I don't know if you have a cleanliness habit like me when you shop: as long as there is a production date, you will carefully check the production date, shelf life, and carefully calculate the expiration time.

I went shopping in a small supermarket a few days ago, and I found a certain kind of product. There were a few in a pile playing traversal. I thought it was because I remembered the date incorrectly. I took out my phone and checked the date. That’s right. Today is September 6, 2020, but why is the production date on these products September 8, 2020?

In fact, this is not a food traversal, nor is it a time and space disorder, and it is even more unlikely that the manufacturer has printed the numbers wrong. There are only three kinds of truths: ①The bad merchants made tricks on the product's delivery date, instead of marking the production date on the same day, but writing the delivery date a long time later to improve the product sales cycle; ②The products themselves It is about to expire or has expired. The merchant erased the original production date and wrote a new production date. However, the date written this time is too late; ③This batch of products may be counterfeit.

Food safety is a major event that involves the vital interests of thousands of households, and food safety must not be taken lightly. The police remind consumers that they must pay attention to distinguishing the production date of the private modification, so how to distinguish whether the production date has been privately modified?

1. Look at the quality of the food itself, if it is found that the product is deformed or the outer packaging is damaged. It is necessary to find a business for replacement in time.

2. Wipe by hand.

①The original production date, steel stamp or EFI production date on the product packaging cannot generally be wiped off by hand.

②The production date mark on the laser marking machine (ie laser marking machine) cannot be altered or removed. It is permanent and cannot be wiped. It will not be affected by the environment (touch, acid and reduced gas, High temperature, low temperature, etc.) or disappear over a long period of time. The mark made by the laser marking machine: delicate, fine and clear, beautiful, and feel good.

③The production date printed with ink can be easily altered, and the altered production date can be lightened and blurred when wiped with hand.

3. Look at the color of the date. The real production date is clean and neat, and the color is good. The fake production date is usually blurred, with ink marks around the date, and the color is dark.

The above three methods are applicable to most products to identify whether the production date has been altered. However, it is difficult to identify whether the production date of a small part of the product has been altered, such as: the production date of a sticker, replace one With new labels, it is difficult to identify whether the production date has been changed.

Because of the short shelf life of food, tampering with the production date occurs from time to time. Once exposed, it will seriously affect consumers' trust in food brands. In order to avoid this phenomenon, reminding consumers to take precautions is one aspect, and containment from the source (manufacturer) is the fundamental. Laser marking production date is one of the important means.

The markings of the laser coding machine are clean, clear and delicate, beautiful, and feel good. The most important thing is that the laser marking is engraved. It is impossible to erase without damaging the packaging or the product itself, let alone leaving no traces. The modification has a better anti-counterfeiting effect. Therefore, the laser coding machine can effectively prevent the dealer from changing the production date of the product privately.
