A container made of a sheet material including a plurality of layered film layers including a first film layer and a second film layer. The sheet material is formed into a bag by attaching at least a part of a periphery of the sheet material to form a containing region for accommodating a content inside the second film layer. The container includes, between the first film layer and the second film layer, a film attached portion where the first film layer and the second film layer are attached to each other, and a filler enclosed portion bulged out to a thickness direction of the sheet material than the film attached portion because the filler is present therein. A printed layer including an ink layer is formed on at least one surface selected from outside and inside surfaces of the first film layer, and outside and inside surfaces of the second film layer, and the printed layer is removable from the surface of the film layer by washing with an aqueous solvent.

The present invention is directed to a curable polymer comprising: a base acrylic monomer (monomer A); a monomer with bioactive functionality (monomer B); a monomer containing a cross-linker (monomer C). The present invention also relates to a method of making a polymer coating on a solid support. The present invention also relates to a method of preserving a product.

A blow molded multilayer article with a hollow body defined by a wall with an inner surface and an outer surface. The outer surface has an axial color gradient and/or a gloss gradient. The wall has multiple layers and at least one layer contains an effect pigment and/or an opacifying pigment.

A method of producing a directly blow-formed container. The method includes subjecting a multilayered parison having an inner surface formed of an olefin resin to direct blow forming, the olefin resin containing (i) an organic bleeding lubricant having a melting point of not higher than 50° C. in an amount of 5 to 10% by mass, and (ii) a high silica zeolite having a silica/alumina mole ratio of not less than 80 in an amount of 0.2 to 3.0% by mass.

A composition of matter having oxygen scavenging properties comprises a blend of a base polymer, a butadiene polymer, and titanium dioxide in an amount sufficient to catalyze reaction of oxygen with the butadiene polymer. In further aspects, methods for making the compositions herein and packaging film structures comprising the compositions herein, and packaging articles formed of the same, are also provided.

A biodegradable packaging material, a method of manufacturing the same, as well as products made of the material wherein the manufacture comprises extrusion onto a fibrous substrate one or more polymer coating layers including at least one layer of a polymer blend consisting of (i) 20-95 wt-% of polylactide having a high melt index of more than 35 g/10 min (210° C.; 2.16 kg), (ii) 5-80 wt-% of polybutylene succinate (PBS) or a biodegradable derivate thereof, and (iii) 0-5 wt-% of one or more polymeric additives. The components of the blend are melted and blended in connection with the extrusion step. The goal is to improve extrudability, increase machine speed in extrusion and maintaining good adhesiveness to the substrate and good heat-sealability of the coating. The products include disposable drinking cups and board trays, as well as sealed carton packages for solids and liquids.
