In 1962, GBC purchased Virginia Laminating, a designer and manufacturer of lamination machines. Typical converting processes include coating, laminating and printing. Melamine-formaldehyde resins are used for plastic laminating. The foam was then covered in a high-strength laminating fabric and epoxy-resin. General Binding Corporation (GBC) supplies machines and material for binding documents, laminating, and displaying products. PCTFE is also used for laminating other polymers like PVC, polypropylene, PETG, APET etc. Laminating a plastic film is also a method of providing wet strength. In North America, the material providing the laminations is termed "laminating stock" or "lamstock". For laminating process, vinyl ester is usually initiated with methyl ethyl ketone peroxide. Yet another explanation is the characteristics of the wood from a time before laminating techniques. Microcrystalline waxes can generally be put into two categories&colon; "laminating" grades and "hardening" grades. It can be used for casting and laminating. This process was referred to as "laminating" or "Damascus". The plans, along with ideas for "laminating timber", lighthouses, and draining islands, all survive.
