What is Hologram Aggregation?
Hologram aggregation is the process of digitally linking individual serialised hologram labels (applied to single product units) to higher‑level packaging – such as cases, cartons, or pallets – by creating a hierarchical relationship in a track‑and‑trace database. Each product unit has a unique serial number (the “child”). A case containing multiple units receives its own unique serial number (the “parent”). The system records which child units are inside which parent case. This aggregation can extend further to pallet level (parent of cases) and even shipment level. Aggregation enables efficient supply chain scanning: instead of scanning every single product unit, a warehouse worker scans only the case or pallet label to confirm the authenticity and movement of all units inside. Aggregation is mandatory for pharmaceutical serialisation in many markets (e.g., EU FMD, US DSCSA) and is increasingly adopted for electronics, automotive parts, and luxury goods. Holoseal provides serialised hologram labels with GS1‑compliant barcodes that are ready for aggregation integration.
🔬 How Hologram Aggregation Works (Step‑by‑Step)
- Serialisation at unit level – Each product receives a unique serialised hologram label (e.g., a Data Matrix code encoding GTIN, batch, expiry, and serial number). These are the “child” units.
- Case aggregation – As units are packed into a case, a machine scans each unit’s code and then prints/applies a new serialised label to the case. The database records that Case “C123” contains units “U001, U002, … U100”. The case label becomes the “parent”.
- Pallet aggregation – Cases are stacked on a pallet. A handheld or fixed scanner reads each case label, and a new pallet label is generated. The database records that Pallet “P456” contains Cases “C123, C124, …”.
- Shipment aggregation (optional) – Multiple pallets are combined into a shipment; the shipment ID is linked to all pallets.
- Verification scans – A warehouse worker scans the pallet or case label. The system retrieves the entire hierarchy and can verify that all child units are accounted for, without scanning each individual product.
📦 Levels of Aggregation
- Unit level (child) – Individual product with its own serialised hologram label.
- Case / Carton level (parent) – A box containing multiple units. Has its own serial number, linked to the units inside.
- Pallet level (grandparent) – A pallet containing multiple cases. Linked to all cases on the pallet.
- Shipment level – A truck or container containing multiple pallets.
🔐 Benefits of Hologram Aggregation for Brand Protection
- Efficiency – Scan one case label instead of 100 individual products – saves time and reduces labour costs.
- Compliance – Required for pharmaceutical serialisation in the EU (FMD), US (DSCSA), and other markets.
- Anti‑diversion – Aggregated scans reveal if a case is missing units (potential theft) or if a pallet appears in an unauthorised location.
- Recall management – Quickly identify which cases and pallets contain a specific batch or serial number range.
- Improved inventory accuracy – Aggregated scanning reduces manual entry errors.
⚙️ Aggregation vs. Simple Serialisation – Key Differences
- Simple serialisation – Each unit has a unique code. Scanning requires individual handling of each unit.
- Aggregation – Unit codes are linked to case and pallet codes. Scanning higher‑level packaging provides visibility into all child units.
🔗 Aggregation and the Hologram Label
The hologram label plays two roles in aggregation:
- On the product unit – The serialised hologram label provides overt security (tilt test) and a unique digital ID for aggregation at the unit level.
- On the case / pallet – The case label may also be a hologram label (or a simpler barcode) to deter counterfeiting of the outer packaging. Aggregation links these labels together.
🌍 Holoseal’s Role in Hologram Aggregation
Holoseal provides the foundation for aggregation: serialised hologram labels with GS1‑compliant barcodes (Data Matrix, GS1‑128, QR codes). We also:
- Supply label data files (CSV, JSON) with all serial numbers and their hierarchical relationships as defined by your packaging structure.
- Advise on barcode placement to ensure reliable scanning during automated aggregation lines.
- Integrate with track‑and‑trace platforms that support aggregation (e.g., SAP ATTP, TraceLink, Antares).
We serve clients across Mumbai, Delhi, Bengaluru, Chennai, Hyderabad, Pune, Ahmedabad, Kolkata, Surat, Kochi, Jaipur, Lucknow, Nagpur, Indore, Vadodara, Ludhiana, Patna, Guwahati, Chandigarh and worldwide.
❓ Frequently Asked Questions About Hologram Aggregation
- Is aggregation mandatory for pharmaceuticals? – Yes, in many jurisdictions. EU FMD requires unit‑level serialisation and that the supply chain (wholesalers) verify the aggregation hierarchy when repackaging. US DSCSA requires aggregation at the case level for certain transactions.
- Do I need special hardware for aggregation? – You need barcode scanners (imagers) capable of reading 2D codes (Data Matrix, QR) and software to manage the parent‑child relationships. Most modern warehouse systems support this.
- Can aggregation be done with paper records? – No – aggregation requires a digital database. Paper records cannot manage the complex hierarchies efficiently.
- What happens if a unit is removed from a case? – The system must be updated to reflect that the child unit is no longer inside that parent. This is typically done during repackaging or returns processing.
- Does Holoseal provide aggregation software? – No – we specialise in the serialised hologram labels and data files. We can recommend third‑party track‑and‑trace platforms that include aggregation modules.
- How to order serialised hologram labels for aggregation from Holoseal? – Provide your packaging hierarchy (number of units per case, cases per pallet), label sizes for each level, and your chosen barcode format. We will produce the labels and supply the data files for your aggregation system. Contact us for a quote.
