Other end-customer markets

In North America, Gränges is one of the major suppliers of aluminium foil for food containers and winding material for transformers.

Aluminium foil provides a complete barrier to light, oxygen, moisture, and bacteria. These properties make it ideal for food cartons and pouches. Container foil is divided into three major categories: household/institutional foil, semi-rigid containers and flexible packaging. For decades, the use of foil has grown steadily in each of these categories. 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.

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 plays an important role in the design of electrical distribution and large power transformers thanks to its significant cost and weight advantages versus copper.

The markets for semi-rigid containers and transformer windings made in ­aluminium are expected to show stable annual growth.
