Barrier paper to prevent mineral oil migration
Paper products manufacturer Munksjö has launched Gerstar Mo, a paper developed for packaging applications to protect food from potential contamination by mineral oils.
The a one-side coated barrier paper, Munksjö says, will enable converters and brand owners to develop sustainable packaging made of renewable materials offering maximum consumer food safety.
Made from virgin fibres and suitable for direct food contact, Gerstar Mo is said to provide primary packaging with a mineral oil (MOSH-MOAH) barrier. According to the company, it also prevents cross contamination coming from secondary packaging.
Printable in helio and flexo, Gerstar Mo is suitable for lamination, extrusion or coating, varnishing and hot and cold seal, and is recommended for bags, sachets, pouches and wrappers. Its primary use is for dry food flexible packaging such as biscuits, crisp bread or dehydrated foods. It is available in 50 g/mÇ and over.
“The food packaging industry is particularly attentive to consumer safety and direct food contact,” says Alexandra Venot, vice president of Munksjö’s flexible packaging business unit.
“The market has to meet the increasing health and safety expectations while maintaining high standards of performance. Advances in paper innovation, such as this new mineral oil barrier paper, will help the market move forward sustainably.”
