Abstract
A process for producing an adhesive-free laminate is described herein. The process includes printing an ink on a surface of a first film, exposure of the printed film to UV radiation such that the ink is at least partially cured, contacting the first film to a second film such that the ink is between the first and second film, and exposing the combination of the first film, the ink and the second film to a second UV radiation. It has been found that this process can produce a high-quality laminate, without the presence of an adhesive.
Claims20
A process to produce an adhesive-free laminate comprising,
- a printing a UV radiation sensitive ink on a surface of a first film;
- b exposing the first film and the UV radiation sensitive ink to a first UV radiation;
- c contacting the first film to a second film such that the UV radiation sensitive ink is between the first film and the second film and the UV radiation sensitive ink is in direct contact with a surface of the second film, resulting in a combination of the first film, the UV radiation sensitive ink and the second film;
- and
- d exposing the combination of the first film, the UV radiation sensitive ink and the second film to a second UV radiation.
A process to produce an adhesive-free laminate comprising:
- a a first step of printing a UV radiation sensitive ink on a surface of a first film;
- b a second step of exposing the first film to a first UV radiation;
- c a third step of contacting the first film to a second film such that the UV radiation sensitive ink is between the first film and the second film and the UV radiation sensitive ink is in direct contact with a surface of the second film, the third step resulting in a combination of the first film, the UV radiation sensitive ink and the second film;
- and
- d a fourth step of exposing the combination of the first film, the UV radiation sensitive ink and the second film to a second UV radiation.
