This is the glue you use every day.
On most of your line. For most of your bonds. Our heat melt glue is the most used structural glue on our diaper line. It handles over 80% of the bonding work. Top sheet to acquisition layer. Back sheet to nonwoven. Core to layers. Barrier cuffs. Leg elastics. It does not aim for super strong. It does not aim for super easy peel. It aims for reliable. Stable. Medium-to-high bond strength. Long-lasting structure.
The formula is classic SIS medium-temp.
SIS base. Hydrogenated C5/C9 resin. Food-grade white oil. The working temperature is 140-160°C. At 150°C, the melt viscosity is 2500-4500 mPa·s. Works on all coating methods. Spiral spray. Fiber spray. Slot coating. The glue lines are fine and even. No stringing. No leaking. No clogging. The softening point is 80-95°C. The glue comes as light yellow clear or semi-clear pellets or blocks. We control every batch strictly.
Here is the balanced data.
180° peel strength is 5-10 N/25mm. Loop tack is 8-12 N/25mm. Holding power lasts over 48 hours at 40°C with a 1kg load.
