Hot Melt Adhesive for Bookbinding & Print Finishing
In bookbinding and print finishing, hot melt adhesive does two jobs: it locks the spine (spine glue) and secures the cover (side glue). The right adhesive keeps pages from loosening on the shelf and gives a clean, professional finish without oozing through the paper.
Spine Glue vs Side Glue
- Spine glue — bonds the book block to the spine; needs enough flexibility to survive opening and closing
- Side glue — attaches the cover; needs clean set and appearance
What Drives the Choice
- Paper type — coated, uncoated, coated-one-side all behave differently
- Binding equipment — perfect binder temperature and speed set the window
- End use — library, promo, or lay-flat each have different durability needs
Recommended Approach
Confirm your paper weight, binder model and line speed, then evaluate a matching EVA or specialized grade. View hot melt granules →
FAQ
What temperature is used for bookbinding hot melt?
Most EVA bookbinding grades apply in the 120–150°C range, but the exact setpoint is confirmed against your binder. Reference general-purpose sticks such as 103A run at 120–150°C.
Can one adhesive do both spine and side glue?
Sometimes, but many lines use different formulations for spine flexibility and side appearance. Tell us your equipment to recommend the right combination.
How do I avoid pages falling out?
Match the adhesive to paper type and binder temperature, and validate with a sample run before bulk production. Surface preparation of the spine also matters.
