Are there any Poly based materials that can run on the Epson P20570?

We are using paper-based photo papers on our Epson P 20570 printer. We "sandwich" the print between two sheets of acrylic (mount the print to an acrylic sheet then mount another acrylic sheet to the back of the print) We've had some failures with the photo paper separating/coming apart with this product.

Looking for an alternative to paper-based photo paper. Any suggestions would be appreciated.
