How to Choose a Flexo Press for Flexible Packaging

Aug 14, 2026

Default to CI for multi-color stretchy film; pick colors (usually 6, 8 if white/varnish weekly), then drive by CapEx and changeovers, then usable speed matched to drying—not brochure max. Quote by width, materials (PE/BOPP/PET), and SKU mix; never drop CI for cheap stack on PE film.

Decision order	Flexible packaging default
1. Architecture	CI for multi-color stretchy film — vs stack
2. Colors	Usually 6; 8 if white/varnish weekly — 6 vs 8
3. Drive	Geared / servo / gearless by CapEx & changeovers — drive guide
4. Usable speed + drying	Usable ≠ brochure max — speed bands

Why Flexible Packaging Usually Means CI Flexo

Flexible packaging webs — especially PE and thin BOPP — stretch under tension and heat. Central impression keeps the web on one drum while colors print, which is why CI is the default architecture for multi-color film converting. Stack can still appear on paper or simpler jobs; gravure may win ultra-long stable SKUs — CI vs gravure.

Budget Bands for Flexible Packaging Presses

Band	Spec shape
Low	Gear-driven CI · 4–6 colors · honest usable speed · do not drop CI for cheap stack on PE film
Medium	6-color CI · servo (or gearless if SKUs churn) · dryers matched to usable m/min
High	8-color gearless CI · auto-register · drying/register packages sized for thin film waste control

Materials — PE / BOPP / PET / Laminates

PE bags / film — CI + tension discipline. PE guide
BOPP snack / retail — CI + heat/drying. BOPP guide
PET / laminates — CI common; RFQ must state gauge and ink system
Paper cups / non-woven — different web physics; see application hub cups / film / non-woven

Colors for Packaging Artwork

Count separations on the worst recurring SKU. Process + limited spots → 6-color CI is the mainstream flexible-packaging workhorse. White, varnish or brand spots weekly → 8. Idle stations still cost CapEx and dryer load.

Flexible Packaging Scenarios

A — PE shopping / garbage bags, CapEx first: Gear-driven 6-color CI. 6-color CI →

B — Film · 1000–1300 mm · ~350 usable: King-class CI (≤350). Match drying before chasing brochure max.

C — Premium pouches, white/varnish, mixed SKUs: 8-color full servo gearless CI. 8-color gearless →

D — Ultra-long stable SKUs only: Re-check gravure economics before over-specifying gearless CI.

FAQ

Is CI flexo suitable for flexible packaging?

Yes — it is a primary process for PE, BOPP, PET and CPP film packaging when multi-color register and usable speed matter.
