Printable snap-breakable sheet

Abstract

A card sheet including a top material having punched lines, the front side of the top material being printable. A carrier material of at least one polymer layer is directly applied as by extruding to the back side of the top material. The polymer has a stress-at-break in the range of 10 to 30 MPa and an elongation at break in the range of 10 to 120%. From the card sheet individual cards may be broken out to form high quality calling (business) cards, photograph cards, post cards or the like.

         152 . A printable sheet comprising: 
 a polymer film sheet;    cut lines penetrating a partial thickness of the printable sheet and defining perimeter edges of subdivided sheets;    the printable sheet having a printable surface; and    the polymer film sheet having elongation-at-break and stress-at-break properties such that after the printable sheet has been passed through a printer or copier and a printing operation conducted on the printable surface, the printable sheet snap-breaks along the die cut lines when the printable sheet is folded on the lines to form individual printed subdivided sheets.
