First, the packaging edge: there are no creases on the left and right sides of the true salt, and the fake salt has two obvious creases. The true salt is filled by the filling, and the fake salt is only opened by a bundle of wrapped bags, which are manually filled. The bag that becomes a roll must form a crease.
Second, the packaging seal: the seal of the upper and lower sides of the true salt package is completely aligned, the width and the width are consistent, and the upper and lower seals of the fake salt may be narrow and narrow. The sealing of the true salt is run by the machine, which guarantees the standardization. The fake salt is sealed by hand, and the seal will appear uneven.
Third, the anti-counterfeit label: the label of the true salt is clearly defined, are located in the lower left corner of the word "ä¸ç›". There are no layers of fake salt labels, and the positions of the stickers are uneven. The label of the true salt is a uniform position, while the fake salt is manually pasted and its position may vary.
Fourth, the watermark on the packaging bag: In July 2009, the salt in the production of the packaging bags are printed with a watermark, through the light will see a lot of "middle salt" word. The fake salt is not packaged.
