The important thing is to be aware of the differences so you can make an informed decision. Here is a discussion of the major differences between the two types. Obviously the major difference is in the use of heat. Cold lamination doesn't come with this risk and may be better for use around children.
Power requirements. Cold laminators use pressure sensitive adhesive to coat items. Heat laminators have the advantage when it comes to pouch size variety. As with anything using heat, there is always the risk of accidental burn injuries when using a hot laminator.
Overall, the choice between cold and hot lamination depends entirely on what is best for your office. But the way they work boils down to either hot or cold lamination. However, because cold laminators don't need to warm up and are ready to use instantly, they complete the job faster. Between the different brands, widths, materials used, and features offered, the choices are numerous. Before you choose a laminator for your office, be sure you know what materials you will be laminating so you can get the right machine for your specific needs. The supplies available for heat laminating with these options are severely limited, especially in petite sizes. Supplies for cold lamination are more expensive than their hot counterparts.
Laminators are made in a wide range of sizes and with a variety of features. Heat sensitive items, including vinyl, most photos, and thermally sensitive materials (like those used for ultrasound images) should use cold lamination to avoid heat damage due to their low melting temperatures. One final difference is the غير مجاز مي باشدt. However, cold laminators have the edge in adhesion methods. Many heated machines offer insulation and other preventative features to counteract this risk.
Speed. Actual processing speed tends to run about the same with both machines. Cold machines have the option to laminate and apply adhesive, apply adhesive only, or laminate with matte adhesive. This gives them the advantage of being transported for use anywhere. For many offices, the advantages of cold lamination may outweigh the extra غير مجاز مي باشدt of the supplies needed.

Heat. Hot laminators require anywhere from two to fifteen minutes to heat up before they even begin to process anything. Both methods have their own advantages and weak points. Heat also affects what can be laminated. But the غير مجاز مي باشدt of supplies can have a wide variation. Because cold laminators don't need to heat up, many smaller models don't even need to be plugged in. Hot laminators will always need an electrical outlet in order to be used. Each method has its own strengths and weaknesses and the better choice often depends on your needs.
The outside surfaces can heat up enough to cause damage to sensitive skin. While many items work fine with hot lamination, cold is better for others. There is a large selection of laminating pouches for heated machines while cold laminators have limited options. Overall, these machines generally run similarly in price
