Semi-rigid containers are among the most versatile of all types of packaging and are widely used for pre-packaged foods, easily withstanding great differences in temperature from freezing to heating. Gränges is a major supplier in this market with a leading position within the semi-rigid container category in North America. As consumers are becoming increasingly dependent on ready-to-eat foods and beverages, the demand for aluminium foils for consumer packaging purposes will rise.
Another end-market in North America is materials for transformers. A transformer is an electrical device used to increase or decrease the alternating voltages in electric power applications. It consists of two or more coils called windings, which are wrapped around a core. In North America, aluminium is becoming more common as winding material in distribution transformers, while copper is more common for large power transformers. Aluminium has significant cost and weight advantages over copper. Gränges is the leading producer of high conductivity aluminium strips for electrical transformers used by utility providers and industrial companies in North America.
