Abstract

A protective wrap for use in packaging and shipping includes a plurality of flexible material strips whose length and width may be varied as well as the selected material and a plurality of relatively rigid material strips whose length would typically be the same length as the flexible material strips but whose width will vary depending upon the application. A suitable material for the relatively rigid material strips is corrugated paper or expanded polystyrene foam. The flexible material strips and the relatively rigid material strips are arranged side by side in alternating sequence and when a backing layer is not used, the strips are joined to each other by adhesive. When a backing layer is used the strips may either be joined together by adhesive or joined by adhesive directly to the backing layer. While both materials may provide suitable protection for the article being packaged and shipped, the flexible material strips allow the wrap to be shaped and conformed to the product while the rigid material strips provide strength and rigidity also for protection as well as for strength in carton stacking.
