摘要：
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.
