Abstract

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 is provided. The holographic film has higher interlayer bond strength against PET (polyethyleneterephthalate) or BOPP (Biaxially oriented polypropylene) enabling surface printing on the other side layer of the multilayer of the holographic film. The films have good oxygen and moisture barrier properties and therefore can be used be used for manufacturing attractive holographic tubes for food product, toothpaste, cosmetics etc.

Claims

AMENDED CLAIMS received by the International Bureau on 16 November 2009 (16.11.2009)CLAIMS:
1. A method for transferring a holographic design on a multilayer thermoplastic copolymer film, the method comprising: a. embossing the holographic design over a film; b. metalizing the holographic design of the said film; c. preparing a multilayer film having a inner side layer with high metal affinity; d. applying adhesive over the surface of the inner side layer of the said multilayer film , wherein the adhesive is applied in a predetermined pattern; and e. adhering and curing holographic surface of the film over the adhesive applied surface of the multilayer film.
2. The method according to claim 1 , wherein the multilayer sheet is produced by co- extrusion blown process, the multilayer sheet having a haze value of less than and equal to nine and thickness between forty and sixty micron.
3. The method according to claim 1 further comprising the step of separating the film from the cured film, the inner side layer in combination with adhesive firmly bonding with the holographic portion.
4. The method according to claim 1, Wherein. the multilayer thermoplastic copolymer film has a DSC (Differential Scanning Calorimeter) melting point from 98 to 105 degrees centigrade.
5. The method according to claim 1 , wherein the design is embossed over a PET (Poly Ethylene Terephthalate) or BOPP (BIAXIALLY ORIENTED POLY PROPYLENE) film.
6. The method according to claim 1 , wherein the step of curing is carried out for a duration of 48 to 72 hours.
AMENDED SHEET (ARTICLE 19) 8
7. The method according to claim 1 , wherein the step of curing is carried out at a temperature between 45 and 550C.
8. The method according to claim 1 , wherein the application of adhesive over the surface of the inner side layer of the said multilayer thermoplastic co-polymer film in a predetermined pattern includes applying adhesive at some parts over the surface of the inner side layer depending upon the predetermined pattern.
