a) Dry bonding lamination
b) Solventless lamination
c) Extrusion lamination
d) Wet bonding lamination
Answer: c
Explanation: Extrusion lamination doesn’t require an adhesive for lamination. It causes adhesion by heat and pressure during the process of extrusion. Dry and wet bonding lamination used aqueous or solvent based adhesives. Solventless lamination uses a curing agent for adhesion.
