Seal Sentry Verifies Hot Melt Seals Online

Nordson Corporation - Packagingntry examines hot melt beads on a carton, including those compressed between flaps, helping deliver a properly sealed package every time. Online sensors check five conditions: beads drifting off target, missing beads, irregularly shaped beads, bead proportions after compression, and bead placement measured through substrate flaps.

Manufacturers set the tolerance level that defines system or package failure. Tight tolerances generate early warning signals useful in preventing unscheduled downtime. Larger deviations keep production levels high yet verify quality of the package seal.

Applications include real-time management of package sealing standards; seal validation of pharmaceutical and medical packaging; quality assurance of food and beverage packaging; and quick testing of new substrates, new adhesives, new vendor's supplies, or new package designs. Also, the system provides immediate feedback on new machinery or modified maintenance procedures affecting box sealing quality.
