What is hot melt adhesive for case and carton sealing?
SIS hot melt adhesive
EVA hot melt adhesive
polyolefin hot melt adhesive

Using hot melt glue as the bonding and sealing material for sealing cardboard boxes is a packaging method. It ensures a strong bond, preventing the boxes from splitting during transportation and storage. The quick setting time enhances packaging efficiency, making it suitable for large-scale automated packaging production lines. The main type are eva hot melt adhesive, polyolefin glue, and SIS glue.

Where is it used?

UNISN Carton Sealing Hot Melt Adhesives are primarily used in: The hot melt adhesive machine heats the solid cardboard adhesive to a molten state, then applies the liquid adhesive evenly to the carton's sealing flaps using a glue gun or nozzle. After closing the flaps, the adhesive cools and solidifies, creating a strong and secure seal.

Who uses it?

• Food and beverages manufacturer       • Packaging manufacturer       • And more.

How to use?

•Hot Melt Adhesive Machine (includes melting tank, power and control circuits, pump body, and manifold)
•Melting, storing, and transferring hot melt adhesives; temperature control.
•Hose (includes thermostat, heater, spray gun, power cord, etc.)
•Insulated delivery and pressure transmission.
•Spray Gun (includes heating elements, nozzle, flow and temperature adjustment devices)
•Controls adhesive volume, spraying or extrusion, triggering, and operation.
1.The melting tank of the hot melt adhesive machine heats solid hot melt adhesive into a fluid liquid.
2.The molten adhesive is transported to the spray gun through a pipeline by a pump inside the machine.
3.The spray gun sprays the molten adhesive evenly onto the bonding positions of the carton in the form of mist, lines, or dots.
4.The hot melt adhesive cools and solidifies quickly, forming a strong bond in a short time

Usage and Precautions

Maintenance Recommendations

Weekly: Check connections. Inspect the compressed air filter bowl. Drain adhesive residue. Quarterly: Drain adhesive to remove carbon deposits from the manifold.

Biannually: Inspect/replace the filter screen.

As Needed: Replace the spray gun body, nozzle, and filter screen, and clean the adhesive machine.

Precautions

1.Do not exceed 180°C when heating.
2.Avoid mixing different types of hot melt adhesives.
3.Wear gloves and safety goggles or a face shield when adding adhesive or performing maintenance.
4.Add materials carefully to prevent splashing and burns.
5.Maintain proper adhesive levels to avoid splashing during refilling.
6.Keep a bucket of cold water nearby for immediate treatment in case of burns.
7.Position the adhesive machine and related equipment below eye level.
