Barrier science for fiber packaging
A better barrier,
built for fiber.
Greenshoot’s cellulose-based coating technology is designed to improve moisture, oxygen, and grease resistance while supporting biodegradable food packaging.

A thin coating.
A meaningful shift in performance.
BIOXELL can be applied to almost any fiber-based packaging to create a functional barrier between food and the underlying fiber packaging. This coating is designed to replace traditional plastic barrier coatings to limit moisture, oxygen, and grease transfer while enabling a biodegradable packaging system.

Grease resistance (KIT test)
<5 cc/m²/24 hr
Oxygen permeability
Performance figures are carried over from Greenshoot Materials’ current technology information. Final performance depends on substrate, coat weight, package design, and test conditions.
Built for fiber
Performance that begins at the surface.
Barrier protection
Designed for moisture, oxygen, and grease resistance.
Packaging functionality
Applicable across formats including to-go containers and pet-food packaging.
Material intent
Plant-based, non-toxic, PFAS-free, and designed for biodegradable fiber systems.
From feedstock to afterlife
A production path designed to come full circle.
Greenshoot’s process moves agricultural side streams through mechanical processing, formulation, and industrial coating to create functional fiber packaging. The intended material pathway continues beyond use—through appropriate composting conditions and back toward soil.
