Cold laminating films are a distinct category of laminating film from thermal films, and work on a very different basis. Whereas thermal films use heat to melt a layer of plastic onto the surface of the item being laminated, cold films use a layer of contact adhesive. This used to lead cold films (also known as ‘pressure sensitive films) to be renowned for air bubbles and an imperfect finish. Thankfully, those days are long gone, and cold films today use superb adhesives that give perfect clarity yet form a strong bond. Combined with a synthetic base, a good cold film will last for years indoors or outdoors.
There are many advantages to using cold film rather than thermal film. Cold film is cost effective, and perfectly suited to use with graphics. Thanks to the fact that they don’t need heat to laminate, they will not damage coloured inks as thermal film often will.
cold thermal films are waterproof, dust proof, highly flexible, and durable. They are also available in a range of finishes, making them suitable for almost any purpose.
A further advantage of cold films is their ease of use in portable situations. Since they do not require heat, and therefore electricity, it is possible to buy portable lamination machines that are ideal for use on the go.
