Disposable absorbent product with coated element and related methods

A disposable absorbent product comprising:

• a hydrophilic topsheet defining an interior face of the disposable absorbent product configured to face a wearer thereof during use;
• a nonwoven backsheet overlaying said topsheet, said backsheet defining an exterior face of the disposable absorbent product configured to face away from the wearer during use;
• and
• an absorbent core disposed between said topsheet and said backsheet for storing fluid secreted by the wearer of the disposable absorbent product, wherein:
• said absorbent core includes at least one absorbent structure and a wrapping element enveloping said at least one absorbent structure, said wrapping element having a main substrate layer and an adhesive coating layer thereon, said adhesive coating layer defining an impermeable film layer on said main substrate layer, said adhesive coating layer is substantially adhered to said at least one absorbent structure,
• said adhesive coating layer is formed from a hot-melt adhesive, is tacky at room temperature, and has a basis weight of less than about 20 g/m2, and
• the disposable absorbent product is free of any impermeable barriers disposed between said bottom wall and said exterior face of the disposable absorbent product.

A method for forming an absorbent core for use in a disposable absorbent product, wherein the absorbent core is disposed between a backsheet and a topsheet overlaying one another, the method comprising:

• obtaining an absorbent structure primarily configured for storage of fluid secreted by a wearer of the disposable absorbent product;
• obtaining a main substrate layer;
• applying a coat of adhesive material onto the main substrate layer to thereby define an impermeable film layer on the main substrate layer;
• and
• enveloping the absorbent structure with the adhesive-coated main substrate layer so as to substantially adhere the coat of adhesive material to the absorbent structure, and to thereby define the absorbent core.
