Constantia flexibles has developed a 5µm aluminium converter foil, specifically designed for pouch and confectionery laminates. Improved process parameters allow the thinner foil to be processed on a high performance laminator without loss of performance.
The new thickness has been achieved thanks to advances in rolling mill technologies which have enabled enhanced parameters in each of the steps rolling, doubling, separating and annealing, to obtain the thinning to below 5µm, compared with the current standard of 6 7µm.
Envisaged applications include the wrapping of chocolate, confectionery bars and the inner wrappers for gum where a typical lamination would be aluwax or adhesivepaper. It is sustainable cost saving and according to lca carbon footprint reduction by 13 .
