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.
