4. LAMINATUR OPERATING INSTRUCTIONS MODELS GBC4120 GBC4180 ween wwe mn INTRODUCTION These instructions describe the use and function of two 2 laminators which despite their varying widths are similar in appearance and performance FILM WIDTH 12 30 cm 18 46 cm MODELS GBC4120 GBC4180 GBC Laminators apply coated transparent film to one but usually both sides of documents photographs or any sheet like material GBC laminating film consists of a polyester film coated one side with polyethylene heat reactivatible adhesive The film is applied by heat and pressure with the adhesive contacting the product to be laminated In the process the adhesive adheres to the product and the end result is a laminate whose appearance is enhanced and resistance to damage is greatly increased Laminating Hints 1 Always run test samples before laminating valuable products or documents to insure proper laminator performance Feed product to be laminated slowly and evenly into heat roll nip with machine running Employ side guide Once product is engaged by the heat rolls it is committed Make no attempt to alter product position while in motion except to hold it taut from trailing edge Wrinkles in laminated product usually are caused by attempts to straighten product which has already been engaged Do not force product between heat rolls If product does not enter heat roll
5. ROLL BOTTOM FILM GUIDE ATTACHED TO FEED TABLE FIG 4 Theory of Successful Laminating To obtain the ultimate in a successful laminate three factors should be present 1 The product to be laminated should be receptive to and capable of attaining a good bond with molten polyethylene adhesive Most paper products can be laminated with a high degree of integrity This is because molten polyethylene cements to individual fibers of the paper surface The rougher the surface texture the more fibers are exposed to adhesive and the better the bond between adhesive and prod uct Many substances are applied to paper prod ucts which impair bond between fibers and the molten adhesive Clay and ink affect this bond While good adhesion occurs between molten adhesive and ink or clay poor adhesion may exist between ink or clay and its parent paper Accordingly the lamination process will be adequate but the overall laminate may lack some integrity oome paper and card stocks are coated with silicones wax or varnish which inhibit the ability of molten polyethylene to stick tightly to indi vidual paper fibers In such cases a superficial bond develops which may be adequate depend ing upon intended use of the finished laminate omooth surfaces especially photographic metallic and plastic are difficult for polyethylene to bond to since no fibers are exposed for the adhesive to contact Again a superficial bond
