Barcodes once carried a price and a SKU. Now a single QR code can unlock a living specification: materials, recycled content, manufacturing batch, refill status, safety certificates and end-of-life guidance.
Digital product passports (DPPs) turn that information into a persistent, machine-readable record that follows every pack. When built for real operations—not just pilots—passports cut reporting effort, prove claims, improve sortation and make reuse practical.

Why packaging data matters now
Good packaging decisions start with facts you can reuse across compliance, customers and plants.
Prove claims with evidence
Recycled content, mono-material design and food-contact compliance rely on verifiable inputs.
A useful passport stores the bill of materials (polymer family, additives, barrier layers, adhesives, inks), component masses, converting site and production date. With this in place, recycled-content declarations and design-for-recycling checks become audit-ready.
Simplify EPR and labelling
Extended Producer Responsibility rules, taxes and recyclability labels vary by market. When specifications are structured, a rules engine can turn one set of facts into many country reports—reducing manual rework and the risk of inconsistencies.

By GlobalDataImprove sorting, reuse and returns
A scannable code on the label or closure can tell smart bins and depot scanners the resin family, sleeve removal, and whether the adhesive is wash-off.
For returnable cups, crates and totes, a persistent ID tracks deposit status, wash cycles and retirement reasons, tightening loops and cutting losses.
Sharper recalls and fewer write-offs
Batch-level provenance (which converter, which input lots) helps isolate off-odour ink, under-cured adhesive or out-of-spec pigment. Serialised IDs on safety-critical lines make recalls precise and cheaper.
Clearer guidance for consumers
People scan when there’s value. A public view of the passport can present short, localised instructions—“PE bottle: recycle with cap; peel sleeve via tab”—plus recycled-content context and refill locations without cluttering artwork.
How to build passports that work beyond the pilot
Think of a DPP as a small database entry with two doors: a secure B2B door and a public door. Start lean, use open standards and bake data capture into your existing artwork flow.
Choose a minimum viable schema
Begin with a tight field set:
- Identity: GTIN, batch/lot, optional serial (for reusables/high value).
- Composition: primary polymer(s) and %, barrier layers (EVOH/aluminium), adhesive/ink families, closure material.
- Mass & format: component weights, closure type, label/sleeve area.
- Claims & certificates: recycled-content %, food-contact status, standards/approvals.
- End-of-life cues: targeted recyclability guideline, sleeve removal, wash-off adhesive, detectable black, tethered cap.
- Provenance & dates: converting site, date code, mould/cavity (if relevant).
- ESG basics: per-unit footprint (if available), turn count for returnables.
Use identifiers that scale
Adopt GS1 Digital Link for the QR so one code routes to many experiences (ingredients, safety, recycling).
Add serialised QR or RFID/RAIN where bulk reads matter (reusable assets). Keep one canonical ID across label, carton and back-end systems to prevent data forks.
Separate public and restricted views
Publish plain-language guidance and claim summaries publicly; keep exact formulations, supplier lots and certificates behind permissions for customers, auditors and regulators. One passport, two views.
Pick pragmatic formats
Use JSON-LD with a small packaging vocabulary; link to evidence (test reports, certificates) rather than embedding files. Lean on GS1 keys and common material names to avoid translation layers.
Make authoring part of artwork
When designers pick a sleeve film or pigment, prefill fields; when procurement swaps an adhesive, change control triggers re-validation. Block release if mandatory fields are missing. This turns passports from a late spreadsheet into part of the spec.
Design codes for real lines
Place QR on flat, scannable faces; avoid edges and high-gloss glare. On curved bottles, use ladder orientation and generous quiet zones. Test scan rates on retail tills, conveyors and (where possible) MRF pilot lines.
Governance that lasts
Assign field owners (R&D for composition, Packaging for format, Quality for lots). Version-control passports, set retention (e.g., 5–10 years for batch data) and log changes. When suppliers change, the passport updates—under control.
Implementation playbook: from one line to many
Start where a passport solves a real problem, prove value, then scale by template—not heroics.
Pick a narrow pilot with clear payback
Examples: a PET bottle family with wash-off labels; a returnable cup/tote needing cycle tracking; a skincare pump range with recycled-content claims. Limit SKUs and markets to keep feedback fast.
Connect your sources of truth
Map facts to systems: PLM for materials, ERP for suppliers, LCA for footprints, compliance repository for certificates, artwork for print. Decide which system masters each field; link rather than copy where possible.
Publish two experiences from one record
Create a lightweight public page (localised recycling guidance, claim context, provenance). Provide a permissioned B2B/audit view with detailed composition and certificates. Avoid multiple codes by using routing.
Test in the wild
Measure scan rates, mis-reads and glare in stores and warehouses; verify MRF detection where partners allow. Validate data accuracy by sampling finished goods against declared composition.
Wire data to reporting
Use the same fields to auto-fill EPR submissions, recyclability labels and buyer questionnaires. Track time saved at the next cycle to justify scale-up.
Scale with templates
Build templates for common families (PET bottle + sleeve; PP tub + IML; laminated pouch; glass jar + metal lug). Each template carries known fields, validation rules and default guidance. Roll-outs become cloning and tuning.
Track outcomes, not uploads
Monitor scan rate, data completeness, reporting time saved, audit issues avoided, recycled-content variance vs claim, sort reject-rate change at partner MRFs, refill turns, and consumer engagement with recycling guidance. Iterate based on what moves these numbers.
Privacy, security, IP
Protect recipes and supplier IP with access control; sign feeds and use HTTPS. Rate-limit public lookups and agree up-front what becomes public.
Avoid common pitfalls
Over-scope on day one: start with essentials; add LCA depth later.
- Code clutter: one QR with smart routing beats a forest of icons.
- Spec drift: lock passports to artwork versions; require approvals for substitutions.
- Orphaned ownership: assign field owners and escalation; unattended passports decay.
- Dead links: host on stable domains with long-term redirects.
The takeaway for operators
Packaging data and digital product passports can be modest in scope and big in impact. Start with a lean schema, open IDs and built-in authoring.
Prove value on one line, then scale by template.
Done well, DPPs turn labels into living specs that cut reporting effort, back claims with evidence, guide sorting and reuse, and give customers the clear, local instructions they actually need.
