A look at the packaging: refined iodized salt is packed in polyethylene plastic, printed with the words iodized, and marked with the production unit and factory date. The handwriting is clear, the packaging bag is of good quality, beautifully printed and tightly sealed; Counterfeit iodized salt has blurred handwriting and rough packaging.
Second, look at the sealing: the real salt is mechanized, and the edges of the upper and lower sealing lines are wavy, while the edges of the fake salt sealing line are serrated; True salt has no creases, and fake salt has creases on both sides.
Third, look at the anti-counterfeiting logo: there are anti-counterfeiting trademarks and anti-counterfeiting codes on the real salt package, and there are anti-counterfeiting QR codes on the back of the package. You can check the authenticity by scanning.
It is quite reliable to check the authenticity through these three points. After inspection, it was found that the salt bought was real. I have been buying this brand of salt until now, and I have never met a fake. After all, "Yiyantang" is the brand of listed companies, and the salt of big brands is still relatively reliable. "
