Laminated and/or coated Aluminum Foil in our internal processes:
Laminated Foil: the aluminum is brought together, by means of adhesion, pressure and temperature to another substrate. These can be bi-laminated (aluminum + plastic or paper) and tri-laminated (aluminum + plastic + paper)
Coated foil: a coating is applied to the aluminum, which can be a first dye or thermo-sealable spray; such as: blister foil.
