“We needed to triple capacity without tripling our footprint,” said Elena Ruiz, Operations Director at Horizon Cups & Plates. “And we had to do it without unsettling our customers.” Her team began by mapping every choke point from stacking to final packout. They also spoke with **shrink wrapping machine manufacturers** across Europe and Asia, looking for modular systems that could drop into their existing line without a long shutdown.
The baseline wasn’t flattering: OEE hovered around 65%, changeovers routinely stretched 45–60 minutes, and scrap in multipack wrapping sat near the 7–9% range during peak months. The real sting came from rewrap labor and re-inspections after cosmetic defects on printed film or miscounts.
The turning point came when the team piloted a servo-synchronized wrapper with a dual-lane infeed and a short accumulation buffer. That small buffer, paired with smarter counting, let them decouple the upstream forming and printing from downstream shrink. It sounds minor. On the floor, it was night and day.
Company Overview and History
Horizon is a 20-year-old, family-owned converter serving quick-service restaurants across EMEA. Annual volumes run in the 120–150 million range for hot and cold cups, plus 40–60 million plates, with seasonal spikes around summer travel and holiday promotions. The plant footprint is tight: three forming cells for cups, two for plates, and a shared finishing area where wrapping and palletizing compete for space. Their product mix includes plain and brand-printed multipacks and retailer-specific promotions.
Historically, Horizon relied on a dedicated paper plate printing machine for mid-volume SKUs and outsourced overflow to a regional trade printer. Plates were formed on legacy assets and handed off to a small cup plate machine cell for specialty skus like tasting trays. Cups came off older forming units and went straight to manual packing when shrink capacity was tied up. None of this was catastrophic, but the handoffs bred inconsistency and small, expensive delays.
Compliance was non-negotiable: EU 1935/2004 for food contact, FSC on paper, and line-side hygiene controls. That guardrail, combined with retailer audits, limited the options for quick fixes. The team ran one digital press for short-run artwork and several flexo stations for higher volumes. Color needed to land within ΔE 2–4 for 95% of jobs to keep retailers off their back. Until the rebuild, holding that window during busy weeks was harder than it should’ve been.
Technology Selection Rationale
On the mechanical side, the debate was monoblock versus modular. Monoblocks were compact, but servicing them in a crowded aisle would be a headache. The team chose a modular shrink wrapper with a servo-driven infeed, photo-eye counting, and a short accumulation table. It docked neatly behind their new automatic paper cup machine and an upgraded disposable paper cup making machine. Typical forming speeds are 110–150 cups/min per lane, while the new wrapper handles 35–50 multipacks/min, depending on film gauge and count. The goal wasn’t chasing headline speed; it was consistency through peaks.
On print, they kept the in-house automatic flexo printing machine for plates and switched to low-odor, water-based inks for most paper jobs, reserving UV-LED for specialty varnishes. Shrink film remained pre-printed by a trusted supplier, but Horizon took tighter control of color targets and inspection. For mid-volume plates and promotional kits, the legacy paper plate printing machine stayed in the mix for quick-turn work. That mix—outsourced film printing, in-house plate work—reduced changeover pressure on any single asset.
There was a fair question from the team: “If we have flexo for plates, do we still need the dedicated paper plate printing machine?” The answer was yes, for two reasons. First, it absorbed oddball SKUs without slowing the main flexo schedule. Second, it kept the door open for micro-runs with tight deadlines. On wrapping, they added an energy-metered tunnel with three-zone control. The first two weeks were choppy—film spec variations caused layflat drift—but once they tightened the spec with the supplier, pack aesthetics stabilized.
Quantitative Results and Metrics
Six months after ramp-up, the numbers settled into a predictable band. Throughput on wrapped SKUs is up around 20–25% depending on the shift, matching the headline 23% they set in their business case. Waste from miscounts and scuffed film fell roughly 25–30%, with ppm defects down by 35–45% on the worst offenders. FPY climbed from the mid-80s to 93–95% on steady weeks. Changeovers, once 45–60 minutes, now land between 18 and 22 minutes for format-only changes, a tangible relief for the afternoon shift.
Energy and sustainability got attention too. kWh per pack dropped by an estimated 10–14% thanks to better tunnel zoning and fewer rewraps. CO₂ per pack trended 8–12% lower using Horizon’s internal LCA model; not lab-grade science, but directionally sound and accepted by their retail customers. Payback penciled in at 14–18 months, depending on film costs and labor assumptions. The in-house automatic flexo printing machine now carries more plate work at steady speeds, while the cup plate machine handles small specialty orders without disturbing the main line.
It wasn’t flawless. Week three, a flaky encoder threw off count accuracy, and a full shift of rework followed. Film gauge variation also forced a tweak to tunnel temperature and conveyor speed profiles. The crew documented recipes—line speed, tunnel zones, count logic—for each SKU family, and the wobbles calmed down. Looking ahead, Horizon plans to mirror the setup on a second line to de-risk peak weeks and to revisit options with **shrink wrapping machine manufacturers** on inline print-to-pack for certain promotions. Not every SKU will warrant it, but the door is open.
