Hot melt adhesive is a type of malleable adhesive. Within a certain temperature range, its physical state changes with temperature, while its chemical properties remain unchanged. Here is a detailed analysis of hot melt adhesive in diapers:
Environmental friendliness of hot melt adhesive: Hot melt adhesive is non-toxic and odorless, belonging to environmentally friendly chemical products.
It is solvent-free, pollution-free, has a simple production process, and offers high bonding strength and fast processing.
Uses of hot melt adhesive in diapers: The production process of diapers is a complex assembly process, combining various materials (such as the surface non-woven fabric, absorbent core, PE composite bottom film, etc.).
These materials are bonded together using hot melt adhesive, an indispensable part of the diaper production process.
Regarding adhesive dripping on diapers: During the diaper production process, sometimes adhesive dripping occurs, which appears as a yellow, glue-like substance.
Dripping occurs because pores are blocked during production, causing the adhesive to solidify into clumps and drip onto the product. With current technology, the formation of epoxy resin cannot be completely avoided.
The Effects of Hot Melt Glue on Babies:
Although the glue residue is a manufacturing defect, it does not cause any harm to the human body.
Hot melt adhesive itself is non-toxic and odorless, therefore, the glue residue will not harm babies.
The Odor of Hot Melt Glue:
The odor of hot melt adhesive comes from its raw materials and manufacturing process.
These odors are non-toxic, and the smell dissipates quickly after the packaging is opened and left for a while.
Newly manufactured diapers may have a "kerosene smell," which is the smell of hot melt adhesive and antibiotics, and is harmless to babies.
