摘要:
A container for cosmetic products and a method of manufacturing the same. The container, such as a jar, has a wall formed by a first layer of a compostable material which comprises in combination a biodegradable polymer which forms a continuous matrix and, mixed therein, particles of a hydrophilic material capable of swelling inside the matrix upon water absorption. The container further comprises a second layer of a compostable material which comprises a biodegradable polymer which forms a continuous matrix and which is essentially free from particles of a hydrophilic material capable of swelling inside the matrix, or contains essentially less of them than the first layer. The container is degradable in compost, disintegration of the container wall, at 58° C., occurring within 12 weeks.
