is tpu hot melt adhesive film harmful to the body?

the reason why traditional glues are not environmentally friendly is that their ingredients contain toxic and harmful substances, such as formaldehyde, or they require the use of some toxic and harmful solvents to achieve viscosity. then we will analyze from these two points. first, the component of tpu hot melt adhesive film is tpu (polyurethane), which is a safe and harmless component. secondly, tpu hot melt adhesive film becomes sticky after heating and is thermoplastic. adhesives do not use organic solvents, so from these two points, we can conclude that tpu hot melt adhesive film is environmentally friendly and harmless to the body.

the tpu hot-melt adhesive film goes through a high-temperature melting process during the production process. this process can promote the volatilization of some harmful substances and ensure that its ingredients are safer. when the hot-melt adhesive film is reused in products or material composites, even if it is used again even in a "high temperature" environment, no other harmful substances will volatilize. therefore, after these two high-temperature processes, it is ensured that the tpu hot melt adhesive film is a completely non-toxic and harmless environmentally friendly adhesive.
