A two-part epoxy glue is the most common type of food-safe glue used. It consists of two separate parts, a resin and a hardener, that need to be mixed before application. It dries to form an extremely tight bond and is nontoxic. These glues are made from materials considered food-safe by the FDA. They have a high tensile strength and a good shear strength, are resistant to moisture, oil and solvents, and work in a wide range of environments.
