“…Polyethylene terephthalate (PET) is one of the commonly used types which is distinguished by good properties of strength, durability and cheapness as well as availability in the surrounding environment [11,12]. In particular, PET has excellent tensile and impact strength, chemical resistance, clarity, processability, colourability, and reasonable thermal stability [13,14]. Due to these properties, PET has been used in numerous applications including electronic instruments, automobile products, housewares, lighting products, power tools, material handling equipment, and sporting goods [15].…”
