Abstract
A casing for ham and sausage, has a cubic design and provides a buffer effect. Characters and other patterns are embossed on the casing surface. The characters and patterns are made using heat foamed ink, on one surface of a film to be pasted together with another film. The films each have a heat shrinkable property and together form the casing.
Claims13
A casing for use in enclosing ham and sausage, comprising a heat shrinkable base film having an inner surface and an outer surface, a surface film having an inner surface adhered to said outer surface of said base film, a pattern of heat foamable ink forming an inner pattern between said outer surface of said base film and said inner surface of said surface films, said inner pattern being provided on one of said inner surfaces of said surface film and said outer surface of said base film whereby heating of said casing causes shrinkage of said shrinkable base film and expansion of said heat foamable ink to form a textured pattern on said outer surfaces corresponding to said pattern of foamable ink.
A method of forming a casing for ham and sausage comprising printing a pattern using heat foamable ink onto an inner surface of surface film, applying a bonding agent onto the inner surface of the surface film over the heat foamable ink, attaching a heat shrinkable base film over the bonding agent to adhere the base film to the surface film and heating the base film, surface film and heat foamable ink to shrink the base film and to expand the heat foamable ink to form a three dimensional pattern on outer surfaces of the base and surface film.
A method according to 7, including forming the pattern using crossing straight lines to form a string net pattern.
A casing for use in enclosing ham, and sausage, comprising:
- a heat shrinkable base having an inner surface and outer surface;
- a bonding material adjacent said outer surface of said heat shrinkable base film;
- a heat shrinkable surface film having an inner surface adhere to said outer surface of said base film by said bonding material;
- a pattern of heat foamable ink forming an inner pattern between said outer surface of said base film and said inner surface of said surface film, said inner pattern being provided on one of said inner surface of said surface film and said outer surface of said base film whereby heating of said casing causes shrinkage of said shrinkable base film and shrinkage of said shrinkable surface film and expansion of said heat foamable ink to form a textured pattern on said outer surface corresponding to said pattern of said foamable ink.
