From Dec.12 to 14, our delegates were invitated to attend the last conference of making Chinese Window Films Standard which held by China Building Material Test&Certification Group. As we know, there is no official standard for window film industry in China now, and it caused big trouble to marketing. Many small and illegal wholesellers or distributors just use low end products to cheat customers. During the conference, nearly all Chinese influencial manufactuers and distributors as well as delegates from 3M, Llumar joined the discussion. Our delegates provided many useful points to the editorial committee and through the discussion, we established good relationship to other manufactuers and potential customers.
