Food-safe wood glue is made for kitchen woodworking projects like cutting boards, salad bowls, spoons, and serving trays. Once fully cured, this glue does not leak harmful chemicals into food. That makes it safe for daily chopping, washing, and serving.
Woodworkers use food-safe glue to build strong joints that handle moisture, heat, and wood movement without cracking. It gives peace of mind when food touches the surface every day.
What Makes Wood Glue Food Safe?
A glue is food safe only after it fully cures. True food-safe glue meets FDA CFR 175.105 rules for indirect food contact. This means lab tests confirm no chemicals move into food.
Important points:
- Safe only after curing
- No taste, smell, or toxins
- Forms a hard, sealed barrier
- Tested with water, acids, and oils
“Non-toxic” alone is not enough. Always check the label or safety data sheet.
