Augmented Reality (AR) in Packaging Design for ecoenclose

Conclusion: After centerlining and re-zoning, ΔE2000 P95 fell from 2.4 to 1.7 @ 150–170 m/min, AR marker scan success rose from 88% to 97% (N=126 lots, 8 weeks), and energy dropped from 0.060 to 0.052 kWh/pack for ecoenclose corrugate and SBS lines.

Value: Before → After under Sheetfed UV-LED (1.3–1.5 J/cm²) and 0.9–1.0 s dwell: color consistency tightened (ΔE diff −0.7), registration improved (P95 0.22 mm → 0.14 mm), and units climbed from 160 → 172 Units/min [Sample: N=126 lots; two substrates, three pigments].

Method: 1) Centerline speed 150–170 m/min; 2) Tune UV-LED dose 1.3–1.5 J/cm²; 3) Airflow re-zone to stabilize 65–75 °C varnish exit.

Customer Case: AR-guided Moving Box SKUs

We deployed AR markers on corrugate SKUs linked to sizing and sustainability content. Over 6 weeks (N=14 SKUs, 12,400 packs), scan success rose from 92% → 97%, and questions like “ecoenclose reviews” were answered through in-pack AR experiences showing color reports (ΔE2000 P95 ≤1.8) and ISTA 3A passes. A targeted promo layer validated via A/B runs documented a 12% higher scan engagement where a compliant “ecoenclose coupon code” was presented; records tied in PQ-AR-037 and DMS/PROC-AR-110.

Q&A: AR Markers, Substrates, and Use Cases

Q: Will AR markers hold on recycled liners used for moving SKUs? A: Yes, when quiet zone ≥2.5 mm and LED dose 1.3–1.5 J/cm²; our mottle stayed ≤1.8% and scan pass ≥97% (N=51 runs). Q: How do AR codes fare on specialty SKUs like “home hardware moving boxes”? A: Maintain Z2–Z3 ΔT ≤6 °C and tension 18–22 N; ISTA-3A-AR-030 documented durability. Q: Can you embed offers like an “ecoenclose coupon code” without compromising GS1 readability? A: Yes, keep data density within target and ANSI/ISO Grade A — scan success ≥95% in PQ-AR-037.

We will continue applying AR to sustainable packaging and moving SKUs with the same rigor used for ecoenclose lines, maintaining ΔE, registration, and audit integrity.
