Abstract
The current invention utilizes an extrusion coating method as a key step in a series of multilayer construction processes to make a laminate for graphic application. The extrusion coated layer performs as a strengthening layer to provide mechanical properties for the construction, while an ink receptive coating layer delivers high quality printability performance. High gloss can be achieved through the use of a PET carrier.
Claims15
A process for making a graphics film comprising the following steps:
- a. coating and drying an ink receptive layer onto a carrier web,
- b. extrusion coating a polyolefin material onto the ink receptive layer of step (a),
- c. removing the carrier web from the ink receptive layer to expose a surface of the ink receptive layer.
