“We were juggling 60+ SKUs and running out of calendar before we ran out of orders,” says Laura Chen, Operations Director at North Ridge Snacks in the Upper Midwest. “We needed a way to flex up for seasonal peaks without adding another shift.”
After a three-month vendor review, the team partnered with pakfactory to pilot digital runs on FSC paperboard for their folding cartons and trial a food-safe ink set. The goal wasn’t flashy packaging. It was stable color, faster changeovers, and less scrap—practical wins that show up on the weekly production report.
Company Overview and History
North Ridge Snacks is a mid-sized Food & Beverage brand distributing granola clusters, trail mixes, and protein bites across North America. Typical volumes hover around 250–400k cartons per month, with demand spiking ahead of back-to-school and the holidays. Their packaging mix includes Folding Carton for club packs and Pouches for limited flavors. As the SKU count grew from roughly 35 to 70 in two years, so did the complexity of color control and scheduling.
The team’s buying strategy had been to source a broad set of food product packaging supplies—SBS and CCNB board, clear windows, and low-migration adhesives—through a mix of local and regional suppliers. That kept them flexible, but introduced variation: different mills, coatings, and calipers meant different press behaviors. The result: extra setup passes and on-press tweaks that ate into run time.
Quality and Consistency Issues
On the quality side, the pain was clear. Seasonal SKUs printed across multiple plants showed brand colors drifting by ΔE 3–5 from the master reference. Not every consumer notices a half-step shift in the berry red, but retail partners did—and so did the brand team. First Pass Yield (FPY%) was stuck around the mid-80s on short runs, and rejects ran in the 6–8% range for complex cartons with windows and heavy coverage.
Changeovers were the other drag. A typical day included 8–12 short runs with art swaps, board switches (CCNB to SBS), and finishing changes like Spot UV on club packs. Changeover Time averaged 40–50 minutes per job, with waste running 8–12% on the tighter color work. Flexographic Printing and Offset Printing both had their place for long, steady runs; they were less forgiving when you’re bouncing between substrates and seasonal art back-to-back.
Implementation Strategy
The team ran a structured trial: three SKUs moved to Digital Printing with a Food-Safe Ink set (water-based/low-migration) on FSC-certified paperboard. Targets were ΔE ≤ 2 to the brand palette, FPY% above 92, and a measurable cut in setup sheets. The folding cartons carried a matte varnish for scuff resistance, with Spot UV reserved for two club variants. Window patching and die-cutting stayed in the existing post-press flow to keep the footprint stable.
Vendor due diligence mattered. “We read a lot of pakfactory reviews to triangulate how they handled quick-turn seasonals,” Laura notes. “We also asked about pakfactory location options—where boards were stocked and what lead times looked like in North America so we weren’t shipping air.” Based on a 6-week pilot, they moved 20–25% of SKUs to digital for on-demand runs under 5k units, keeping Offset Printing for base flavors with steady, high-volume demand.
Q: From a production perspective, what is product packaging beyond the box itself?
A: “For us, what is product packaging is really a workflow question. It’s material behavior on press, color control across plants, and how quickly operators can switch jobs without a stack of make-ready sheets,” Laura says. “The digital cell gave us predictable color and shorter changeovers. We still use flexo and offset where it makes sense—this isn’t a one-size call.”
Looking ahead, the team already sees an adjacent use case: accessory kits for devices in their corporate gifting line, which will require different inserts and impact resistance. “It’s basically tech product packaging in small batches,” Laura adds. “Digital and modular die-cutting should give us the control we need without bloating inventory.”
Quantitative Results and Metrics
Six months post-implementation, the numbers settled into predictable bands. Color accuracy improved to ΔE 1.2–1.8 on the digital SKUs against the brand standard. FPY% on those runs climbed into the 93–96% window. Waste Rate on short digital runs moved from 8–11% down to roughly 5–6%, largely due to fewer setup sheets and more stable color on coated SBS.
Throughput on the short-run cell rose by 18–22% once operators got comfortable with the new routine and file prep. Changeovers that used to consume 40–50 minutes now land closer to 25–30 minutes for like-for-like board. The gains weren’t linear—months two and three were choppy as profiles and finishing recipes were dialed in—but by month four, the numbers flattened into a reliable rhythm.
On cost and sustainability metrics, energy per pack (kWh/pack) dipped by roughly 5–7% on the digital SKUs because of fewer reruns and tighter first-pass control. CO₂/pack followed a similar pattern based on internal calculations. The Payback Period for hardware and onboarding landed in the 12–16 month range, given that only 20–25% of SKUs moved to the new cell. Long, steady movers remain on Offset Printing for economics; limited editions and seasonal art sit on digital, where agility matters most.
“We didn’t try to move the world on day one,” Laura concludes. “We stabilized color, kept seasonal launches on schedule, and freed up press time. Based on insights from pakfactory’s project team, the next step is expanding variable data and tighter ΔE control on textured stocks. It’s incremental work, but it sticks.”
