Hot Melt Construction Glue for Diaper and Sanitary Napkin Manufacturing

This hot melt construction glue is a light yellow solid adhesive supplied by WEIHONGLAI for disposable hygiene-product production. It is formulated for construction bonding in baby diapers, sanitary napkins, and adult diapers, where a reliable bond between substrates must hold through converting, folding, and end use.

Application Scope

Construction glue can be used for baby diaper, sanitary napkin, and adult diaper production. It is intended for construction bonding positions on the converting line, where the adhesive is applied and the substrates are brought together under the line's own pressure and speed settings.

Because runnability depends on your substrate combination, coat weight, nozzle setup, and line speed, we recommend confirming the grade against your actual process before a full production run. Related materials in the same program include hot melt construction glue for diaper and sanitary pad manufacturing, and you can review the wider range through the non woven fabrics category page.

Sampling and Trial Guidance

• Request a sample of the construction glue grade before committing to a production quantity.
• Run the sample at your normal operating temperature within the 90–105 ℃ range and at your standard coat weight.
• Check bond performance after folding, compression, and any downstream converting steps on your line.
• Confirm carton size (18 kgs or 20 kgs) and palletized loading against your warehouse and container plan.
• Store remaining material below 40 ℃ in a cool, dry place and use within the 12-month shelf life.
