Abstract
Printable magnetic receptive composite sheets are made by calendering a thin layer of a magnetic composition and bonding it to a top printable layer on one or both sides of the magnetic layer wherein the calendered layer has a thickness up to 10 mils.
Claims21
A printable magnetic receptive composite sheet comprising:
- a calendered magnetic layer containing a thermoplastic binder and a magnetic material having a front side and a back side, and
- a printable top layer bonded to at least one of said sides, wherein said calendered magnetic layer has a thickness up to 10 mils.
A method of making a printable magnetic receptive composite sheet having multiple layers with a front and a back side comprising:
- calendering a thermoplastic composition containing a thermoplastic binder and a magnetic material into a continuous magnetic layer having a thickness up to 10 mils and;
- laminating a printable top layer onto at least one of said magnetic layer sides.
