Film layers made from formulated polymer compositions are disclosed. Film layers made from such formulated compositions have surprisingly good (for example, low) water vapor transmission rates and are particularly useful for packaging dry goods such as cereal. The polymer compositions preferably have at least one homogeneous ethylene homopolymer and at least one heterogeneously branched ethylene polymer. The homogeneous ethylene homopolymer has a molecular weight much higher than that of the heterogeneously branched ethylene polymer, although the density of each is preferably higher than about 0.95 g/cm.

Film layers made from polymer formulations

The present invention relates generally to synthesis of radioactive material, such as a tritiated polymer, and an apparatus for generating electrical current from the nuclear decay process of a radioactive material. In one embodiment, the invention relates to an energy cell (e.g., a battery) for generating electrical current derived from particle emissions occurring within a radioactive material such as a tritiated polymer) on pore walls of a porous semiconductor. The radioactive material may be introduced into the energy cell by a wetting process.
