Sugarcane is one of the world’s most renewable resources. Grown in Brazil’s climate, it regenerates quickly after harvest and captures CO₂ during its growth cycle. That means BioMax™ packaging begins with a raw material that is not only renewable, it is actively helping to reduce greenhouse gases.
Unlike fossil fuels, our plant-based feedstock contributes to a more balanced carbon cycle.
We offer full shrink sleeve label design services to help your brand stand out on the shelf. Our team will work with your artwork or create something from scratch to produce high-impact labels tailored to the shape and size of your BioMax™ jars.

Unlike traditional petroleum-based plastics, this renewable material captures CO₂ during its production cycle, helping reduce your carbon footprint while maintaining performance and safety.
