The company is not involved in the competition for copper foil products below the hvlp3 grade, as its process route does not have a cost advantage in producing copper foil below the hvlp3 grade. However, the company's process route has certain advantages in producing ultra-thin and ultra-flat copper foil; therefore, the company has chosen to start market development with HVLP5 grade copper foil products"
