ABSTRACT
With pharmaceuticals, metal, particularly tinplate, was at one time widely used for pastille tins, ointment tins and various built-up containers for powders, tablets, capsules, etc. As the early use of tinplate declined, aluminium containers had a period of success, but other than aerosols, are now reducing in usage mainly because of their high cost compared with plastics and glass. However as raw materials vary significantly across the world and processing equipment, once installed, has to justify its initial expenditure, metal usage can vary from country to country.
