What is Dry Gum Paper
Adhesive
Dry Particle Gummed (DPG) adhesive is dry to the touch and activates only when moistened.
Handling
Clean and easy to process; no sticky residue during printing, stacking, or converting
Applications
Labels, envelopes, filing systems, archival uses, packaging, and crafts.
Recyclability
All-paper construction with no silicone liners—simplifies repulping and recycling.
What is Wet Gum Paper
Adhesive
Already tacky or slightly moist adhesive that stays “wet” to the touch.
Handling
Requires protective liners or wax interleaving to prevent sheets from sticking together.
Applications
High-speed labeling machines, specialized packaging lines, and certain legacy equipment.
Recyclability
May include additional liners or coatings, making disposal and recycling less straightforward.
