ABSTRACT:
The stratiform product in sheet form for packaging purposes comprises at least one impact-resistant film, made e.g., from a closed-cell foamed polyethylene, and a layer constituted by an elastomeric mass endowed with properties of selective and repetitive adhesion. Between this impact-resistant film and the layer of elastomeric mass, a support for this latter layer can be provided, which is constituted, e.g., by a non-woven fabric or by a plastic film. The product for packaging purposes protects the packaged articles against the impacts and the environmental agents, keeps said packaged articles fixed in a predetermined relative position and makes it possible inspections and/or checks to be carried out, with the initial integrity of the package being subsequently restored.
