Eco-friendly Bio-materials
Overview of Eco-Friendly Barrier Coating Agent "NEXRIER®"
NEXRIER®is a portfolio of nature-derived, water-based barrier coating solutions designed for paper and flexible packaging.
livers high-performance oxygen, moisture, and grease barriers while improving recyclability and supporting more sustainable packaging designs.
Realization of a Circular Economy
through Nature-derived Materials
- Creating added value through utilization of livestock byproducts
- Achieving 99% resource reduction by replacing with multi-material composites
Enhancement of Brand Value as an
ESG-leading Company
- Providing applicability for recyclable mono-materials
- Building consumer trust through eco-friendly technology development
Operational Optimization through
Reduced Fees and Cost Savings
- Securing price competitiveness against competing materials
- Reducing EPR (Extended Producer Responsibility) fees by avoiding the “difficult-to-recycle” grade
