Infrared and Hot Air Thermal Lamination
topic
Infrared heating and hot air lamination systems heat thermoplastic film or fabric surfaces to their melt temperature using radiant infrared panels or hot air impingement before combining with the second substrate in a pressure nip, enabling thermal bonding without the direct flame contact of flame lamination and providing more controllable and uniform heat distribution than open flame for heat-sensitive substrates requiring precise melt temperature control.
Role
Provides controlled thermal surface melting for adhesive-free lamination of heat-sensitive thermoplastic substrates where open flame would cause thermal damage or non-uniform heating, with infrared thermal lamination offering the precise temperature control advantage over flame lamination that enables processing of thin thermoplastic films and delicate nonwovens requiring narrow melt temperature windows without the surface quality variation from uneven flame-to-substrate distance in flame lamination.
