13 inch(33CM)single sided laminators are great for laminating shops and small print shops,this is good for small quantity using.A single side laminator is the perfect way for high quality single side lamination of flyers, book covers, posters and so on.
Now it is possible to do one-sided lamination on an ordinary two-sided laminator. Obviously some material has to be used in place of one of the films: Kraft Paper can be used; it will stick to the film but can be trimmed off and discarded. Or, two rolls of single-sided lamination film can be used, with two items at once being placed back-to-back to be run through; they must be pretty well exactly the same size. But a problem here is that the laminations will almost certainly curl: single-sided laminators have special design features to take care of this, but using a "Lay Flat" nylon film will help.
Anti -curling metal adjustable bar will be a good solution for the curl situation .
