Semi-rigid packaging includes trays and containers made from thin aluminum strips. MC Aluminum is simply produced by deep drawing using a standard deep drawing press. Container foil is heat-resistant, retort-resistant, safe and hygienic, and available in a variety of colors. It is mainly used for portion packaging of frozen food and ready-to-eat food in catering companies and aircraft catering, as well as jam, honey, milk and sausage products.
