Ink-jet printed polyester and polyacrylate coatings for food packaging
Functional polymer coatings deposited by ink-jet printing for food packaging applications. The approach targets barrier, adhesion, and protective performance for both flexible and rigid packaging formats, using additive, digital deposition to improve design flexibility and material efficiency. Laboratory demonstrations support next-stage, industry-relevant performance evaluation.
Overview
This solution applies ink-jet printing technology to deposit functional polyester and polyacrylate coatings tailored for food packaging. Ink-jet printing is used to enable additive, digital deposition of polymer layers with design flexibility and material efficiency. The coatings are designed to meet food-contact packaging performance requirements, including barrier properties, adhesion, and protective functionality.
Technical specifications
- Deposition method: Ink-jet printing enables precise, additive coating of polymer layers without traditional roll-to-roll or solvent-heavy processes.
- Material systems: Functional polyesters and polyacrylates formulated as printable inks, with tunable chemistry for food-contact applications.
- Functional performance: Coatings developed to address food packaging needs such as barrier, adhesion, and protective functionality; specific performance metrics will be detailed at a later stage.
- Validation pathway: Planned testing with packaging-focused researchers to evaluate food packaging performance under industry-relevant conditions.
Technology readiness level
Functional polymer coatings meeting food packaging requirements have been demonstrated in laboratory settings. The next stage involves industry-relevant validation to assess real-world packaging performance, indicating a mid-stage development position moving from lab-scale demonstration toward broader testing and potential commercialization.
