A packaging material comprising a substrate layer, an intermediate layer, and a sealant layer, the intermediate layer comprising an intermediate layer substrate layer and a barrier coat layer containing a carboxylic acid polymer and a polyvalent metal compound, the intermediate layer being laminated so that the barrier coat layer is on a substrate layer side, all of the substrate layer, the intermediate layer substrate layer, and the sealant layer being polyolefin resin layers or polyester resin layers.

The present invention provides a recyclable laminate film structure comprising a separation layer coating. The separation layer coating facilitates separation of a selected polymer film during the recycling processing by selecting the polymer of the coating composition to have particular Hansen Solubility Parameters, so that the laminate structure delaminates at the layer of the coating, leaving clean pieces of the selected polymer film. In certain embodiments, the separation layer coating is a barrier coating, such as an oxygen barrier coating.

A method of individually packaging a single-use disposable diaper for use in intimate absorption of body fluid includes compressing a single-use disposable diaper for use in intimate absorption of body fluid from a first condition to a second, compressed condition, and retaining the single-use disposable diaper in the second, compressed condition with a pressure differential that acts upon a substantially flexible, substantially air impermeable material to maintain the single-use disposable diaper in the compressed condition. The pressure differential is created by locating the single-use disposable diaper in an interior space of a substantially air impermeable, substantially flexible material, creating a negative pressure within the interior space, and hermetically sealing the single-use disposable diaper at the negative pressure within the flexible material. The single-use disposable diaper is the only single-use disposable diaper contained within the hermetically sealed substantially air impermeable, substantially flexible material.
