Aluminium Foil Laminating consists basically of combining a web or sheet of aluminum foil with one or more other materials, such as paper and plastic films, using Plastic Extrusion bonding. The resulting product is a sandwich of three or more layers, e.g., foil/ Plastic Extrusion material /and another material. For the most part, aluminum foil is laminated on web-fed, rotary equipment. which also frequently includes a coating unit for coloring or otherwise pre-coating the aluminum foil.
The laminating process requires that the rolls of foil and other material be unwound and that a controlled application of Plastic Extrusion material like PE be applied to one or the other, or occasionally to both of these webs. This combination of foil, Plastic Extrusion material, and other material is then brought together when it passes through the nip of the combining rolls; (Usually one steel and one rubber roll). These apply just enough pressure to marry the materials into a single web.
Frequently, one or more Laminations are also applied to the foil side, to the film or paper side, or to both sides of the lamination. This may be done in-line where practical, or subsequent to combining. Such coatings are typically decorative, protective, or are priming or anchor & coatings for printing inks or other converting materials. Thus, the converter is able to color or otherwise coat the web at the same time he laminates it, achieving the obvious economies of performing two or more operations at once or in one pass through the machine or line.
Most modern aluminum foil laminating machines are built on this unit, or station, principle. A five unit arrangement is common, with unit variations depending upon the particular process. The basic five are two unwind units; Plastic Extrusion applicator / Extrusion die / Plastic extruder ; a combiner or pressure rolls; and a rewind. Additional units often included are another coater and a dryer. Some laminators also include combining rolls after the drying unit for laminations made by applying the adhesive to a web and drying it before combining the materials. From the standpoint of the types of main methods of laminating aluminum foil.
Extrusion bonding combining is done simultaneously with application of hot adhesive; in this case, the hot plastic, such as polyethylene, which is deposited from an extrusion die located at the combining roll nip, formed by a rubber and a steel roll. The steel roll is chilled to affect the bond by setting or solidifying the plastic quickly.
Many of the principal aluminum foil uses and markets, and a number of specialty applications, have been mentioned in connection with discussions ofvarious properties or converting operations in other sections of this book. But the versatility of aluminum foil and the literally hundreds of ways in which it is used in commerce throughout the world, demand more comprehensive listing of end uses.
An excellent condensation of major aluminum foil applications is afforded by the converted and nonconverted foil end-use many classifications. These are used for the aluminum foil end-use report compiled annually by the U.S. Department of Commerce. Presented on the pages that follow, is an overview of the many kinds of specific types of aluminum foil packages and other products.
The basic categories in which all statistically identifiable aluminum foil applications are reported by the Aluminum Association to indicate industry shipments are as follows:
