InvisiPac HM50

The Graco InvisiPac HM50 is a high-performance Tank-Free™ hot melt dispensing system capable of producing up to 22 kg of hot melt adhesive per hour. It is the ideal solution for high-volume end-of-line packaging applications requiring speed, precision and reliability.

Key features High productivity: 22 kg/h melting capacity ensures a continuous flow of adhesive even on demanding packaging lines. Fast start-up: Reaches operating temperature in just 10 minutes — the fastest start-up time on the market. Tank-Free™ technology: The tankless system eliminates adhesive charring and thermal shock, extending equipment lifespan.

FIFO principle: The first adhesive in is melted and dispensed first, ensuring material quality. Flexible number of outputs: Configurable from two to six output channels according to line requirements. Automatic vacuum feeding: Reduces manual handling and ensures an uninterrupted adhesive supply.

Integrated pattern control: Allows presetting of different adhesive patterns for accurate and repeatable processing. Typical applications The InvisiPac HM50 is particularly suited to high-volume packaging lines requiring reliable and automated hot melt dispensing: carton box sealing, bag sealing, tray carton assembly and the bonding of multilayer packaging.

Key features

• Tank-Free™ system supplies hot melt material on demand for packaging bonding
• In-line melter can produce 22 kg per hour and reaches operating temperature in 10 minutes — the fastest start-up time of any packaging line
• Melt-on-Demand technology ensures a continuous flow of adhesive. Less time at high temperature means more uptime and less maintenance-related downtime
• FIFO (first-in, first-out) ensures that the first adhesive is melted and dispensed first, which eliminates adhesive charring and thermal shock
• Integrated automatic vacuum feeding system saves labour costs by automatically drawing adhesive from a drum or bulk container
• Operator safety — no contact with molten hot melt reduces the risk of burns
• Pattern control switches dispensing from a solid bead to a stitched bead at the push of a button, saving time and money
• Optional signal light visually indicates the system status
• Intuitive user interface monitors adhesive consumption and simplifies troubleshooting with usage data, error and event history downloadable via USB
