A BARRIER SYSTEM
A packaging material is provided including a substrate, and an oxygen transmission inhibiting layer that is carried by the substrate. The oxygen transmission inhibiting layer is formed of a composite material including a linear polysaccharide medium within which one or more additives are dispersed. The composite material is capable of forming a substantially continuous film to provide a barrier to transmission of oxygen gas. The oxygen transmission inhibiting layer is configured within the packaging material at a thickness that is efficacious in inhibiting the transmission of oxygen gas therethrough. A packaging device has two or more component parts, at least one of which is formed of the packaging material. The component parts of the packaging device are shaped and/or configured to be assembled to define an interior region within which goods are to be contained.
COATED SUBSTRATE
A substrate coated with a first coating composition comprising an alcohol-based binder and an inorganic particulate material and a second coating composition comprising a latex binder and a phyllosilicate, and methods for making said coated substrate.

DECORATION SHEET HAVING MICROPATTERN, AND METHOD FOR PRODUCING SAME
Provided are a decoration sheet and a method for producing same, the decoration sheet sequentially comprising a thermosetting resin layer, a deposition layer, and a base layer, wherein the thermosetting resin layer has a micropattern on a surface thereof, and the elongation rate of the sheet is 200% to 300%.
Security document having enhanced foil durability
A security document, along with its methods of formation, is provided. The security document may include a base sheet, a colored coating on the base sheet, a foil laminate on at least a portion of the colored coating, and an outer lacquer coating over the colored coating such that the foil laminate is embedded between the colored coating and the outer lacquer coating. The outer lacquer coating may include a polymeric resin, and may also include a crosslinking agent and a wetting agent.

HEAT SEALABLE BARRIER COATINGS FOR PAPERBOARD
A paperboard blank and cup made therefrom are provided. The blank includes a paperboard substrate having a first side and a second side. A first polymer layer can be disposed on at least a portion of the first side of the paperboard substrate, and a second polymer layer can be disposed on at least a portion of the second side of the paperboard substrate. Both the first and second polymer layers can include at least one polymer component that is thermoplastic. The second polymer layer further comprises at least one polymer component, which is not present in the first polymer layer, and has a glass transition temperature higher than all the polymer components of the first polymer layer.
Method for manufacturing biodegradable packaging material, biodegradable packaging material and packages and containers made thereof
A biodegradable packaging material, a method of manufacturing the same, as well as products made of the material wherein a multilayer coating coextruded onto a fibrous substrate the multilayer coating comprising innermost and outermost layers of a blend comprising 20-95 wt-% of a higher melt index polylactide and 5-80 wt-% of another biodegradable polymer such as polybutylene succinate, and a middle layer containing a lower melt index polylactide alone. The goal is to increase machine speed in coextrusion while 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.

BIOPOLYMER COATING FOR COMPOSTABLE PAPERBOARD PACKAGING
A coating for paperboard includes polylactic acid and an inorganic material. The inorganic material may be talc. The presence of the talc has a beneficial effect on extrusion processing behavior including lower melt temperature, lower head pressure, and lower motor load. Additionally, the presence of talc reduces edge weave and neck-in during extrusion coating processes.
