Do I understand this correctly: I laminate my printout with this film and the result is then self-adhesive? I.e. the glue in the foil pocket inside sticks together when heated, the glue on the one outside still works after the laminating process? Obviously you are making quite a mess of this feature. If I change the format of this product to A5 or the film thickness to 125 µm, the 'Self-adhesive' feature is missing from the specs...
