For as long as there have been transformers, mineral oils
have been the go-to dielectric fluid, serving to provide electrical insulation and cooling.
are used in packaging adhesives and printing inks, as well as in the manufacturing process.
"There is concern over migration of mineral oil
on recycled paper getting into the food chain," Schuite said.
Andy Sweetman, Marketing Manager Packaging and Sustainability for Innovia Films explained that mineral oil
migration is obviously an area of concern for many dried food manufacturers.
It is envisaged in the future to add certain percentage of rapeseed oil in mineral oil
for use as biofuel .
* At high temperature (225[degrees]C/437[degrees]F), naphthenic mineral oil
showed higher TAN than paraffinic mineral oil
A Smurfit Kappa spokesperson said: "In addition to blocking mineral oil
migration across the whole surface area of the packaging, this new product looks, feels and reacts just like normal board during the manufacturing process.
A low Ibt indicated high mineral oil
repellency against ACP adult settling.
It also offers advantages for packing and converting such as inherent dead fold and anti-static properties, high gloss and transparency, resistance to grease and oil, good barrier to gases, aromas and mineral oils
and a wide heat-seal range.
Many companies have realised the problem and recently some have changed their packaging materials to fresh fibre paperboard printed with inks free of mineral oil
In 2010, a study by Zurich Food Safety Authority scientists using a dedicated measuring method had detected alarming levels of mineral oil
residues from cardboard packaging in food.
"We are obviously accumulating mineral oil
over a lifetime.
