Hot-melt adhesives: what holds it all together

A protection is assembled without stitching. Hot-melt adhesives, laid hot in very fine threads, bond the layers and hold the elastics.

Hot-melt adhesives: what holds it all together

Three families of adhesive

Construction adhesive bonds the layers together; elastic adhesive fixes the threads under tension; positioning adhesive, on some pads, holds the product in the underwear. Each has its formula, its temperature and its application pattern.

Little, but well placed

The quantity of adhesive is counted in grams per square metre and laid in threads or spirals. Too much adhesive stiffens the product and can make it noisy; too little, and a layer comes apart in use. We set the pattern and the dose for each joint.

Our adhesives have no perceptible odour and are compatible with indirect skin contact; they never touch the skin directly.

Our choice

Hot-melt adhesives from qualified suppliers, skin-compatible and hypoallergenic, dedicated formulas for construction and elastics, dose and pattern set joint by joint.

Key points
  • No stitching: everything is bonded hot, in fine threads.
  • The right adhesive is the one you do not notice.
  • Dose set, not maximised.
