Most thermal laminating film consists of two layers: a base layer of polyester and an adhesive layer. The polyester layer forms the harder outer surface of the film and does not melt at laminating temperature. It provides rigidity and protection for your laminated items. The greater the polyester content, the higher the level of protection, rigidity, and luster.

The proportion of polyester and adhesive in a film is usually described with numbers. For example, a "1/2" film consists of one mil of polyester and two mils of adhesive. The first number refers to the base layer, which consists of polyester. The second number refers to the adhesive layer. A mil is 1/1000 of an inch.

The adhesive layer melts at the specified laminating temperature range and bonds the film onto the subject material under the pressure of the laminating rollers. Temperature setting will vary based upon laminating speed, source of heat (heat shoe vs. heated roller), thickness of media and room conditions. Typical temperature range for this film is 260° F - 290° F at a speed of 2-4 feet per minute.

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.
