Technical Examples

An engraving sheet includes a support layer fabricated of biaxially oriented high-density polypropylene, and an engraving layer formed on the support layer and having an opacity of 40%. The engraving sheet is engraved from the engraving layer down to the support layer. The support layer is lower in opacity than the engraving layer with a difference of 20% or more between the opacity of the support layer and the opacity of the engraving layer. The engraving sheet allows a desired pattern, a photograph of the face of an individual, or the like to be engraved thereon, and presents a finger touch similar to that of paper, and is hard to be torn even after it is bound by a sewing machine or a stapler.
