Abstract: The invention relates to a metallized multilayer sheet material for packaging having a water vapour transmission rate of below 5 g/m2/day at 38° C. RH:90% comprising: a water vapour permeable sheet substrate, and at least two metallized layers, each covered directly by a solvent based polymeric coating layer, wherein the cumulated metallized layers have an optical density of at least 2.5 and/or a thickness of at least 15 nm.

Abstract: 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.

Abstract: The present invention relates to woven or nonwoven fabric material having antimicrobial activity, and to its uses ranging from wound dressing, facial masks, surgical drapes and surgical clothing, to filter materials and similar applications where the antimicrobial effects are employed, as well as to a process for the preparation of the woven or nonwoven fabric material.

Abstract: A metallized barrier material comprising a base material, a metallized layer and a protective coating. The base material has a first surface and a second surface. The metallized layer is vapor deposited on the first surface of the base material to a desired optical density. The protective coating is applied to the metallized layer, wherein the protective coating comprises a butyl methacrylate or a combination of an epoxy component and an acrylic component wherein the epoxy component has an EEW of less than 800.

Abstract: A film for use in association with packaging useable with foodstuffs having product contact comprising a base material, a base coat structure, a metallized layer, and a top coat structure. The base material comprising a paperboard material or a biopolymer. The base coat structure has an optional plurality of layers, with each layer having a weight that is less than or equal to 1% of the weight of the base material and of differing chemical composition and the sum of all non-biodegradable coated layers is less than or equal to 5% of the base material weight per unit area. The metallized layer is applied directly onto the base coat structure to an optical density of between 2.0 and 4.5 optical density. The top coat structure has an outer and an inner layer, with each layer having a weight that is less than or equal to 1% of the weight of the base material and of differing chemical composition from each other and the base coats.
