Abstract: A biodegradable bioplastic may be formed from starch or cellulose. A carbohydrate may be reacted with chloroacetamide and further reacted with one or more cross-linking agents to obtain a bioplastic material. The bioplastic material may be insoluble in water, and/or hydrophobic and/or substantially transparent. The bioplastic material may be formed into numerous shapes and structures. The bioplastic material may have high toughness, flexibility and/or moldability whereby the material is suitable for further processing into a wide variety of different shapes and structures. The bioplastic material may also be utilized as a barrier or coating on paper or other substrates for food packaging and other applications.

Abstract: Two-component epoxy-based liquid formulations and their resultant dual use epoxy-based products. The epoxy-based liquid formulations include a liquid epoxy resin composition mixed with a liquid epoxy curing agent composition. The liquid epoxy resin compositions include one or more liquid epoxy resins containing a reactive oxirane structure or epoxide group, while the liquid epoxy curing agent composition comprises one or more epoxy curing agents. The liquid epoxy resin and liquid epoxy curing agent compositions are mixed together to provide a dual functioning epoxy-based formulation that, when applied to a substrate and cured, provides a cured three-dimensional cross-linked thermoset dual acting epoxy-based product having both the moisture vapor barrier and the primer functionalities.

Abstract: Barrier films are prepared from a blend of two high density polyethylene blend components and a high performance organic nucleating agent. The two high density polyethylene blend components have substantially different melt indices. Large reductions in the moisture vapor transmission rate of the film are observed in the presence of the nucleating agent when the melt indices of the two blend components have a ratio of greater than 10/1. The resulting barrier films are suitable for the preparation of packaging for dry foods such as crackers and breakfast cereals.
