Bostik PES 680V Soft Touch Flexible Copolyester Hot Melt

Bostik PES 680V Copolyester Glue for Flexible, Soft Touch Film Laminations

Bostik PES 680V is a high-performance elastic copolyester adhesive specifically designed for flexible bonding and soft touch film applications. With a low Shore D hardness of 30 and a glass transition temperature of –22°F (–30°C), it enables durable yet flexible adhesion to sensitive substrates. PES 680V’s thermal range of 284–338°F (140–170°C) and smooth processing behavior make it ideal for engineered laminates requiring softness, stretch, and resilience. It also supports soft touch finishes commonly used in premium packaging and technical films.

Features of Bostik PES 680V Soft Touch Copolyester Hot Melt Glue
