The adhesives used in composite packaging are mostly polyurethane, which is made of polyhydroxy chemical substances and alicyclic isocyanate polymers, and the residual alicyclic acrylate reactivity rate is hydrolyzed and converted into futuramide.” Fructamide is such a harmful substance, and it will cause environmental pollution if it is transferred into the food category.
