This polyolefin hot melt adhesive is specifically designed for bonding wine bottle caps.
Its task is clear: on the high-speed production line, it must quickly and firmly bond the metal body (usually aluminum) inside the bottle cap with the plastic sealing gasket (commonly PE or PVC) to ensure a seal. Whether it’s the aluminum-plastic screw-off cap for wine or the metal cap for spirits, it can handle them all.
Offers powerful adhesion, securely bonding challenging combinations like plastic to aluminum. On high-speed lines, it grabs the liner instantly (excellent immediate tack) and ensures the liner stays firmly in place through shipping, storage, and countless consumer openings (superior long-term cohesive strength).
With its fast-curing, non-stringing properties, it perfectly keeps pace with lines producing hundreds or thousands of caps per minute. This reduces downtime, prevents messy adhesive threads from contaminating equipment or caps, and significantly boosts overall output.
Wines and spirits can face extreme temperature swings, from cold cellars to hot transport trucks. Our adhesive maintains consistent performance across a range of temperatures. Its reliable working range and softening point ensure the seal remains flexible at low temperatures (resisting cracks) and doesn’t over-soften at higher temperatures, guaranteeing integrity throughout the supply chain.
Our optimized formulation aims to “deliver high bonding performance with relatively low adhesive consumption”, helping you control per-unit costs effectively. The product is also eco-friendly, featuring a solvent-free, low-odor formula that’s safer for both your production environment and the planet.

A1: This is a classic “seasonal” issue with hot melt adhesives. A significant drop in ambient temperature causes the adhesive to cool too rapidly. This shortens its open time and reduces flexibility. The solution: before winter sets in, get in touch with us. We can suggest fine-tuning your application temperature (slightly increasing it within the recommended range) or switching to a “winter-grade” formulation specifically optimized for low-temperature performance to ensure stable results.
A2: First, immediately check if your operating temperature is stable at the lower end (or below) of the recommended range (160-180°C). Temperature being too low is the primary cause of stringing. Next, inspect the dispensing nozzle for wear or any residue of partially cured adhesive. If the problem persists, we can provide a specialized variant with enhanced anti-stringing performance.
