A method for making a disposable package for an agent, typically water, activatable substance includes providing a planar support member of a moisture and air barrier material, mounting on the support member a sheet at least in part translucent, sealing all but one edge of the sheet to the support member to provide a pocket fixed to the support member, placing the agent activatable substance in the pocket so as to occupy only a portion of the pocket, folding the support member and pocket upon themselves, and releasably sealing overlying portions of the support member together along all but a folded edge of the support member, to enclose the agent activatable substance, whereby to provide a package which is openable by separating the overlying portions to expose the pocket for introduction of the agent into the pocket to activate the agent activatable substance therein.

1. A method for making a disposable package for an agent activatable substance, the method comprising the steps of:providing a substantially planar support member of a moisture and air barrier material;mounting on a major surface of the support member a sheet at least in part translucent, the sheet being mounted within all boundaries of the support member surface;sealing all but one edge of the sheet to the support member to provide a pocket fixed to the support member;placing the agent activatable substance in the pocket so as to occupy only a portion of the pocket;folding the support member and pocket upon themselves; andreleasably sealing overlying portions of the support member together along all but a folded edge of the support member to enclose the agent activatable substance;whereby to provide a package which is openable by separating the overlying portions to expose the pocket for introduction of an activating agent into the pocket to activate the agent activatable substance therein,wherein the step of providing the support member comprises providing a foil-based, opaque support member, andwherein the step of sealing the sheet edges to the support member comprises heat such that the sheet is hermetically sealed to the support member. 2. The method in accordance with claim 1 wherein the agent is a fluid. 3. The method in accordance with claim 1 wherein the agent is water. 4. The method in accordance with claim 1 wherein the support member is an opaque, high-barrier polymer. 5. The method in accordance with claim 1 wherein at least one of the support member and the sheet of the pocket is provided with activating agent fill level indicia thereon and observable to an operator. 6. A disposable package for an agent activatable substance, the package comprising:a substantially planar support member of a moisture and air barrier material;a sheet of material, at least in part translucent, mounted on the support member for forming a pocket, the pocket being open along one side thereof;an agent activatable substance disposed in the pocket and occupying only a portion of the pocket;said support member and the pocket being folded upon themselves, said support member being releasably sealed along all overlying edge portions, other than a folded edge;whereby to provide a package which is openable by separating the overlying releasably sealed edge portions to expose the pocket open side for introduction of an activating agent into the pocket for activating said agent activatable substance, andwherein the pocket is hermetically sealed to said support member and said support member is hermetically sealed to itself along the overlying edges thereof, other than the folded edge. 7. The package in accordance with claim 6 wherein said support member comprises a flexible foil-based support member. 8. The package in accordance with claim 7 wherein said foil-based support member is opaque. 9. The package in accordance with claim 7 wherein said support member is provided with notches which facilitate tearing of said support member along a line substantially parallel to and spaced from a bottom of the pocket. 10. The package in accordance with claim 9 wherein the notches facilitate the tearing to render the package openable by the separating of opposite overlying sealed edge portion of the package, such that the package is openable without use of a cutting device and without compromising integrity of the package. 11. The package in accordance with claim 6 wherein at least one of said support member and said sheet of the pocket is provided with an agent fill level indicia thereon and observable to a user. 12. The package in accordance with claim 11 wherein the agent fill indicia are disposed on said support member and observable through translucent portions of the pocket. 13. The package in accordance with claim 6 wherein said agent is a fluid. 14. The package in accordance with claim 6 wherein said agent is water. 15. The package in accordance w ith claim 6, wherein said support member is an opaque, high-barrier polymer.
