Abstract

A wipe formed of a base layer and a secondary layer. The wipe has an initial caliper of at least about 0.5 mm, a basis weight of less than about 55 gsm and a % DIB of about 20-95%. The base layer is formed of a non-biodegradable material such as thermoplastic polymer and the secondary layer is formed of a biodegradable material such as wood pulp, cellulose and/or regenerated cellulose. The top surface of the secondary layer generally includes a non-uniform distribution of fibers.

Claims

1. A wipe comprising a base layer and a secondary layer, said wipe having an initial caliper of at least about 0.5 mm and a % DIB of at least about 20%, said base layer at least partially formed of non-biodegradable material, said secondary layer at least partially formed of biodegradable material, said base layer and said secondary layer including different materials.

2. The wipe as defined in claim 1, wherein said base layer includes a majority weight percent of thermoplastic polymer material, a majority weight percent of said base layer including non-biodegradable material, said secondary layer includes a majority weight percent of one or more materials selected from the group consisting of wood pulp, cellulose, regenerated cellulose, cotton, and biodegradable polymer, a majority weight percent of said secondary layer including biodegradable material.

3. The wipe as defined in claim 1, wherein said wipe has a basis weight of less than about 55 gsm.

4. The wipe as defined in claim 1, wherein said wipe has a final caliper, a ratio of said final caliper to said initial caliper of said wipe is about 1.25-20:

1.

5. The wipe as defined in claim 1, wherein said base layer and said secondary layer have an initial thickness, a ratio of said thickness of said base layer to said secondary layer is about 1-4:

1.

6. The wipe as defined in claim 1, wherein said base layer and said secondary layer have an initial weight, a ratio of said weight of said secondary layer to said base layer is about 1-9:

1.

7. The wipe as defined in claim 1, wherein said secondary layer includes a non-uniform distribution of non-woven fibers in a top surface of said secondary layer.

8. A wipe comprising a base layer and a secondary layer, said wipe having an initial caliper and a final caliper, a basis weight of about 50-110 gsm and a % DIB of about 20-95%, said initial caliper about 0.5-6.5 mm, a ratio of said final caliper to said initial caliper is about 1.3-10:

1, a majority weight percent of said base layer formed of a non-biodegradable material, a majority weight percent of said secondary layer formed of a biodegradable material, said base layer and said secondary layer including different materials, said secondary layer including one or more materials selected from the group consisting of wood pulp, cellulose, regenerated cellulose, cotton, and biodegradable polymer, said base layer including thermoplastic polymer material.
