The product story

Designed for Performance, Built for the Bin

EarthWise Cellulose is paper-based insulation built for shipments where sustainability isn’t an afterthought, it’s part of the spec. Made from recycled material and certified OCC-E curb-side recyclable, it ships flat, cutting inbound freight and storage footprint, or pre-assembled for a faster pack-out, and goes straight into the recycling bin with the corrugated box once the shipment’s done.

The cellulose fibre construction holds its own thermally, with R-values validated across three insulation thicknesses for refrigerated, CRT, and ambient protection. It’s certified for direct food contact too, so one product line covers pharmaceutical, life sciences, and food-grade shipments alike.

Pick the thickness to the lane, refrigerated, CRT, or ambient. Same recyclable construction across all three.

1.0 inch
3.4R-value

The thinnest profile, lightest weight and most compact pack-out for shorter ambient lanes.

1.5 inch
5.3R-value

The balanced middle option for controlled room temperature shipments and most general cold chain lanes.

2.0 inch
6.2R-value

Maximum thermal resistance for refrigerated lanes and longer transit windows that demand more.

Key features

Flat to ship. Fast to fill.Curbside at the end.

01. OCC-E certified

OCC-E curbside recyclable certification

Recycled in the same bin as corrugated cardboard. No special drop-off required for recipients. This matters especially for direct-to-patient programs where end-of-journey disposal instructions need to be simple.

02. Flat-pack

Reduces inbound freight and storage

The liner ships flat and expands at the pack station. A significant reduction in storage footprint versus pre-formed EPS or EPP, multiple pallets of assembled coolers fit on a single pallet of flat-packed liners.

03. Fast assembly

Assembles at the pack station in seconds

The two-piece format assembles fast. No conditioning, no pre-forming, no warehouse prep. Drop in the PCM refrigerant, add the product, close the liner, seal the box.

Specifications

Performance You Can Measure, Recyclability You Can Prove

R-values your engineers can validate, and a recycling claim your sustainability report can stand behind.

Recyclable, spec-sheet ready.

Job

High-volume, single-use pharmaceutical and life sciences shipments that need EPS-level performance, with nothing left for the patient to do but dispose of the packaging in the recycling bin.

Operator

Ships flat to save storage space and cut inbound freight, assembles in seconds at the pack station, and comes in at a similar price point to typical foam solutions.

Who it's for

Who it’s for.

01

Sustainable packaging programs in specialty pharmacy

Direct-to-patient shipments that need to be curbside recyclable at the patient's door. The OCC-E certification supports sustainability claims without requiring a separate recycling program.

02

Procurement teams with ESG or EPR obligations

Paper-based insulation carries a significantly lower EPR fee liability than EPS in the EU, Canada, and US state programs. For teams tracking Scope 3 packaging emissions, switching to EarthWise Cellulose reduces the Category 1 footprint reported against purchased goods.

03

Lab & diagnostic sample shipments

Diagnostic labs and specimen shippers get the same performance, recyclability, and flat-pack economics for both collection and delivery, with a simple end for whoever receives it.
