| WHAT IS LAMINATION |
|
| Lamination refers to the process of bonding a clear plastic film onto printed matter. When the film hardens, its rigidity strengthens the durability of the print. In addition, the laminate also protects the print from stains, smudges, moisture, wrinkles or tears. It’s most often used on printed material that is expected to be used frequently, such as menus, signs, educational materials, bookmarks, etc.

SUMMARY
|
| THE PROCESS OF LAMINATING |
|
|
Lamination is achieved by using heat and/or pressure to bind the plastic to the print. Typically, the print is placed between two sheets of film, and both are pressed through either a heat or cold roll laminator.
Heated roll laminators will melt the glue that has been applied to the lamination film, which will seal the two films around the print. This is the most common method of lamination, as it is often lower-cost, has a high adhesion level, and is not affected by moisture during the application.This process is also called “thermal lamination”. Cold laminators rely on the film’s internal adhesive to stick to one another. This method is recommended when a print is sensitive to heat or has adhesion problems. In both processes, the print is put through two rollers to ensure a tight, smooth, and seamless look. This will protect the document or print on both sides, as well as along the edges. The number of rollers involved can also affect the quality of the lamination. 2-roller machines are the most economical, and are often found in smaller laminators found in homes or offices. 4 rollers are more consistent and thorough, while 6-roller machines are often used for photo quality artwork with bubble-free lamination. The more rollers a machine has, the more likely it can provide a consistent and even heat distribution. Most laminators protect both sides of a document or print. While single-side lamination is also achievable, it is more difficult to do and less common to find. |

| BENEFITS OF LAMINATION |

There are many benefits to laminating print. Some include:

| LAMINATE THICKNESSES, FINISHES AND EDGES |
|
|
Laminate film can come in a variety of thickness, finishes and edges. Their thickness is measured in mils, which is the same as 1/1000ths of an inch (not to be confused with millimetres). Therefore, a laminate film that is 1.5mil would be 0.0015” thick after it’s been pressed. Commonly, laminate films run in the following thicknesses:
When purchasing a laminating machine, make sure the film thickness is compatible with your machine! Laminating finishes also come in a variety of sheen levels. They can come in gloss, satin/lustre, or matte, but the most common options are gloss and matte.
With lamination, you can also have a sealed edge or a flush edge. Each as it’s own pros and cons.

Laminates come in all sorts of thicknesses and sheens. In the example above, the business cards are laminated with a sealed edge.

| HOME / OFFICE LAMINATORS |
|
| Laminators come in all shapes and sizes. The most commonly used laminator for home and office tends to be the pouch laminator. Pouch laminators are used to laminate smaller objects, usually ranging from small ID cards to large documents that may be poster-size. The “pouch” is made up of two laminating films that are attached on one side, making it easy to slide the document in and fit it between the laminating sheets. These pouches come in a variety of pre-cut sizes in order to cut down waste and trimming time. Due to the higher polyester-to-adhesive balance in laminating pouches, they also feel heavier and stiffer than laminating film. |  An example of a desktop office laminator. |
| INDUSTRIAL GRADE LAMINATORS |
|
|
Often, printing companies will use roll laminators as their method of laminating. Industrial-sized roll laminators are designed for high quality, high volume laminating, and are capable of laminating large sizes - from large documents to outdoor posters or banners.
Roll laminators usually use two rolls of laminating film - one above the feed tray, and one below it. The print is placed on the feed tray and gently pushed towards the laminator. The rollers pull the document along with the film. The print re-appears on the other side of the machine fully laminated, and often requires a bit of trimming along the edges. The greatest benefit of laminating film is their versatility. They can come in various finishes, weights and thickness, such as (but limited to) matte, matte UV, gloss, etc. Lighter films are especially excellent for large, artistic displays, as they can be nearly undetectable with the naked eye.

| OPINIONS ON LAMINATION |
|
|
When used for offices, crafts, and home, usually lamination is well-received. Its rigid surface provides protection and its glossy surface usually deepens and enhances the print. However, for the same reason, lamination can sometimes be viewed as cheap and tacky when used outside of a functional purpose.
That being said, laminates can still be found in the art world. Plaque mountings, for example, are all finished with a matte laminate on top in order to protect the poster or certificate from damage and moisture. Because the film is a softer and matte, it is hardly noticeable, and thus appears more timeless. With the edges of the print also sealed alongside the wood, there is less risk that the laminate will be “opened”, as the wood would also have to be cut to break the bond. This all helps with the print’s protection, as well as showcasing its true colors without reflective interference.
