Frequently asked Questions
01
What makes Interpac different from traditional corrugators?

Interpac uses cold corrugation — a compact, energy-efficient process that eliminates steam, reduces waste, and brings board production in-house for the first time.

02
How much space do I need to install an Interpac system?

The full line is under 30 metres long and bolts directly to the floor, with no need for foundations, boilers, or extensive building works.

03
What kind of board can I produce with Interpac?

You can produce high-quality, flat, low-moisture board — including B and E flute profiles — ideal for premium printing, digital workflows, and fast processing.

04
How soon can I expect a return on investment?

Most converters see ROI in under two years based on a standard two-shift operation — thanks to lower capex, reduced transport costs, and improved margins.

05
Is technical support available after installation?

Yes — we offer full training, onboarding, and ongoing technical support to keep your operation running smoothly from day one.
