Hot Stamping Foil & Heat-transfer Material

Author:Ivan Zhang
For the flat-to-roller and flat-to-flat processes,only hot stamping foil  is employed.but,for roller-to-flat and rotary processes,hot stamping foil is not only used,but also heat-transfer material is consumed.Foil and heat-transfer material's structure is described as below.

1.Backing Film
Foil and heat-transfer material built on the backing film,PET,are both the multi-layer structure.As for PET backing film,it characterizes as stable size,even surface tension and good resistance to high temperature,ect.

2.Release Agent
Release agent is in a solid state under some temperature,with some adhesion ability,and up to some temperature,release agent,oiled substance,becomes melt.It,actually,functions as the adhesion buffer between PET layer and transfer layer/printing layer.Usually,it's the silicon resin with low viscosity and is coated on the PET film by a gravure press or coaters.

3.Aluminum Layer/Graphic Layer
Usually,the film,printed by a gravure press,is the graphic layer of heat-transfer material,and the layer,created by the process of vacuum aluminum vaporized,is the aluminum layer of the foil.The difference between foil and heat-transfer material is how to produce this layer.No matter foil or heat-transfer material,they are both sensitive to the high temperature.
Heat-transfer is usually used to decorate the plastic objects and produce a vivid graphic.For the foil,is primarily used to create the metal luster and provide the objects with a value-added effect.

4.Adhesive Layer
The top layer of foil and heat-transfer material,is a layer of adhesive.According to the different substrates,the different adhesive is coated on the aluminum layer/graphic layer.If adhesive matchs the substrate,the good adhesion is achieved after decorated
