Clondalkin Flexible Packaging Wentus has developed a new WENTOPRO barrier film for dry food products.
The new multi-layer film claims to prevent the migration of potentially harmful mineral oils from the outer packaging into the food itself.
When used as a bag in box liner for dry foods, including rice, dry pasta, dry noodles, baby food and cereal products, the film provides a barrier against mineral oil saturated hydrocarbons (MOSH) and mineral oil aromatic hydrocarbons (MOAH).
Said to cause inflammation of internal organs, the mineral oil hydrocarbons are derived from printing ink used in newsprint, which is commonly used to make recycled cardboard for food packaging.
To overcome such health hazards, WENTOPRO is available in two variants, including WSL 143031 and WSL 143040.
WSL 143040 claims to offer a barrier against MOSH and MOAH, while WSL 143031 offers additional protection, not just against mineral oils, but also against UV photoinitiator exposure, used in curing inks on cardboard and food labels.
As recommended by the German Federal Ministry of Food, Agriculture and Consumer Protection (Bundesministerium für Ernährung, Landwirtschaft und Verbraucherschutz – BMELV), migration of MOSH should not exceed 2mg/kg and MOAH levels should be no higher than 0.5mg/kg. The company says the new film has typical values less than 0.2mg/kg for both.
These products also offer a high barrier against water vapour, have excellent strength and sealing properties and are compatible with different types of sealing machines, claims Clondalkin.
Clondalkin Flexible Packaging Wentus business development director Christian Claes said: "The development of the WENTOPRO barrier film is an important advance for the food packaging industry.
"The subject of mineral hydrocarbon exposure through food and the potential consumer health risks of this is a hot topic at the moment. Our protective film offers food manufacturers protection and reassurance that their products carry very limited risk of any such contamination."
