Drytac's MHL™ laminating films are specially developed for multi-heat laminators (MHL) and hot-shoe laminators. These high quality laminating/encapsulating films are coextruded (see diagram) to a carefully balanced ratio of polyester film versus adhesive. The result is higher clarity for more vibrant colors, reduced "orange peel," greater rigidity (which reduces wrinkles and waves) and better adhesive flow characteristics (wet out).
Note: Film-to-adhesive ratio is an important indicator of quality. (The higher the polyester content, the higher the quality of the film.) Ratio is designated by the mil of film over the mil of adhesive. For example: Drytac's 5.0 mil (125 micron) film is a 3:2 (75:50) film consisting of 3.0 mil (75 micron) of film coated with 2.0 mil (50 micron) of adhesive.
MHL laminating films are available in a variety of thicknesses and finishes, from standard gloss and luster finishes to scratch-resistant films suitable for outdoor applications. All Drytac MHL films are suitable for both single-sided and double-sided laminating (encapsulation) of photographic, electrostatic, inkjet-bond, xerographic and lithographic output as well as many more applications. These films also incorporate UV absorbers for excellent protection from damaging UV rays.
Tips for applying Drytac MHL™ Thermal Films
- Consider webbing your laminator with a gloss on top and a luster on the bottom supply shaft. This will allow you to change finish by feeding in your image face up or face down.
- Use your idler bar to increase the area of contact between the heated rollers and the film.
- To allow for proper heat recovery, laminators with a smaller diameter roller require a slower processing speed and/or higher operating temperature for the best results.
- MHL laminating films bond while they are cooling (thermoplastic). This means that it is important that you create a steady uniform tension with the pull rollers (and a cooling system for thicker films) to ensure a smooth, flat encapsulated print without waves or wrinkles.
