The present invention relates to a method for producing a moulded pulp material that is suitable for manufacturing of a packaging unit and such packaging unit. The method of the invention comprises the steps of: - preparing a raw moulded pulp material; - providing the raw moulded pulp material to an extruder; - extruding the raw moulded pulp material; - adding one or more additives; and - providing the moulded pulp material at the outlet of the extruder.

The invention relates to a capsule (100) for preparing a beverage in a beverage production machine. The capsule (100) comprises a capsule body (200) with a sidewall (210) delimiting a chamber (250) for containing a substance (500) for the preparation of the beverage and an injection wall (220) for injecting a fluid in the chamber (250) for preparing the beverage upon interaction of the fluid with the substance (500). The capsule (100) further comprises a delivery wall (300) that is connected to the capsule body (200) to close the chamber (250). The delivery wall (300) comprises, in a layered manner, a retention layer (320) for being opened upon interaction with opening elements under the effect of rising pressure of fluid being injected into the capsule (100) and a filter layer (310) for filtering out particles from the prepared beverage. Each of the filter layer (310) and the retention layer (320) is made of biodegradable material. The filter layer (310) is provided opposite to the chamber (250) with respect to the retention layer (320). The invention also relates to a method for manufacturing the capsule (100) and use of the capsule (100) for preparing a beverage.

An object is to provide a food container and a paper product which are water resistant, oil resistant, and recyclable. Provided is a food container obtained by mixing and stirring water, konjac mannan, and an alkali to liberate an acetyl group to obtain modified mannan whose swelling is suppressed, releasing suppression of swelling of the modified mannan by neutralization to obtain neutral or acidic modified mannan, solating or gelating the neutral or acidic modified mannan, applying the solated mannan sol or the gelated mannan gel to a paper food container, and drying the mannan sol or the mannan gel.

A reinforcement ring for capsules for obtaining beverages, for example coffee, comprising a side wall and a flat surface, preferably having a uniform thickness, protruding from the side wall. The reinforcement ring is characterized in that the side wall comprises a groove at the extremity opposite the flat surface, so as to reduce the thickness of the side wall at the extremity and to reduce the total amount of material used to produce the reinforcement ring. The reinforcement ring can be used to reinforce the body of a capsule for obtaining beverages for example made of a filtering material. A machine for welding the reinforcement ring to the capsule body and to a system for producing beverages comprising a container into which the capsule with the reinforcement ring is inserted during the step of supplying pressurized water.

Packaging devices such as bags, pouches, envelops, containers, and the like, can include an integrated heating system. The packaging devices described herein have multiple potential uses such as for the containment and heating of single-serving meals, drinks, massage oils, masks, body wax, anti-wrinkle eye creams, and the like, to be heated on the go. The packaging devices described herein can also be used for instant heating of food and/or beverages for backcountry use. In some embodiments, the packaging devices use fibrous natural materials (e.g., leaf skeletons and soft biomaterials like chitosan) along with silver nanowires to create completely biodegradable, and reusable self-heating packaging.

The invention relates to a capsule for containing a substance for preparing a beverage by placing the capsule in the cavity of a piston. The capsule has a body with a rim and a sealing ring which is attached to the lower wall of the rim. The sealing ring has an upper face bearing on the lower wall of the ring and a free lower face. The capsule has an inner bearing surface and an outer bearing surface each projecting from the rim forming a groove that is arranged to sealingly receive the peripheral edge of the piston during the preparation of the beverage. At least the outer bearing surface is formed on an inner wall of a ring and formed in one part on the free lower face of the sealing ring.

The disclosed articles, apparatus, methods, and compositions provide for the integration of different and environmentally-friendly processes for extraction, stabilization, and formulation of active compounds with health and/or other benefits from lignocellulosic by-products of food processes. The active compounds can include one or more of polyphenols, flavonoids, o-diphenols, anthocyanins, and phenolic acids. A high-pressure, high-temperature extraction process provides a means to recover a substantial portion of the active compounds from a biomass feedstock. The corresponding extract can be encapsulated, which provides a convenient form for stabilization and delivery of the active compounds into a final product, for example an active packaging material or corresponding actively packaged food item.

A method for discriminating a polyvinyl alcohol resin film containing a polyvinyl alcohol resin in which all or a part of carbon is derived from bio-derived ethylene from a polyvinyl alcohol resin film containing only a polyvinyl alcohol resin derived only from fossil fuel-derived ethylene by measuring an abundance ratio .sup.14C/C of carbon 14 (.sup.14C) in total carbon.

The present invention is directed to a film or coating comprising a fiber material, wherein at least 60% by weight of said fiber material is microfibrillated cellulose, said film or coating also comprising at least 1% by weight of extractives from wood bark or cork wood. The invention is also directed to products, such as packaging materials, using or incorporating said film or coating. Such packaging materials are for example laminates or multi-layer structures. The films or coatings according to the present invention having advantageous barrier properties and are therefore particularly suitable for sensitive objects that need to be packaged in a controlled or modified atmosphere. The present invention is also directed to a composition comprising a fiber material, wherein at least 60% by weight of said fiber material is microfibrillated cellulose, said composition also comprising at least 1% by weight of extractives from wood bark or cork wood. The composition is useful for example in the preparation of the film or coating.
