Dry lamination
Dry lamination is also well known as thermal lamination or heat lamination. Some time back lamination process was carried out by wet adhesives and was known as wet lamination. Significance of dry lamination is absence of any laminating adhesive in liquid form. Only heat is needed to make laminate.

Dry lamination process
Dry laminating films are produced by coextrusion process. One base film like BOPP, PET or Nylon is used to support the heat sensitive laminating adhesive usually thylene vinyl acetate. Laminating adhesive is applied under pressure and sudden temperature drop. It is also works to increase the glossyness of the film. Dry lamination film is then treated for corona to make it printable otherwise it can not be useful to adher colors.

Critical properties
Since dry lamination is used to make laminates, its most critical property is bonding strength with the media. Corona treatment level is needed to develop better bond strength. Some other properties are as below.
 * GSM
 * Yield
 * CT dyne level
 * Haze
 * Gloss
 * Shrinkage
 * Bond strength
 * COF
 * Green bond
