<p>A method for providing single units of sugarless chewing gum and compositions so packaged. Individual pieces of chewing gum are provided which units will have a sufficiently long shelf life in order to allow the units to be sold and carried by a consumer even in environments that are detrimental to the stability of chewing gum, e.g., high temperature and humidity. To this end, a piece of chewing gum is provided that is substantially sugar free and that is surrounded by a wrapper, with at least a first portion of the wrapper being sealed to a second portion of the wrapper to create a sealed environment that houses the piece of chewing gum. The wrapper has a moisture vapor permeation rate of less than 0.10 g/100 in2/24 hr at 100 degree F, 90 percent RH as measured by ASTM method F1249-90. In an embodiment, the wrapper has an oxygen permeability that is less than 0.10 cc/100 in2/24 hr at 1 ATM as measured by ASTM method D3985-81.</p> |
