Substrate with integrated multi-layer pouch/pocket

A method of sealing a used diaper within a foldable diaper changing mat comprising the steps of:

• placing the used diaper within a bottom edge facing pocket or a top edge facing pocket of the foldable diaper changing mat to form a diaper containing pocket, wherein the foldable diaper changing mat comprises:
• a base layer having a surface engaging side and an upward facing, infant engaging side and a top edge and a bottom edge;
• an infant head receiving pad portion;
• and
• an infant buttocks receiving pad portion having a top end facing the top edge of the base layer and a bottom end facing the bottom edge of the base layer, wherein the infant buttocks receiving pad portion is engaged with the upward facing, infant engaging side and proximate the bottom edge of the base layer and wherein the infant buttocks receiving pad portion has at least one intermediate layer and a top, absorbent-containing layer, wherein the base layer, the at least one intermediate layer and the top, absorbent-containing layer are engaged with one another so as to create the top edge facing pocket and the bottom edge facing pocket that are different pockets and separated from one another;
• reaching on the outside of the diaper containing pocket to physically grasp the used diaper without directly physically touching the diaper;
• and
• inverting the foldable diaper changing mat by flipping the foldable diaper changing mat inside out a first time to form a single inverted diaper containing mat.

A foldable diaper changing mat comprising:

• a foldable base layer having a surface engaging side and an upward facing side and a top edge and a bottom edge;
• an infant head receiving pad portion engaged with the upward facing side;
• and
• an infant buttocks receiving pad portion having a top end that faces the top edge of the foldable base layer and a bottom end that faces the bottom edge of the foldable base layer, wherein the infant buttocks receiving pad portion is engaged with the upward facing side and proximate the bottom edge of the foldable base layer and wherein the infant buttocks receiving pad portion comprises a first intermediate layer, a second intermediate layer, and a top absorbent-containing layer and wherein the foldable base layer, the first intermediate layer, the second intermediate layer and the top, absorbent-containing layer are sealed so as to create a top edge facing pocket and a bottom edge facing pocket that are separated from one another and do not share any of the same internal volume.
