A method for manufacture of a foil for enclosing or wrapping a product to be heated in an oven, comprising the steps of: providing an aluminium layer comprising aluminium, applying a first ink material at a surface of the aluminium layer to form a first ink layer, and applying a second ink material at a surface of the first ink layer to form a second ink layer, the first ink layer thereby being positioned between the aluminium layer and the second ink layer, the first ink layer being adapted for absorbing radiant energy, the second ink layer being adapted for allowing radiant energy to pass through it so as to reach the first ink layer, wherein a binder system of the first and/or second ink material is based on PVB (polyvinyl butyral). |
