BUY Laminating Rolls & Laminating Pouches
 
Definition: a sheet of material made by bonding two or more sheets or layers. The process consists of "sandwiching" a cell between sheets of clear plastic laminate in an effort to preserve it.
There are two basic ways to laminate. The first is to use pouch lamination. This process requires the use of a clear plastic laminate that is sealed on one side and the document is placed inside this laminating pouch. It is then run through a laminating machine that applies heat and pressure to seal the pouch. There are several different sizes of laminating pouches ranging from the small business card sizes to the larger legal size and menu pouches. Pouch lamination comes in a variety of thicknesses measured in millimeters. Some of the most common mils for pouch lamination are 3,5,7 and 10 mil. 3 mil is the thinnest stock and 10 mil is a stronger lamination with a thicker and harder shell. Coastal Business Supplies offers a wide variety of sizes and mil's. If you can't find what you are looking for don't hesitate to contact a sales rep and let them do the legwork for you.
Another form of lamination is called "roll lamination". Our laminating rolls are composed of a perfect blend of polyester and adhesive, which results in smooth, clear lamination. You won't find any scrap material or 2nds being used to make our laminating rolls. Coastal Business Supplies only offers the best lamination quality available and at the best price. Roll lamination is a process that involves two laminating rolls, a top and a bottom roll, and is placed on the machine with the glue sides facing each other. As the rolls are "uncoiled" a document is placed between the two pieces of laminate and are sealed as they travel through the rollers and the heat is applied. It is important to leave a small edge around the document to allow the lamination to adhere to itself. Some form of trimming is usually required with roll lamination. This lamination process is generally used for larger volume items as it can run at higher speeds and in a continuous roll. Again, Coastal Business Supplies offers a wide variety of Roll laminating in 3, 5, 7, and 10 mil thicknesses and the friendly sales staff would be more than happy to help find supplies for your custom laminating needs.
Principles of (heat shoe) Roll Laminating:
Roll laminators operate by pulling film with a thermally-activated adhesive over a heat source and into a set of laminating rollers. Film from a film supply roll passes over heat shoes to activate a polyethylene adhesive layer on the film. It then passes through rubber rollers to apply pressure and bond the film with the item being laminated. The film will actually fuse into the item.
What is Laminating Film:
Most thermal laminating film consists of two layers: a base layer of polyester and an adhesive layer of polyethylene. The polyester layer forms the harder outer surface of the film and does not melt at laminating temperature. It provies rigidity and protection for your laminated items. The greater the polyester content, the higher the level of protection, rigidity and luster. The polyethylene layer melts at laminating temperature and bonds the film onto the subject material under the pressure of the laminating rollers. As and X-test demonstrates, the adhesive is pressed into the paper and fills irregularities in the surface.
The proportion of polyester and polyethylene in a film is usually described with numbers. For example, a "1-2" film consists of one mil of polyester and two mils of polyethylene. The first number refers to the base layer, which consists of polyester in the majority of thermal films. The second number refers to the adhesive layer, which is usually polyethylene. A mil is 1/1000 of an inch
Since polyester is the more costly of the two types of plastic generally used in laminating film, a "2-1" film will cost more than a "1-2" film. Both are 3 mil films, but the "2-1" version will seem a little thicker on a piece of laminated material because it will be slightly stiffer
In the U.S. laminating trade, the generally accepted practice is to describe two-sided lamination, or encapsulation, by the thickness of one layer of film. For example, "3-mil lamination" should refer to lamination with two layers of 3-mil film. If you are buying or selling laminating film or lamination services, please make sure both parties understand the film descripitons being used.
There is a huge variety of thermal laminating films available to suit many different kinds of application. Here are some of the more commonly used "special" film types of film additives:
Film with low-melt adhesives; these often have better clarity and are less lilely to curl or ripple when laminating conditions are not ideal - often called copolymer.
Matte surfaces to eliminate glare, or matte surfaces that will accept printing or writing; many suppliers offer films with both glossy and matte (non-glare finishes).
Film with UV inhibitors to prevent film deterioration in sunlight and protect colors in the laminated material from fading.
Opaque or colored films for the back side of a lamination; these can form a border for a laminating piece.
Iridescent clear films for special visual effects.
Permanently waterproof films for outdoor, underwater or special applications; the most common thermal laminating films are mde with water-based primers and will eventually de-laminated if continually exposed to water or wather; truly waterproof films are made with special printers.
Low Melt Film:
What is low melt? A copolymer film, meaning there are two adhesives (instead of just polyethylene), which act synergistically. (Greater in total effect than the sum of their effects, example: 2+2=9). These activate at lower temperatures.
Advantages of low melt film:
Adheres aggressively
Increases production by being run faster because the adhesives activate at lower temperatures
Good for difficult to laminate substances, for example: polished, coated, smooth or non-porous surfaces.
What is photocoat? Low melt film designed to laminate photographs.
What is UV (ultra violet) film? The film has UV inhibitors to prevent film deterioration in sunlight and protect colors in the laminated material from fading. This will not prevent color such as red from eventually fading if in direct sunlight.
