for polyethylene but too short breakthrough periods for polypropylene, owing to structural changes in the polymer. The donor pack also included Sudan red 2, which is of sufficient volatility to migrate through the gas phase. It enabled visual control for gaps and holes in the barrier layers or cracks, e.g. from manipulation (such as bends or scratches), by red spots in the tested material behind the barrier or in the receptor film. Breakthrough data for mineral oil of the type typically used in cold‐set offset printing inks are provided for a selection of materials. Polyethylene terephthalate and polyamide showed no breakthrough for a period corresponding to 6.9 years. Copyright © 2011 John Wiley & Sons, Ltd.
