A large lightweight 3-D shaped molded pulp material, for example a container, comprising a large pulp molded outer shell lined with a reinforcing core spacer material, conforming to and adhering to said shell, and an inner shell made of molded pulp or a flexible paper based material. A method for manufacturing such a lightweight material involves pressing slurried pulp between a first male mold half [5] covered with elastomeric material [6] and a second female mold half [3], to form the molded pulp outer shell [17], and gluing the reinforcing core spacer material [18] to the interior of said molded pulp shell [17] and gluing the inner shell to said spacer material.
