Stretch wrap film and its method of production

1. A method of producing a reinforced stretch film comprising the steps of:

providing an elongated base sheet of plastic stretch film having a longitudinal axis;

forming a plurality of cord-like, elongated reinforcement members from a sheet of plastic stretch film other than the elongated base sheet;

forming a plurality of plastic film strip overlays from a sheet of plastic stretch film other than the elongated base sheet;

positioning the plurality of cord-like, elongated reinforcement members on the elongated base sheet where the cord-like, elongated reinforcement members extend along the longitudinal axis of the elongated base sheet;

positioning the plurality of plastic film strip overlay over each of the cord-like, elongated reinforcement members where the plastic film strip overlays are parallel and spaced from one another;

folding each edge of the elongated base sheet of plastic stretch film inward toward a center of the elongated base sheet creating a folded edge to further strengthen and reinforce each edge; and

sandwiching the cord-like, elongated reinforcement members between the elongated base sheet, the plastic film strip overlays and/or the folded edges;

attaching the plastic film strip overlays and the folded edges to the cord-like, elongated reinforcement members and to the elongated base sheet by:

holding the plastic film strip overlays and the folded edges onto the cord-like, elongated reinforcement members and to the elongated base sheet via static electricity;

laminating the plastic film strip overlays and the folded edges to the cord-like, elongated reinforcement members and to the elongated base sheet; and

sealing the plastic film strip overlays and the folded edges to the cord-like, elongated reinforcement members and to the elongated base sheet via a sonic welder;

whereby, the plastic film strip overlays and the cord-like, elongated reinforcement members define_elongated spaces therebetween.

2. The method of producing a reinforced stretch film of claim 1 wherein the step of forming a plurality of cord-like, elongated reinforcement members including randomly compressing a plurality of flat and narrow base plastic film strips by randomly compressing each of the flat and narrow, base plastic film strips by rotating a collector roll.

3. The method of producing a reinforced stretch film of claim 1 wherein the plurality of cord-like, elongated reinforcement members and the plurality of plastic film strip overlays are formed from a master material.

4. The method of producing a reinforced stretch film of claim 3 wherein the master material is slit by a slitter unit to provide base film strips of the plurality of cord-like, elongated reinforcement members, and the plurality of plastic film strip overlays.

5. The method of producing a reinforced stretch film of claim 3 wherein the master material is slit by a slitter unit at evenly spaced distances to provide base film strips of the plurality of cord-like, elongated reinforcement members and the plurality of plastic film strip overlays of equal widths.

6. The method of producing a reinforced stretch film of claim 1 wherein the step of positioning the plurality of cord-like, elongated reinforcement members to the elongated base sheet including attaching the plurality of cord-like, elongated reinforcement members to the elongated base sheet, where the cord-like, elongated reinforcement members are spaced from one another and disposed substantially parallel to one another.

7. The method of producing a reinforced stretch film of claim 6 wherein the step of positioning the plurality of cord-like, elongated reinforcement members to the elongated base sheet including attaching the plurality of cord-like, elongated reinforcement members to the elongated base sheet via a line of adhesive beads.

8. The method of producing a reinforced stretch film of claim 1 wherein the base sheet is uncovered in the elongated spaces therebetween each parallel, elongated reinforcement strip which includes a cord-like, elongated reinforcement member, a narrow plastic film strip overlay, and/or a folded edge.

9. The method of producing a reinforced stretch of claim 1 further comprising:

transporting the elongated base sheet in a direction of movement corresponding to the longitudinal axis of the elongated base sheet;

the step of forming a plurality of cord-like, elongated reinforcement members is completed simultaneously with the transport of the elongated base sheet;

where each of the cord-like, elongated reinforcement members is made by simultaneously randomly compressing the plurality of transported plastic film strips by randomly compressing each of the plastic film strip by simultaneously rotating a collector roll and employing a compressor nozzle during transport thereof;

the step of positioning the plurality of cord-like, elongated reinforcement members on the elongated base sheet being during transport of the elongated base sheet;

the step of folding over each edge of the elongated based sheet being during the transport of the elongated base sheet;

transporting the elongated base sheet and the cord-like, elongated reinforcement members attached thereto in the direction of movement to the longitudinal axis of the elongated base sheet; and

the step of attaching the plastic film strip overlays and the folded edges to the cord-like, elongated reinforcement members and to the elongated base sheet being during transport of the elongated base sheet and the cord-like, elongated reinforcement members attached thereto.
