The objective of the present invention is to provide a composite separation membrane which is excellent in not only a liquid permeable performance and a separation performance relatively but also a durability and which is particularly useful as a membrane for liquid treatment, and a method for treating a liquid by using the composite separation membrane. The composite separation membrane according to the present invention is characterized in comprising a supporting base material and a complex layer, wherein the complex layer is placed on the supporting base material, the complex layer comprises oxidized metal nanosheets, graphene oxide and an alkanolamine, and at least one of the alkanolamine is present between the oxidized metal nanosheets.

The disclosure is directed to methods of manufacturing protective packaging materials, as well as the protective packaging materials produced using the disclosed methods. These packaging materials can be biodegradable, compostable, and/or recyclable.

The present invention relates to a method for manufacturing of a laminated cellulose-based liquid or semi-liquid food packaging material, wherein the laminated packaging material has a bulk material layer of paper, paperboard or other cellulose-based material, an innermost, heat sealable and liquid-tight layer of a thermoplastic polymer, the innermost polymer layer intended to be in direct contact with the packaged food product, a barrier layer laminated between the bulk layer and the innermost layer. The invention further relates the laminated packaging materials obtained by the method and to a packaging container for liquid food packaging, comprising the laminated packaging material or being made from the laminated packaging material obtained by the method.

A display apparatus includes a display panel including a central area and an outer area outside the central area and which is bent. A cover panel includes a cover central area overlapping the central area, a cover outer area overlapping the outer area, a light-blocking layer on the display panel and a groove layer disposed on a first surface of the light-blocking layer opposite to a second surface of the light-blocking layer facing the display panel. A plurality of grooves is defined in the groove layer in the cover central area.

A packaging material including a film that is biodegradable and compostable, wherein at least one aperture is formed in the film. The at least one aperture is structured and distributed such that the film controls oxygen permeability and water vapor permeability to such an extent that when the film encompasses a food product that is initially fresh the food product will remain fresh for at least one additional day when compared with the case that the film is replaced by a plastic that is not biodegradable and compostable.
