Abstract: Composition of a composite material for containers, method of the preparation thereof and its use. The composition comprises a continuous matrix of a thermoplastic polymer having a melting point higher than 110° C. and, distributed within the matrix, non-fibrillated wood particles having a sieved size greater than 1.0 mm. The weight ratio of thermoplastic polymer to wood particles being 45:55 to 80:20. Material further contains 0.1 to 10% by weight, calculated from the total weight of the thermoplastic polymer and the wood particles, of a slate-like mineral pigment. The material is particularly suitable for containers of cosmetic products, for foodstuff and for beverages.

Abstract: A composition comprising a continuous thermoplastic polymer matrix having a melting point greater than 110° C. and, distributed within the matrix, particles of hydrophilic natural fiber material having a sieved size of less than 1.0 mm, the weight ratio of the thermoplastic polymer to the wood particles being from 99:1 to 35:65. An improvement in biodegradability of biopolymers, such as PLA, can be achieved. On the other hand, the addition of wood fibers enhances the material's ability to resist thermal deformation. The present compositions can be used for manufacturing hollow structures, by injection blow molding, of bottles with a wall thickness between 0.1 mm and 5 mm, in particular from 0.3 to 1 mm or continuous extruded products with a wall thickness from 0.3 mm to 1.5 mm.

Abstract: 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.

Abstract: A composite material, methods of producing it and articles manufactured therefrom. The composite material comprises a first component formed by a renewable polymer and a second component formed by a reinforcing material. The first component comprises a thermoplastic polymer selected from the group of biodegradable polyesters and mixtures thereof, and the second component comprises particles of a hydrophilic material, having a sieved size of less than 0.5 mm. The composite material further comprising regions of elasticity to provide for compostable objects and articles having properties of flexibility or semi-rigidity in at least one dimension. The flexible composite material can be used in thin-walled extruded articles, exhibiting increased flexibility or softness in transversal direction.
