Lamination is the technique of manufacturing a material in multiple layers, so that the composite material achieves improved strength, stability, appearance or other properties from the use of differing materials. A laminate is usually permanently assembled by heat, pressure, welding, or adhesives. Laminating film encapsulates the item completely by being bonded to both its sides.
Lamination technology is a technology for layering a variety of functional polymer films or layers of a substance, such as wood or textiles, and bonding them with resin, adhesive or bonding agents to form a finished product. Laminated board, for example, consists of thin layers of wood bonded together; similarly, laminated fabric consists of two or more layers of cloth joined together with an adhesive, or a layer of fabric bonded to a plastic sheet.
Lamination techniques include dry and wet types, roll-to-roll continuous lamination and one-by-one sheet batch lamination. These form the platform technologies for the manufacture of adhesive-related products, polarizing films and other optical products, flexible printed circuit and other electronics-related products, air filters, and other products. In recent years, the lamination products market has offered more advanced requirements for thin-layer, visual appearance, and product precision responding with technology development for more sophisticated operations.
Until now, urea and PVAc glues have been mainly used to lamination furniture surfaces with finishing films.
#Types of laminators
Pouch laminating machines
Pouch laminating machines are meant for home use or moderately if used in the office. These are inexpensive machines and are quite effective.
Also known as pouch laminators, in these machines a lamination pouch is used which is generally affixed on one side. A heat-activated film lines the inside of the lamination pouch which adheres to the item being laminated as it is run through the laminating
