Alufel is a thin layer of annealed Aluminum. It has great resistance to high temperatures, up to around 500°C and to weathering. The 30 and 50 micron version is available with an acrylic based sticker with high adherence. While the non-adhesive version is available in 100 and 200 micron thicknesses with surface treatment on both sides.
Alufel supply is usually in rolls that are suitable to be used with standard thermal transfer printers, using for the print-out some ribbons of wax/resin or resin type. For the versions with adhesive, we can supply the tags also in fanfolds.
