Abstract
Sealed liquid tissue is comprised of a length of tissue and a layer of waterproof film. The layer of waterproof film has at least one pocket filled with liquid. The layer of waterproof film is attached to the top surface of the tissue. The bottom surface of the waterproof film is configured so that it has less resistance to bursting under hand pressure than the top surface of the film. Hand pressure applied to the film is capable of causing the bottom surface of the film surrounding the pocket to burst while the top surface of the film remains intact. This causes the liquid within the at least one pocket to escape through the bottom surface of the film to moisturize the length of tissue, thereby forming a wet wipe like article which has a wet lower surface and a dry upper surface.
