Stretch wrap film and its method of production

Reinforced stretch film comprising:

• an elongated base sheet of plastic stretch film having a longitudinal axis;
• and
• a plurality of elongated reinforcement strips extending along the longitudinal axis of the elongated base sheet, disposed substantially parallel to one another, and defining elongated spaces therebetween;
• each elongated reinforcement strip comprising:
• a cord-like, elongated reinforcement member made from a sheet of plastic stretch film other than the elongated base sheet attached to the elongated base sheet and extending along the longitudinal axis of the elongated base sheet;
• and
• a narrow plastic film strip overlay made from a sheet of plastic stretch film other than the elongated base sheet positioned over the cord-like, elongated reinforcement member;
• where, the narrow plastic film strip overlays are attached to the cord-like, elongated reinforcement member and to the elongated base sheet at opposed sides of the cord-like, elongated reinforcement member to fixedly sandwich the cord-like, elongated reinforcement member between the elongated base sheet and narrow plastic film strip overlays;
• where each edge of the elongated base sheet of plastic stretch film is folded inward, and over at least one cord-like, elongated reinforcement member creating a folded edge to further strengthen and reinforce each edge;
• and
• where, each edge of the elongated base sheet is attached to the cord-like, elongated reinforcement member and to the elongated base sheet to fixedly sandwich the cord-like, elongated reinforcement member between the elongated base sheet and folded edge.

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
• attaching the plastic film strip overlays and/or the folded edges to the cord-like, elongated reinforcement members and to the elongated base sheet to fixedly sandwich the cord-like, elongated reinforcement members between the elongated base sheet, the narrow plastic film strip overlays and/or the folded edges;
• whereby, the narrow plastic film strip overlays and the cord-like, elongated reinforcement members comprising parallel, elongated reinforcement strips defining elongated spaces therebetween.
