Definitions

  • the present invention relates to a flexible anti-shock and/or anti-scratch sheet and which protects against atmospheric agents and from oxidation and corrosion.
  • the object of the present invention is to provide a sheet which can be used to wrap materials or products in order to protect them from the type of deterioration described above.
  • the sheet 2 of the invention includes a smooth surface 4 and a corrugated surface 6 having corrugations 8.
  • the sheet of the invention is produced by heat extrusion and the material used can therefore be for example polyethylene, nylon, polypropylene, PVC, polystyrene, etc. and mixtures thereof, or in any case a plastics material which can be heat extruded.
  • the sheet of the invention is manufactured as follows; the material which is being used is melted in the fusion chamber of an extruder, not shown, and is then heat-extruded at a temperature between 60°C and 350°C, in dependence on the material being used.
  • the material is in the form of a smooth sheet; while it is still hot it is passed between a flat surface and a surface which is the negative of the desired shape of the surface of the finished sheet. Once it has passed through the forming surfaces, the product is cooled and then rolled up or cut to specific sizes of sheets.
  • the manufacturing method could involve the use of self-expanding or heat-expanding resins or other steam-based processes in order to achieve a product which is expanded, by a percentage which could be varied, thereby making the sheet lighter and reducing costs at the same time.
  • the sheet could be either single layered or bonded to a layer of a paper, plant, mineral, plastics, metal or synthetic material, thereby strengthening the product or altering the consistency thereof.
  • Corrosion inhibitors or other inhibitors operable to prevent problems caused by humidity, condensation, sunlight, or either high or low temperatures may be provided; the sheet could also be produced with additives providing protection in the event of contact with chemical agents, oil, grease, soap, solvents, varnishes and the like.
  • the surfaces or sides 4 and 6 could both be corrugated.
