Graphene in Food Packaging
Graphene is being researched for food packaging because a well-dispersed graphene layer can slow the passage of oxygen and moisture, two of the main causes of food spoilage. We supply graphene already dispersed in water, solvents and resins for packaging developers who want to test it in films and coatings.
Where graphene is being explored in packaging
- Barrier films and coatings: graphene in polymer films and coatings to reduce oxygen and moisture transfer, with the aim of longer shelf life.
- Stronger, thinner packaging: graphene in polymers is studied for strength at lower thickness.
- Smart packaging: printed graphene sensors that could track temperature or humidity along the supply chain.
Future project: graphene shipping containers
Graphene-enhanced shipping containers for food transport are a future project, not a product. The idea is to use graphene's barrier and thermal properties in container materials to help protect food in transit. We have no test data on this yet.
What we can and can't claim today
We don't yet publish test data for graphene in food packaging. Any material that touches food must also meet food-contact regulations before use.
Our verified results so far are in other materials, such as a 67% gain in concrete compressive strength at about a 1% dose and four graphene car care products developed with ITW for Rain-X and Black Magic (ITW case study).
