The maximum laminating speed provided by the device — in other words,
the length of the section that the laminator is able to laminate in a minute. The high speed rate makes it easier to operate with large volumes of media, but significantly affects the cost of the device. Therefore, it makes sense to look for a quick laminator only if you have to deal with large volumes of media, or if the ability to quickly handle the task is critical. If the device is bought for use from time to time, this indicator can be ignored.
Lamination type supported by the device.
—
Heated. During heated lamination, the media and the film are passed together through rollers or heating plates; while the adhesive layer inside the film is melted, it is fixed to the processed media. This method allows you to achieve good processing quality and reliable laminating, so, it is the most popular type of lamination so far.
—
Cold. Lamination type, where the media and film are sealed together only by the pressure of the rollers, without heating. This type is often used as an optionless step in cases where you have to work with heat-sensitive materials — for example, synthetics or glossy media. Note that specialized devices with only a cold lamination type are rare, and principally met among professional ones; much more often modern laminators support both cold and heated lamination types (see below).
— Heated and cold. Ability to operate with any type of described above. As usual, heated lamination is a regular option for such models, and for cold type, the heating element is simply turned off. Such devices are as versatile as possible, and their cost essentially do not differ from their heat-only analogues, and that's why the combined type is the most common for modern laminators.
