TECHNICAL FIELD OF THE INVENTION
The invention relates to method for transferring holographic design on a multilayer film, a method for manufacturing holographic multilayer sheet, and the holographic multilayer sheet thereof.
BACKGROUND OF THE INVENTION
Holographic films including metallized layers are known in the art and are utilized for a wide variety of applications. For example, flexible packaging substrates for food products, gift wrapping paper, as a decorative component in non-flexible packages or rigid packages in tubes of toothpaste, cereal boxes, detergent boxes, and the like. For many applications, and in particular in the packaging of food products, it is desirable that these metallized films have good oxygen and moisture barrier properties. Presently, the holographic sheets are manufactured by laminating holographic film of the PET (Poly Ethylene Terephthalate) or BOPP (Biaxially Oriented PolyPropylene). However, presently available holographic films have very low interlayer bonding strength against PET or BOPP interface, which may result into separation of the laminate layer from the metallized interface of the holographic multilayer sheet.
Moreover, PET or BOPP is considered as contamination in all Polyethylene multilayer tube laminate structure.
Therefore, there is need for a process that will create holographic design on pure polyethylene film and then bond the holographic, film excellently with the laminated sheets to be used for manufacturing attractive holographic tubes for food product, toothpaste, cosmetics etc.
SUMMARY OF THE INVENTION
An objective of the invention is to provide a method for transferring a holographic design on a multilayer polyethylene film having DSC (Differential Scanning Calorimeter) melting point less than or equal to 119 degrees centigrade.
Another objective of the invention is to provide a method for transferring a holographic design on a multilayer polyethylene film so that the holographic film has higher interlayer bond strength.
Yet another objective of the invention is to provide a method for transferring a holographic design enabling surface printing on the other side layer of the multilayer of the holographic film.
Yet another objective of the invention is to provide a method for manufacturing holographic multilayer sheet.
Yet another objective of the invention is to provide holographic films, which have good oxygen and moisture barrier properties.
Accordingly, the present invention provides a method for transferring a holographic design on a multilayer polyethylene film having DSC (Differential Scanning Calorimeter) melting point less than or equal to 119 degrees centigrade. The method comprises the steps of: embossing a holographic design over a PET (Poly Ethylene Terephthalate) or BOPP (Biaxially Oriented Poly • Propylene) film; metalizing the holographic design of the said film; preparing a multilayer having one side layer (herein after referred to as inner- side layer) with high metal affinity; applying adhesive in specific patterns over the surface of said inner side layer of the said multilayer film; adhering and curing holographic surface of the film over the adhesive applied surface of the
multilayer film; and separating PET c, SOPP film from the cured film wherein inner side layer in combination with adhesive firmly bond holographic portion.
Therefore the invention enables high interlayer bond strength and transferring of holographic design from the PET or BOPP film to the multilayer film. The invention further enables surface printing on the other side layer of the multilayer of the holographic film.
