Abstract
The present invention is directed to a novel laminate used in the production of a food or other consumer package and having a light energy emitting printed or image fields as well as other printed or imaged fields, which emit no light energy. The laminate of the present invention prevents direct contact by such light emitting material with the contents of the particular package with which it is associated as well as the user of the particular package. The laminate may be used integrally as part of the package or may be applied directly to an external surface of a preformed package.
Claims19
A laminate to be used in connection with a retail package, comprising:
- at least first and second layers, with one of said first and second layers having first and second surfaces, at least one of said first and second surfaces capable of receiving printing;
- a binder disposed between said first and second layers to secure said first and second layers one to another;
- said one of said first and second surfaces capable of receiving printing and having first and second printable areas;
- said first printable area being imaged with an alpha-numeric pattern and said second printable area being imaged with a non-alpha-numeric pattern;
- and
- wherein at least one the patterns of one of said first and second areas being printed with an ink having visible light energy emitting properties.
A food package, comprising;
- a laminate having first and second layers, each of said layers having first and second sides;
- a first region of one of said first and second sides of said first and second layers being receptive to a first printing, said first printing being confined to a first area;
- a second region of one of said first and second sides of said first and second layers being receptive to a second printing different than said first printing, said second printing being confined to a second area distinct from but complimentary to said first area;
- one of said first and second printings having a light energy emitting property;
- and
- wherein said first area is substantially confined within said second area.
A method of printing a printable surface of a film, comprising;
- providing a film having first and second surfaces and first and second end edges and first and second longitudinally extending sides;
- printing on at least one of said first and second surfaces in a direction parallel to said longitudinally extending sides;
- producing a first set of images having a first property on said one of said first and second sides;
- creating a second set of images having a second property different from said first property on one of said first and second sides;
- and
- applying light energy to each of said first and second set of images such that only one of said first and second properties absorbs the light energy such that only one of said first and second sets of images emits said light energy producing a visible set of images.
