The present invention refers to a versatile gas-barrier multilayer heat-shrinkable thermoplastic film that, by minimal variations in its manufacturing process, becomes suitable for the manufacture of packages, called Flowpack, on horizontal form-fill-seal (HFFS) machines, of tray-lidded packages or of shrinkable packaging bags. This film comprises a first outer sealant layer, a second outer polyester layer, an inner barrier layer, no polyamide or polyester inner layer(s), no polyolefin layers positioned between the barrier layer and the sealant layer and at least a polyolefin bulk layer of specific relative thickness placed between the inner barrier layer and the outer polyester layer.

Multilayer riblet applique and methods of producing the same are described herein. One disclosed example method includes applying a first high elongation polymer material to a web tool, where the web tool is to be provided from a first roll, and heating, via a first heating process, the first high elongation polymer material. The disclosed example method also includes applying a second high elongation polymer material to the first high elongation polymer material, and heating, via a second heating process, the second high elongation polymer material. The disclosed example method also includes applying, via a laminating roller, a support layer to the second high elongation polymer material.
