Recycled Materials

High-quality greyboard and kraft paper made from 100% post-consumer recycled waste, reducing the demand for virgin pulp.

Printed paper color samples with soybeans and a green soy leaf

Soy-Based Inks

We replace petroleum-based inks with vegetable/soy inks, which release fewer VOCs and make the paper easier to recycle.

Innovative Plastic Reduction

Replacing traditional plastic components with smart paper engineering.
