Biobased and biodegradable multilayer spray coating for packaging
B4Plastics introduces a biobased, biodegradable spray coating for fiber-based packaging, enhancing water and oxygen barriers while ensuring compostability. This glue-free application improves sustainability without compromising packaging integrity.
Overview
B4Plastics has developed an innovative biobased and biodegradable spray coating designed to enhance the barrier properties of fiber-based packaging. This cutting-edge solution consists of polymeric particles dispersed in water, forming a uniform coating layer upon drying. The coating ensures high barrier protection against water vapor and oxygen, meeting stringent WVTR and OTR requirements. With over 70% biobased content and proven biodegradability, this eco-friendly coating offers a sustainable alternative to traditional packaging solutions.
Technical specifications
Key features:
- Biobased content exceeding 70%, ensuring environmentally friendly packaging
- Readily biodegradable polymer particles, with demonstrated home compostability
- Customizable barrier properties through adjustable layer thickness and deposition strategies
- Excellent adhesion enabling glue-free application on fiber substrates
- Compatibility with existing spray coating equipment and fiber repulping processes
Technology readiness level
This technology is currently at TRL 5, having been validated in relevant environments. Initial tests confirm its compatibility with current spray coating equipment, and further validations are underway to optimize its performance and scalability for industrial applications.
About B4Plastics
B4Plastics is a Belgian biopolymer technology company founded in 2014 that specializes in the research, development, production, and licensing of renewable, recyclable, and biodegradable materials [2, 6, 7]. The company designs materials using proprietary bio-based building blocks to create customized plastic alternatives that offer high mechanical strength while maintaining controlled degradability [1, 2, 6]. Its technology platforms, such as FortePlastics and TriggerPlastics, are engineered to address the global plastic waste crisis by providing sustainable replacements for fossil-based polymers in various industrial applications [5, 6].
By offering services ranging from laboratory-scale material development to industrial-scale production and technology transfers, B4Plastics helps manufacturers transition their portfolios to more ecological standards [1, 2]. The company works with various partners to integrate these bio-materials into end-products, including items like brooms and fiber-based packaging [1, 6]. Its approach emphasizes circularity—either by designing materials to be recycled or by ensuring they break down in specific environments without leaving microplastics behind—thereby helping customers meet sustainability goals and regulatory requirements [1, 6, 8].
