Abstract
A holographic flexible tube laminate for packaging and a method of making the same. A flexible laminate substrate applied with an adhesive layer has a metalised holographic embossed pattern transferred onto the adhesive layer. The holographic side of the laminate substrate is further optionally applied with corona treatment, printed and applied with a protective transparent material coating. The edges of the laminate substrate without the adhesive layer are lap joined by heat sealing to form the tube laminate.
Claims15
A holographic flexible tube laminate for packaging, the tube laminate comprising a flexible laminate substrate applied with an adhesive layer on one outer surface thereof leaving out the edges thereof and having a metalised holographic embossed pattern transferred onto the adhesive layer, the holographic side of the laminate substrate being further applied with corona treatment optionally, printed and applied with a protective transparent material coating comprising ultraviolet curing varnish, the laminate substrate being folded into a tube with the protective material coating side of the laminate substrate forming the outside of the tube and the edges of the laminate substrate without the adhesive layer being lap joined by heat sealing to form the tube laminate.
A method of making a holographic flexible tube laminate for packaging, the method comprising the steps of:
- (i) transferring a metalised holographic embossed pattern onto an adhesive layer applied on one outer surface of a flexible laminate substrate leaving out the edges of the laminate substrate;
- (ii) optionally giving corona treatment to the holographic side of the laminate substrate;
- (iii) printing the holographic side of the laminate substrate;
- (vi) applying a protective transparent material coating comprising ultraviolet curing varnish on the printed side of the laminate substrate;
- and
- (vii) forming the laminate substrate into a tube with the protective material coating side of the laminate substrate being the outer side of the tube and lap joining the edges of the laminate substrate by heat sealing.
