Aluminium foil for coffee capsules. The coffee capsule foil is a 30 micron thick aluminium foil with a sealing lacquer (thermal lacquer) on the matt inside. The outside is shiny silver but can also be printed. The closure of the coffee capsules is done by heat, which seals the foil to the PP/PVC/PS capsule body.
This foil can also be used to seal food trays.
