We manufacture barcoded seals for all industries to eliminate the possibility of human error. When data is entered manually, there’s always the chance that a recording mistake might occur. Barcode scans are not only reliable, they also take infinitely less time than data entry by hand. Barcoded seals come in various types, such as pull-tight, cable, bolt, strap, and plastic padlock seals.
Barcoded seals are tamper-evident security seals printed with a machine-readable barcode in addition to a sequential serial number. The barcode links the seal to a specific shipment, container, or inventory record in a management system, allowing it to be scanned at any checkpoint in the supply chain. They are available across multiple seal types, including plastic pull-tight seals, fixed-length seals, bolt seals, and cable seals, making them a versatile tracking tool for high-volume operations.
The primary benefit is speed and accuracy. Scanning a barcode takes seconds and eliminates the manual transcription errors that occur when staff hand-record serial numbers at loading and unloading. Barcoded seals integrate directly with inventory management systems, allowing operations to track seal issuance, application, and removal in real time. This creates a complete, auditable chain of custody without additional paperwork or manual data entry.
The barcode closes the audit trail that a tamper-evident seal creates. When a seal's barcode is scanned at origin and again at destination, any discrepancy in the number immediately flags a potential breach before the load is accepted. Combined with the physical tamper evidence of the seal itself, barcoded seals make it significantly harder for a switched or cloned seal to go undetected, because the substituted seal's barcode will not match the scan record from the point of loading.
The barcode format, whether Code 39, Code 128, or others, can typically be specified to match your existing scanning infrastructure. Code 128 is the most common choice for high-density encoding and compatibility with standard warehouse handheld scanners. For operations that need the highest security level, barcoded bolt seals and cable seals combine the physical strength of ISO 17712-rated seals with the tracking capability of machine-readable identification.
Yes. Barcoded seals are available with sequential serial numbers, company name, logo, color coding, and a barcode printed or laser-engraved on the seal body. Sequential numbering is critical because it allows you to spot a gap in the sequence at a glance, which would indicate a seal was removed or lost outside of the normal process. Minimum order quantities apply for fully custom runs; contact us with your specifications for a quote.
Barcoded seals follow standard formats, typically Code 39 or Code 128, that are readable by most commercial handheld scanners and warehouse management systems. Your team scans the seal at loading, records the data against the shipment or asset ID in your system, and scans again at each checkpoint or on delivery. If your system requires a specific format or starting number sequence, that can be specified when ordering. Contact us with your WMS requirements.
Use a scanner with sufficient depth of field to read the barcode without pressing against the seal, particularly on bolt seals and cable seals where the barcode surface may be curved or textured. Scan the seal before application and immediately after removal, and never rely on visual number verification alone when a scanner is available. Maintain a backup manual log of serial numbers for checkpoints where scanning infrastructure may be unavailable.
Pricing depends on seal type, print method, barcode format, and order quantity. Barcoded plastic pull-tight seals are the most affordable option and are practical for high-volume use. Barcoded bolt seals and cable seals are priced higher, reflecting higher-grade materials and the added laser-engraving step. Contact American Casting and Manufacturing at (800) 342-0333 for volume pricing on your specific seal type, and note that sample orders are available before committing to a full run.
