Understanding When to Use Pressure Sensitive Film

Although thermal lamination provides excellent protection for documents, it is not suitable for some surfaces. Many inks, thermal printed paper, some types of artwork, and photographic paper can all be damaged by the high temperatures that thermal lamination requires. For these items, cold, or ‘pressure sensitive’ lamination, is the answer.

Like thermal lamination, cold lamination provides excellent protection against dust, dirt, handling, friction and moisture. But unlike thermal lamination film, Pressure sensitive film bonds using a self-adhesive coating which is activated when the film passes through the laminating machine’s rollers. The adhesive is pressed against the document being laminated, excluding air and forming a permanent bond between the film and document. The fact that it relies on pressure rather than heat can result in a slightly lower standard of coverage, but carried out properly the difference in quality is minimal.  

Pressure sensitive film is available in all the normal size, core and length combinations that thermal film comes in, and in a wide range of finishes from the ever popular glossy film to lustre, matte and textured finishes. It also comes with both solvent and aqueous based adhesives, and with varying degrees of UV protection, depending on whether it will be used indoors or outdoors. Pressure sensitive film is manufactured using a variety of synthetic bases, including environmentally biodegradable film.
