Construction & backsheet
Join the outer nonwoven to the barrier film and assemble the chassis. Controlled bonding keeps layers aligned while preserving the intended softness.
HYGIENE / HOTMELT ADHESIVES
Hotmelt bonding for diaper construction, elastic attachment, absorbent cores, feminine-care positioning and wet-wipe lid attachment.

Review: layer alignment, bond integrity and softness.01 / DIAPER CONSTRUCTION
A diaper combines nonwovens, barrier film, absorbent materials and elastics. Each interface has a different job; adhesive selection starts with that job.
Join the outer nonwoven to the barrier film and assemble the chassis. Controlled bonding keeps layers aligned while preserving the intended softness.
Stabilise the absorbent core and its wrap. The bonding approach depends on the fluff/SAP ratio, core architecture and integrity required after wetting.
Anchor stretched elastic strands or films at the waist, legs and barrier cuffs. Evaluate creep resistance and holding power as the elastics repeatedly extend and recover.
Hold the acquisition/distribution layer and adjacent layers in position. The application pattern must support liquid movement through the designed absorbent structure.
Assess frontal-tape anchoring, side-panel assembly, cuff connections and end seals against the materials and forces at each interface.
Some designs also use hotmelt wetness indicators. These are a separate functional chemistry; suitability and availability need to be established for the specific project.
02 / FEMININE CARE
Positioning adhesive belongs on the garment-facing backsheet and wings. It holds the pad on underwear and is protected by a removable release liner before use.
Balance initial tack and in-use holding power with clean removal from different fabrics. Check for adhesive transfer, fabric damage and liner-release behaviour.
Construction and core adhesives perform separate internal tasks: keeping the absorbent layers assembled and the core stable.

03 / WET-WIPE PACKAGING
Hotmelt attaches the rigid plastic flip-top frame to the flexible film pack. The bonded frame stays fixed while the hinged lid opens and closes.
Evaluate the actual lid resin, film laminate, print or surface treatment and contact area. Adhesion must suit both surfaces.
Apply a consistent adhesive pattern beneath the frame, then position and press it onto the pack. Keep adhesive away from the dispensing opening.
Assess frame peel, repeated opening and closing, pack flexing and compatibility with the wipe lotion. Resealable labels are a different adhesive application.
