In our study, we replaced traditional adhesives with compounds made with recycled plastic shopping bags in order to make hot-melt plywood using various amounts of plastic film, different hot-pressing temperatures and hot-pressing times.All three variables have an effect on the intensity and water-resistance of plywood.The results show that the bonding strength of plywood does not increase with increasing amounts of plastic film.When the hot-pressing temperature is increased to 150°C, the bonding strength does not necessarily increase any further.At a hot-pressing time of 6 min, the bonding strength reaches a maximum, after which it will decrease.The optimum hot-pressing parameters are as follows:100 g·m-2 of recycled plastic, a hot-pressing temperature of 150°C and a hot-pressing time of 6 min.This study puts forward a new idea of making use of plastic waste, which, ultimately, may solve the problem of formaldehyde emission without damaging the environment.It has enormous potential market applications.
