A biopolymer film is provided that comprises a combination of crystalline nano cellulose (CNC)/esterified crystalline nano cellulose (ECNC) reinforced with chitosan. The two polymer components can be present in any ratio, but an approximate CNC to ECNC 70:30 ratio is preferred. The chitosan component is derived from exoskeletons of crustaceans. Also provided are methods of preparing biopolymer film and preparing food packaging components from said biopolymer film. The CNC/ECNC mixture is dissolved in an ethanol solution and the chitin is dissolved in acetic acid and mixed together to form a polymer blend.

Disclosed herein is a degradable cellulose ester. The cellulose ester may be formed into tow for use in cigarette filters or into articles, such as molded articles. A basic material, an enzymatic material, or combinations thereof is included in the cellulose ester in order to degrade the cellulose ester.

Formulations for producing modified bio-based polymers, especially bio-based polyesters like PLA and/or biodegradable polymers like PBAT, include at least one organic peroxide and at least one bio-based reactive additive. The at least one organic peroxide and/or the at least one bio-based reacted additive are capable of reacting with a bio-based polymer and/or biodegradable polymer to produce the modified bio-based and/or modified biodegradable polymer. The modified bio-based and/or modified biodegradable polymers have improved properties compared to non-modified bio-based and/or biodegradable polymers. The improved properties may related to processability, especially improved melt strength which results in easier processing while producing foamed polymers, thin films, such as blown film, cast film, tentered film and the like. The improved properties may be related to physical properties such as improved stiffness, toughness or tensile strength.

A medical material comprising film obtained from a polyester wherein the polyester has a weight average molecular weight of 1,250,000 or greater determined by gel permeation chromatography calibrated with polystyrene standards. The polyester comprises a 3-hydroxybutyrate unit and a 4-hydroxybutyrate unit as polymerization units, and proportion of the 4-hydroxybutyrate unit relative to all monomer units is from 14 mol % to 40 mol %. The polyester film is useful for medical apparatus, packaging material for food, plastic sheet for agriculture, flowerpots for seedings, and sheets for construction and engineering.

The invention relates to a food packaging unit (20) comprising a food container (1) for receiving a liquid, pasty or free-flowing food. The injection-moulded, single-component, cup-shaped base body (2) of the food container surrounds, with a wall (5), a bottom (6) and an outwardly projecting collar (7), an opening (4) which is closed by a food-container-covering film (10) applied to the collar (7). The food container (1) is injection-moulded in a single layer from a polymer blend comprising two components, a first component of which being PVOH or a PVOH copolymer. The food-container-covering film (10), which can be applied to the plastic food container (1) in order to close the opening (4) by sealing, welding or adhesion, comprises a cellulose-containing layer which is coated with PVOH, or a PVOH polymer blend layer.
