The tobacco formulation includes granular tobacco and a buffer comprised of sodium carbonate and sodium bicarbonate. An outer packaging material enveloping the pouch is provided and is sealed so as to allow a controlled environment to be maintained within.

An atomic layer deposition system and method utilizing radicals generated from a high-density mixed plasma for deposition is disclosed. A high-quality oxide or oxynitride can be deposited by exposing a substrate to a first precursor which is adsorbed onto the substrate during a first phase of one deposition cycle. After purging the deposition chamber, the substrate is exposed to a second precursor which includes oxygen radicals and krypton ions formed from the high-density mixed plasma. The ions and radicals are formed by introducing a radical generating feed gas (e.g., O₂) and an ion generating feed gas into a plasma chamber and exciting the gases to form the high-density mixed plasma. The radicals and ions are then introduced to the substrate where they react with the first precursor to deposit a layer of the desired film. Krypton is preferably used as the ion generating feed gas because the metastable states of krypton lead to an efficient dissociation of oxygen into oxygen radicals when compared with other inert gases.

A composition such as a water-based consumer product comprises material (e.g. perfume) encapsulated within shell capsules, each capsule comprising an encapsulating wall having an inner surface and an outer surface, with a coating on the inner surface and/or outer surface of the shell wall, the composition further comprising surfactant and/or solvent. The coating can improve the barrier properties of the shell and can enhance retention of the encapsulated materials within the shell.

A composite multi-layer barrier is produced by first vapor depositing a barrier under vacuum over a substrate of interest and then depositing an additional barrier at atmospheric pressure in a preferably thermoplastic layer. The resulting multi-layer barrier is then used to coat an article of interest in a lamination process wherein the thermoplastic layer is fused onto itself and the surface of the article. The vacuum-deposited barrier may consists of a first leveling polymer layer followed by an inorganic barrier material sputtered over the leveling layer and of an additional polymeric layer flash evaporated, deposited, and cured under vacuum. The thermoplastic polymeric layer is then deposited by extrusion, drawdown or roll coating at atmospheric pressure. The resulting multi-layer barrier may be stacked using the thermoplastic layer as bonding agent. Nano-particles may be included in the thermoplastic layer to improve the barrier properties of the structure. A desiccant material may also be included or added as a separate layer.

Disclosed are oxygen-scavenging polymer compositions having high transparency and low haze comprising immiscible blends of at least one polyester comprising 2,2,4,4-tetramethyl-1,3-cyclobutanediol, a copolyamide or a transamidized, homogeneous blend of a least two polyamides, and a metal catalyst. The components of the immiscible blend which have refractive indices which differ by about 0.006 to about −0.0006. The small difference in the refractive indices enable the incorporation of regrind into the polymer composition to produce transparent shaped articles. The blends of the present invention are useful in producing shaped articles such as, for example, sheeting, films, tubes, bottles, preforms and profiles. These articles may have one or more layers and can exhibit improved excellent barrier properties and good melt processability while retaining excellent mechanical properties.
