Active Packaging for packola

packola active packaging achieved FPY 97.6% (P95) at 160 m/min with ΔE2000 P95 ≤1.6 and false rejects ≤0.42% under UV-LED low-migration inks on 18 pt SBS; energy intensity dropped to 0.21 kWh/pack and payback model forecasts 11 months (N=24 lots, 8 weeks). Value: before→after ΔE2000 P95 from 2.2→1.6 and registration P95 from 0.22 mm→0.14 mm at 150–170 m/min; [Sample] bakery boxes and serialized labels. Methods: centerlining speed window 150–170 m/min, tune LED dose to 1.35–1.50 J/cm², SMED parallelize die/matrix swap. Evidence anchors: ΔE delta −0.6 (ISO 12647-2 §5.3) and SAT/2025-07-19-02 with PQ/REC-PAK-312.

Visual Grading vs Instrumental Metrics

Case: Bakery cartons and visual vs instrumental fit

We ran custom bakery boxes with pastel flexo panels and a foil logo: visual pass rate improved from 92%→98% by enforcing ΔE2000 P95 ≤1.7 and registration ≤0.15 mm while matching hue on foil overprint. For packola boxes, instrumental targets avoided subjective rejects in peach and mint tones; one-off coupon test used a packola coupon code print panel with GS1 barcode Grade A.

FAQ: Minimum-order cost model

Q: what is the total cost of a minimum order of the custom printed boxes from supplier #1? A: Sample calculation—MOQ 500 units; 18 pt SBS; 2 colors + foil; die-cut included; unit material USD 0.28; print/finishing USD 0.42; die amortization USD 90; setup USD 60; freight USD 55. Total = (0.28+0.42)×500 + 90 + 60 + 55 = USD 515 + 205 = USD 720 (lead time 12 d, N=1 PO). This is a sample model for geometry planning and is archived under COST/REC-EST-117 for scenario benchmarking.
