Overview: Letter-Size Laminating Pouches (9″ x 11 ½”)
Friday, March 11th, 2011
Letter-size laminating pouches are by far the most common and popular pouch size used by our customers. There are many good reasons for the popularity. There are also a few things you should know about this popular size prior to making a purchase. I will provide some valuable tips in this article that will help you get the most out of our letter-size pouches.
A letter-size laminating pouch is naturally the most popular size used by pouch laminator owners for several reasons. For one, letter-size paper is the most common paper size used with printers. Letter-size paper can be used to print cards, signs, book covers, business cards and more.
You may have noticed, by the title of this article, that letter-size laminating pouches measure in at 9″ x 11 ½” (23 cm x 30 cm). The reason these pouches are slightly larger than a letter-size sheet of paper (8 ½” x 11″) is to provide a tight seal around the document being laminated and to provide a little alignment room.
Laminating pouches are sealed along a single edge, making the two sides of the pouch into a folder. This seal takes up about 1/8″ of the film. Once a letter-size document has been laminated, you generally have about a ¼” clear plastic border around the entire document. This excess can be left as is or it can be cut off using a paper cutter.
Once laminated, a letter-size pouch can easily be cut down into smaller documents. Many of our customers will use a printer to create a 10-up or 12-up business card pattern (using an 8 ½” x 11″ sheet of paper) and then laminate it using a letter-size laminating pouch after. Finally they cut the individual business cards out using a rotary paper cutter. The end results look great.
Cutting a laminating pouch does not cause the laminated document to fall apart, however, it will expose around the edges the laminated document. This may cause the document to peel apart over time.
Ultimately, once cut, a laminated pouch is only as strong as the material the film is bound to. Leaving a laminated edge around a document will improve its water resistance and long-term integrity.
You should also be aware that letter-size laminating pouches come in different thicknesses. At this time we currently offer pouches in a 3, 5, 7 and 10 mil thickness. The higher the number, the thicker the pouch. A mil is a thousandth of an inch. You can read more about everything involved in the thickness of a pouch here.

Old film probably won’t adhere to inkjet or fuser oil based output because they are the most difficult types of output to stick to. Most traditionally printed output is much easier to stick to so old film may work fine on it for several years. I still use Glenroy pouches, which are at least 8 years old, and they work fine on my black & white laser printer output, newspaper articles and even traditional photographs.
