Envases Termosur

Located in the city of Puerto Montt, Envases Termosur specializes in manufacturing expanded polystyrene (EPS) boxes, designed for exporting fresh fish.

Also known as plumavit in Chile, EPS is a great thermal insulator, and is also lightweight, waterproof and inert. This makes it a perfect material to keep fish fresh and in optimal conditions until arrival at its final destination.

Termosur manufactures EPS boxes in a variety of different sizes. Its modern plant in Puerto Montt is certified by BRCGS Packaging, a worldwide standard for the safety of food packaging materials.
