Performance Attributes

Water Resistance

BiobarcTM makes pulped and paper products water-resistant, helping protect packaging contents from external moisture.

When tested on Kraft linerboard 80-220gsm, it achieves water resistance of 20-30g/m2 (Cobb 30 minutes according to ISO 535).

This makes it more water resistant than wax coatings.

Strength Increase

BiobarcTM also increases the strength of the base material, creating more durable packaging products.

We have data to prove it increases strength by 15% (Tappi/ANSI T826 Short-Span Compressive Test (SCT).

Oil & Grease Resistance

BiobarcTM has achieved an 8-10 on the 3M Kit test (TAPPI Standard Test Method T 559), opening up additional packaging applications.

We are investigating alternative test methods that are most suitable for waterborne paper coatings.

Sustainability Attributes

Repulpable

Earthodic coatings allow a high percentage of paper or cardboard fibre to be reclaimed during the repulping process.

So far we’ve achieved 97.1% fiber yield on a standard 205gsm (42#) linerboard. Western Michigan University has tested BiobarcTM according to the Fibre Box Association (FBA) Voluntary Protocol Part I.

Recyclable

The high fibre yield and low sticky count we’ve achieved for repulped BiobarcTM coated products contributes to their recyclability.

Western Michigan University has tested BiobarcTM according to the Fibre Box Association (FBA) Voluntary Protocol Part II.

Compostable*

Unlike some other coatings like wax, compostable coatings allow pulped and paper packaging to naturally decompose into compost.

Our coatings fully broke down in our internal compostability tests. And we’re in the process of getting third-party tests for both home and industrial compostability.

100% Biobased carbon

Our products are made from abundant, renewable bio-based sources like lignin. So no fossil fuels are needed to create them.

All our products are certified as 100% bio-based carbon by the USDA BioPreferred program.

PFAS Free

Our products are free from harmful PFAS chemicals.

They’ve been third-party tested according to the Total Oxidisable Precursor Assay (TOP).

VOC Free

Earthodic products are also free from Volatile Organic Compounds (VOCs) or Hazardous Air Pollutants (HAPs). 

They’ve been third-party tested according to EPA Method 24 and Method 311.

Vegan

We don’t use any animal products. And no animals are harmed in the manufacture of our products.

Industry perspectives

“The excellent water resistance at low coating weights is a great combination, particularly in some of our seafood industry cold chain packaging solutions where Woolpack is actively displacing Styrofoam boxes with a greener and more sustainable solution.”
