The present invention is directed to a packaging material free from aluminium in the form of a continuous foil or film, comprising a layer of microfibrillated cellulose (MFC), wherein the layer comprising MFC has been laminated or coated on at least one side with a heat-sealable material. The MFC layer contains at least 60% by weight of microfibrillated cellulose. The present invention is also directed to a method for induction sealing, wherein a packaging material to be heat-sealed by induction is placed against an induction heating surface.

A biodegradable cellulose fiber-based substrate, at least one side of which is coated with a release coating including: a) at least one water-soluble polymer (WSP) containing hydroxyl groups, and b) at least one lactone substituted with at least one linear or branched and/or cyclic C.sub.8-C.sub.30 hydrocarbon chain which may contain heteroatoms. The biodegradable substrate is certified biodegradable in accordance with EN 13432. A method of production thereof is also disclosed.

A formed body includes a base material, an adhesive layer, and a cellulose acylate film. The base material is formed of a thermoplastic resin and is in the form of a transparent sheet. The adhesive layer bonds the base material and the cellulose acylate film. The cellulose acylate film has a thickness in a range of 15 m or more and 100 m or less, and is formed of cellulose acylate including an ester oligomer or a sugar ester derivative.

A cellulose fiber-based substrate, at least one side of which is coated with an aqueous mixture composed of: a) at least one water-soluble polymer (WSP) containing hydroxyl groups, b) at least one lactone substituted with at least one linear or branched and/or cyclic C.sub.8-C.sub.30 hydrocarbon chain which may contain heteroatoms, c) at least one crosslinking agent. A method of production and use thereof.

An object of the present invention is to provide a cellulose-based sheet which has excellent transparency, and exhibits excellent adhesiveness when thermally press-adhered. The sheet includes a laminate including a layer formed of a cellulose-based material and a layer formed of a thermoplastic elastomer. Each of molecules forming the thermoplastic elastomer has both a rubber component having entropy elasticity and a molecule-constraining component for preventing plastic deformation.

An interlayer structure having a cellulose ester layer for use in structural laminates is described herein. The cellulose ester layer provides rigidity and support to multilayer interlayers comprising an array of different layers. Due to the diverse properties of the cellulose ester layers, the present interlayers can be useful in producing structural laminates having high stiffness and which possess good optical clarity for a variety of applications, including outdoor structural applications.

Anti-fog compositions comprising a primary film having opposing major planar surfaces and a central coplanar region, and processes for making such anti-fog compositions. The central coplanar region is disposed between the opposing major planar surfaces. The primary film comprises cellulose acetate, plasticizer, and an anti-blocking agent. The anti-blocking agent has an average particle size ranging from 0.02 microns to 6 microns. The cellulose acetate has a degree of substitution that increases from the opposing major planar surfaces toward the central coplanar region or that is substantially constant throughout the thickness of the composition. The composition is formed by saponifying a precursor film to improve hydrophilicity.
