Zanbarrier NGR is a new fluorocarbon-free natural barrier paper. Due to a special manufacturing process, the use of fluorocarbon or other chemicals is completely unnecessary to ensure its function as a barrier.
It will be presented at FachPack in Nuremberg during September, alongside the company’s versatile range of label paper and cartonboard, including the high gloss qualities of the Chromolux premium brand, which is celebrating its 60th anniversary this year.
The abbreviation NGR in Zanbarrier NGR stands for ‘natural grease resistant’. In the unique production process of Zanbarrier NGR, the cellulose fibres are subjected to an incredibly intense grinding process over several refining stages. The surface area of the fibre is greatly enlarged, so that the absorption of water into the fibres is greatly increased, creating a gel-like fibre mass, in technical jargon ‘slow draining’ because the fibres actually feel greasy after refining.
The cellulose fibres treated in this way form a tight, strong cross-linked sheet structure on the paper machine, creating a finished paper which has a 100% natural barrier to oil and grease without the use of fluorocarbon or other chemicals.
The applications for the new Zanbarrier NGR are identical to those of conventional barrier papers. In this way, all flexible food packaging requiring oil and grease-resistance as well as wet-strength papers is fully catered for.
