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.

A recyclable paper laminate comprising a water-dispersible barrier against any permeation.

A biodegradable paper laminate comprising a water-dispersible barrier against permeation.

When water pressure transfer of decorative layer or layers is carried out on an article using a water pressure transfer sheet 202 having a non-extensible decorative layer 22 providing hologram function and an extensible decorative layer 24 of print pattern sequentially from a top of said water pressure transfer sheet, a plurality of preformed cracks 26 are formed in said non-extensible decorative layer 22 of said water pressure transfer sheet 201 before said water pressure transfer sheet 202 lands on water, then an activating agent for wetting and activating said extensible decorative layer 24 is applied, and thereafter said water pressure transfer sheet lands on the water whereby water pressure transfer is carried out having high profile followability.

A peel-openable package includes a lid. The led includes a sheet member located at a position corresponding to a container portion of a package main body, and a film member bonded to a surface of the sheet member. Cutouts running in a thickness direction of the members and are formed in a peel region defined in a foldable portion of the members. The cutouts and cross a longitudinal direction L and are away from each other by a predetermined interval extending in the longitudinal direction. Facing surfaces of the sheet member and the film member, which are in the peel region corresponding to an area between the cutouts, are bonded together so as to be peelable from each other by an adhesive layer.

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.

A film for packaging useable with foodstuffs comprising a paperboard or biopolymer base material, a base coat structure, a metallized layer, and a top coat structure. The base coat structure has one or more layers, each having a weight less than or equal to 1% of the base material and of differing chemical composition and the sum is less than or equal to 5% of the structure weight. The metallized layer is on the base coat structure to an optical density of between 2.0 and 4.5. The top coat structure has an outer and an inner layer, with each layer less than or equal to 1% of the weight of the base material and of differing chemical composition. A bag made from such a film is likewise disclosed, as is a film without a metallized layer.

The invention relates to the field of cups, bowls and containers, particularly beverage cups, and to the production of cups, bowls and containers. According to the invention, the cups, bowls and containers comprise, in a first variant, a first layer (5) made of cellulose hydrate, also known as cellophane, or cellulose hydrate which is coated with a primer material (4). In addition, the cups, bowls and containers can comprise a second layer (3), made of paperboard or fibre/cellulose-starch mix, for example. In a second variant, the cups, bowls and containers according to the invention comprise a first layer made of natural rubber or plant-based wax and a second layer made of cellulose hydrate, paperboard or fibre/cellulose-starch mix. By using exclusively biodegradable materials, the present invention can provide completely biodegradable/compostable cups, bowls and containers. The invention also relates to a method for producing such cups, bowls and containers. In addition, the present invention also comprises the production of lids made of the aforementioned materials and the provision of cups, bowls and containers having such lids.
