摘要:
A method for manufacturing biodegradable products with a blown foamy structure, wherein a mass comprising at least natural polymers such as starch is passed under pressure into or through a mould (23, 63) and the mass (M, S) is heated in the mould (23, 63) in a manner such as to give rise to at least cross-linking of natural polymers, while the mass prior to the introduction into the mould has a temperature which is below the gelatinization temperature and in the mould is brought at least to the baking temperature.
