TH10550B - Foil and method of foil making - Google Patents

Abstract

Foil for use related to food wrapping Cosmetics and other products which have a plastic base layer on which one side is coated with a film of organic material. For example, aluminum provides the exposed surface of the metallic film with a thin protective layer. It is composed of waxes, resins, lubricants and/or other organic materials and will protect the metallic layer from abrasion, abrasion, corrosion as well as from direct exposure to air and/or moisture. It vaporizes the film's organic material on one side of the base layer. and will vaporize the organic material of the protective layer on the exposed surface of the film in one or more steps as soon as the vaporization of the organic material on the increments of the base layer has been completed.

Claims (24)

1. A foil with two surfaces of foil that are relatively parallel in a planar plane, on which at least one surface is provided a metallic layer (2), on which the metallic surface is unaffected by the metallic layer, which covers the entire surface of the foil, of the characteristic that the layer is in the form of a protective layer (3) which is firmly attached to the metallic surface and which is composed of organic products and is vaporized onto the metallic surface immediately after the application of the metallic layer (2) within the installation of the metallic layer before the mechanical loading of the metallic surface, where the organic products have a high affinity for the metallic layer (2) since the vaporization and strong adhesion to the aforementioned. 2. A foil of claim 1 characterized by the organic product having a molecular weight of at least 10,000 kP. 3. A foil to claim clause 2, characterized by the synthetic resin being in the form of a lacquer resin. 4. A foil of claim 1 characterized by the organic product being in the form of a synthetic wax with a molecular weight less than 10,000 kP. 5. Foil of claim 1, characterized by the organic product being in the form of natural resin. 6. Foils of any one of the claims 1 through 5, which are characterized by the organic product being in the form of a printing base to facilitate printing onto a metal surface. 7. The foil of any one of claims 1 through 6 is of the characteristic that the protective layer (3) is applied very thinly. 8. The foil of any of the claims 1 through 7 is of the characteristic that the protective layer (3) is covered on an unscratched metal surface (6). 9. Any foil of claims 1 through 8 is of the characteristic that the protective layer (3) has corrosion-resistant properties to protect the metal layer (2) from corrosion. 10. Any foil of claims 1 through 9 is characterized by the protective layer (3) being a layer resistant to blocking. 11. Foil of any one of the claims 1 through 10 which is characterized by the printable protective layer (3). 12. The foil of any of the claims 1 through 11 is characterized by the provision of a protective layer (3) for lining. 13. Any foil of claims 1 through 12 is of the characteristic that the protective layer (3) receives a material which has a uniform extrusion and which is crystallized on such layer. 14. Any foil of claims 1 through 13 is characterized by the protective layer (3) being ergonomically acceptable. 15. The foil of any one of the claims 1 through 14 is characterized by the protective layer (3) being odorless. 16. Foil of any one of the claims 1 through 15, which is characterized by having polypropylene as a carrier material (1) 17. Foil of any of the claims 1 through 15, which is characterized by having polyester as a carrier material (1) 18. Any foil of claims 1 through 17 is of the characteristic that its protective layer (3) strengthens the top metal layer (2) facing it to such an extent that it has high abrasion resistance. 19. The process for fabricating a protective layer for the metal layer (2) which is vaporized and embedded onto the foil, whereby the metal surfaces adjacent to the foil are covered by a protective layer (3), is characterized by the fact that the protective layer (3) is made of an organic product which is vaporized and embedded onto the metal layer (2) immediately after vaporization and embedding onto the metal layer (2). Within the metallization fixture used for pre-metallization of the metal layer (2), a mechanical load is applied in which the organic product is vaporized with high affinity for the metal layer (2) and firmly adheres to it. 20. The process under claim 19 is characterized by the fact that when a layer of natural resin organic material is applied to the metal surface (6) of the metal layer (2) immediately after the vaporization of the metal layer (2), before the foil covering the metal layer is rolled up. 21. The process under any of the claims 19 to 20 is characterized by the application of a very thin layer of organic material. 22. Any of the processes under claims 19 to 21 is characterized by the organic material layer being directly deposited onto the metal layer (2) from at least one heated vaporizer (19), in which the vaporized organic material (22) is fed at a velocity corresponding to the vaporization velocity into which the metal layer (2) is deposited onto the carrier material (1). 23. The process under claim 22 is characterized by the vaporizer (19) being electrically heated over its surface. 24. Any of the processes under claims 19 through 23 are characterized by the fact that resin material (22) is vaporized on a metal layer (2) when an organic material layer is combined with resin (23) which is vaporized in a vaporizer (19).
