While the structural adhesive used in disposable diapers does not come into direct contact with the user, its performance and the manufacturing processes involved indirectly impact the product's safety and comfort. Although parents do not need to handle the "glue" directly, understanding the underlying principles of its usage can aid in making informed purchasing decisions and ensuring the proper use of diapers.
Prioritize Brand-Name Products with Safety Certification.
The structural adhesives used in reputable brands of disposable diapers comply with GB 33372-2020 (*Limits of Harmful Substances in Adhesives*) and GB 15979-2024 (*Hygienic Requirements for Disposable Sanitary Products*), thereby ensuring that no harmful residues-such as formaldehyde, benzene, or heavy metals-remain. It is recommended to check the product packaging to verify that the applicable standards are clearly indicated, in order to avoid purchasing uncertified or unregulated products.
Check the Diapers for Any Unusual Odors
Although the structural adhesive used in manufacturing cures upon heating, reputable products should be free of any noticeable odors. However, if you detect a pungent chemical smell, it may be due to adhesive residue or the use of low-quality raw materials. It is recommended to inspect the diapers before their first use; if you notice any unpleasant odors, discontinue use immediately.
Observe Your Baby for Any Skin Redness or Allergic Reactions
Although the structural adhesive is encapsulated within multiple layers of material and does not come into direct contact with the skin, poor diaper design or-in very rare instances-adhesive migration could indirectly trigger skin irritation. If your baby frequently develops a "red bottom" (diaper rash) and this issue appears to be linked to a change in diaper brands, consider whether it may be a reaction to the overall materials used in the product (including the bonding agents and manufacturing processes).
