Can diapers still be used when they are expired?

Now that life is better, many families have bid farewell to traditional diapers and started wearing disposable diapers. I often go to the supermarket and see mothers buying large quantities of diapers to take home. Sometimes, when the supermarket has discounts or promotions, everyone buys them like crazy. But no one pays attention to the production date on it, and it expires after a while after they buy it home. So can expired diapers be used? Moms must watch this.

Diapers expired, bacteria army attacked!

Once diapers are out of their shelf life (unopened), they are prone to breeding bacteria. Why is this?

Special types of paper products, such as diapers, sanitary napkins or toilet paper, need to be sterilized at high temperatures. Paper products that have been sterilized at high temperatures are directly sealed and packaged to prevent bacterial growth. However, the effectiveness of one-time disinfection and sterilization has a time limit. Once the shelf life is exceeded, sterility can no longer be guaranteed.

Therefore, once the expiration date has passed, even if you do not open the package, the diapers inside will begin to breed bacteria.

How long is the shelf life of water-absorbent beads?

Water-absorbing beads are super absorbent resins. According to Baidu Encyclopedia, "polyacrylic acid-based super absorbent resins... have a series of advantages such as low production cost, simple process, high production efficiency, strong water absorption capacity, and long product shelf life." (I have been looking for the specific shelf life for a long time but have not found relevant information, please forgive me~)

According to the detailed description in Baidu Encyclopedia, super absorbent resin has strong physical stability, will not decompose even under strong heat of 300°, and can be stored for a long time without spoiling. From this perspective, although the diapers have passed their expiration date, the water absorption performance of the absorbent beads has not changed much, and they will still absorb water when they are needed (so it is still very useful to use expired diapers as mops or absorbent towels~).

The bottom layer is aging, be careful of leakage/seepage

Whether expired diapers will leak urine, I think this is beyond doubt.

If the diapers you buy at home are expired, then the chances of urine leakage are very high! We have mentioned earlier that the bottom layer of diapers is made of PE film or PE film + non-woven fabric. PE film is easily photo-oxidized, and the bottom layer of diapers that have been stored for three years has aged or cracked.

Expired diapers cannot be used any more, mothers must remember this. Expired items can easily breed bacteria. For your baby's health, please use diapers safely for your child. When buying diapers, you can choose some with the most recent production date and then check the shelf life. I wish the baby grows up healthily.
