Elastic is tricky to stick.
Think about it. The elastic is stretched 2.5 to 3.5 times. The glue must hold it in that stretched state. And it must stay that way for months. That is the job of our Elastic band adhesive for sanitary napkins. It keeps the barrier cuffs and leak-proof sides working. On the fast production line, the glue applies cleanly. It sets instantly. No stringing. No clogging. In our factory tests, the glue stays elastic for months. It does not get hard. It does not break. That comes from 28 years of experience.
What makes SIS so good for this?
SIS is known as the best material for fixing elastic. It has high elasticity. It has good initial stickiness. Our formula mixes SIS with special tackifying resins. That gives both flexibility and strong bonding. The glue works on lines of 400-800 pads per minute. At 150°C, the melt viscosity is 2500-4500 mPa·s. That is a perfect range for slot or spiral spray. It forms a fine, even glue web. That web wraps around every single elastic thread. That is the power of our Elastic band adhesive for sanitary napkins.
Anti-creep is the most important number.
We optimized the SIS molecular weight and plasticizer system. The glue has a creep recovery rate of over 95%.

When peeled, the glue breaks itself. It does not peel off the elastic. No glue transfer. No thread slip. Very low odor. Skin-friendly. No harmful phthalates. That is our Elastic band adhesive for sanitary napkins.
