Thermal & logistics
Fiber Box: built for your lanes.
When temperature control is the brief, Fiber Box delivers molded-fiber insulation designed to nest for better cube, ship denser, and qualify in real distribution—including against legacy foam and waxed corrugated where those baselines apply. RENW helps teams map packout logic, QA checkpoints, and rollout order with clear comparisons.
- Thermal performance vs EPS and waxed corrugated in qualified lanes
- Nesting and pallet patterns aimed at freight and warehouse efficiency
- Sampling and qualification paths aligned to how you actually ship
Process overview
From biomass to finished packaging.
RENW is building a repeatable drop-in vertical solution that moves from renewable biomass inputs through package engineering, production readiness, and finished-pack rollout with clearer quality, timing, and cost control.

Biomass inputs
Renewable fiber inputs are selected against the structural, barrier, recovery, and supply requirements of the target packaging program.

When the fit is right
Savings show up across the whole operation.
The win isn’t only the box price. Nesting tighter, shipping fewer empty cubes, and simpler handling on the dock often matter as much as the material itself.
When your specs are clear, we help you turn that into a business case — numbers and assumptions your procurement and ops teams can stand behind.
Two ways to start
Book a technical call to align on your route, loads, and what “good” looks like — or skip straight to samples if your team is already there.
