Sappi has optimized its Guard M and Guard MS papers with an integrated mineral oil barrier.
Thanks to its mineral oil barrier (MOB) and grease barrier, the four sustainable papers from the Sappi Guard family offer product safety and can be entirely recycled.
René Köhler, head of business development packaging and speciality papers at Sappi, said: ‘The integrated mineral oil barrier prevents MOSH and MOAH compounds from penetrating into the packaged goods. On the one hand, this makes additional special coatings or laminations superfluous. On the other, brand owners can use recycled paper or cardboard for the outer packaging and dispense with fossil-based materials.’
Sappi Guard M has a mineral oil barrier and with Kit 11, a very high grease barrier. Sappi Guard MS also impresses with its heat sealability, eliminating the need for additional production steps and materials as sealing media. The grease barrier is Kit 7.
Sappi offers both papers in two variants: ‘Nature’ is uncoated and has a natural, more tactile feel, whilst ‘Silk’ stands out with enhanced printing results and a silky matte appearance.
The Guard portfolio is marketed for primary or secondary packaging for dry and slightly oily foods such as pasta, rice, cereals and various powders. Guard M barrier papers are also suitable as liners for transport packaging, as they prevent mineral oil from recycled cardboard and paper from migrating into the food. Sappi supplies all Guard papers on request with FSC or PEFC certification, which underscores the brand owners’ commitment to sustainability
