Abstract
The present invention is directed to a novel process of making water-sensitive products. In addition, the present invention is directed to water-sensitive products, which maintain their integrity and strength when in use, but dissolve or disperse when place in contact with water, such as in a conventional toilet. Moreover, the present invention is directed to water-dispersible products, including flushable products such as release liners, product packaging, etc., which contain a water-sensitive film strategically coated with a discontinuous hydrophobic material to provide water protection to the film.
Claims22
A water-sensitive film having temporary protection from water comprising:
- a water-sensitive film;
- and
- a plurality of substantially discontinuous interengaged shapes of hydrophobic polymeric material on a surface of the water-sensitive film, the shapes having an average spacing between the shapes.
A water-sensitive film having temporary protection from water comprising:
- a water-sensitive film;
- and
- a plurality of substantially discontinuous interengaged shapes of hydrophobic material on a first surface of the water-sensitive film.
A water-sensitive film having temporary protection from water comprising:
- a water-sensitive film comprising polyethylene oxide, polypropylene oxide, ethylene oxide-propylene oxide copolymer, polyvinyl alcohol, or a combination thereof;
- and
- a plurality of substantially discontinuous interengaged shapes of hydrophobic material on a surface of the water-sensitive film;
- wherein the hydrophobic material comprises an amorphous polyolefin having a melt viscosity of about 400 to about 10,000 cps at 190° C.
