The present invention relates to a vegan and reusable leather type material of vegetable origin, at least 50% and preferably at least 80% biobased. This material is based on a composition which comprises persimmon (Diospyros kaki) mass and a polymer derived from a polyol of vegetable origin. The invention also discloses the process for obtaining the material. The leather-type material may be used in a variety of goods products in the textile such as clothes, footwear products or accessories. The material has proven to keep the same mechanical properties as the animal origin or synthetic leather, being a sustainable alternative which, in addition, contributes to circular economy. The sustainable material, leather-type of vegetable origin, provides an alternative to known leathers, with less environmental impact.

The presently disclosed subject matter is directed to a polymeric, multilayer film suitable for use in a variety of applications, including (but not limited to) the manufacture of bioprocessing containers. The disclosed film comprises a sealant layer comprising: (i) one or more ethylene/alpha olefin copolymers with an average density lower than 0.922 g/cc; (ii) one or more polymers with an average density higher than or equal to 0.950 g/cc and selected among ethylene/alpha olefin copolymers and/or ethylene homopolymers; (iii) high molecular weight siloxane polymers; optionally, at least one gas barrier layer and an outer skin layer. The sealant layer of the disclosed films provides for a low blocking effect and for high seal strength. In addition, the surface of the sealant layer is inert and substantially free from migratory surface additives and from metal containing particulate additives, such that, when the film is used for manufacturing bioprocessing containers, cell growth and products harvesting are not affected. A method for manufacturing the film, a bioprocessing container comprising the film and a method for culturing cells in such container are also herein disclosed.
