Abstract

A sheet product package and method of making discrete plastic sheets includes a package enclosure with a dispensing opening structure and a plurality of discrete plastic sheets arranged in a stack. The plurality of discrete plastic sheets are disposed within the package enclosure, and each of the plurality of discrete plastic sheets is electrostatically charged. In the method of making the dispensable plastic sheets, electrostatically charged discrete plastic sheets are formed and arranged in a stack. The method may include forming a continuous plastic film, cutting the continuous plastic film into discrete plastic sheets, and, after cutting, electrostatically charging the discrete plastic sheets.

First claim

What is claim is:

1. A sheet product package, the sheet product package comprising:
a package enclosure, the package enclosure including a dispensing opening structure; and
a plurality of discrete plastic sheets arranged in a stack, the plurality of discrete plastic sheets being disposed within the package enclosure, wherein each of the plurality of discrete plastic sheets is electrostatically charged, and wherein the discrete plastic sheets are comprised of a polyolefin material.

2. A sheet product package as set forth in claim 1 , wherein each of the plurality of discrete plastic sheets is electrostatically charged in a range from 3 KV to 20 KV.

3. A sheet product package as set forth in claim 1 , wherein the plurality of discrete plastic sheets includes a first set of discrete plastic sheets and a second set of discrete plastic sheets and wherein the first and second sets of discrete plastic sheets are interleaved such that the sheets from the first set of discrete plastic sheets and sheets from the second set of discrete plastic sheets alternate along the stack.

4. A sheet product package as set forth in claim 3 , wherein the first and second sets of discrete plastic sheets are interfolded.

5. A sheet product package as set forth in claim 4 , wherein each of the discrete plastic sheets has an inward facing side and an outward facing side.

6. A sheet product package as set forth in claim 5 , wherein the inward facing sides of the discrete plastic sheets in the first set of discrete plastic sheets are bonded to the inward facing sides of the discrete plastic sheets in the second set of discrete plastic sheets by electrostatic charge and the outward facing sides are loosely stacked.

7. A sheet product package as set forth in claim 1 , wherein the dispensing opening structure is configured to define an elongate opening having a length extending along a longitudinal axis, wherein each of the plurality of discrete plastic sheets has a length along the longitudinal axis, and wherein the length of the dispensing opening is 70-98% of the length of each of the plurality of discrete plastic sheets.
