Bilcare Solutions is an international manufacturer of calendered and extruded hard films. Its production and marketing activities are focused on manufacturing hard PVC and PVC-PE films as well as upgrading these films through coating, stretching, laminating and metallizing. Its range also includes extruded PET films. Depending on the required barrier properties, a layer of between 40 and 200 g PVDC needed to be applied to films used in pharmaceutical packaging. To date, continuous measurements were carried out during production on the coating plant using radiometric systems.
