Hello, the landlord, there are two kinds of packaging for the company's pure milk, one is brick aseptic packaging provided by Tetra Pak Laval Company, and the other is brick aseptic packaging provided by SIG Combibloc Company. Because the two companies provide production equipment and packaging materials, except for the difference in the molding method of packaging materials (Tetra Pak is a coil, so the box is folded up and down after molding; Combibloc itself is a molded packaging material, so there is no corner at the bottom of the box), and there are some differences in product identification and labeling (there is no difference in product quality). Our company's products have no special anti-counterfeiting marks. Please look for the "Yili" trademark and the "halal" logo when buying. Hope to adopt
