Antimicrobial packaging expertsAbout antimicrobial packaging
Most of the work on Halo goes onto the food itself. Twelve entries are edible coatings for produce and fruit, built from chitosan, whey protein, plant extracts or PHA, and a smaller set builds the antimicrobial into the film or onto the surface that touches the food. On Halo it spans five groups, including coatings for fresh produce, coatings for fruit and berries, and antimicrobials built into the film.
Stage of development. Work on antimicrobial packaging on Halo is split between university programs and companies. 81% are past proof of concept (TRL 4 or higher). Michigan State University has the most, followed by McGill University. Co-development and sponsored research are the usual partnering routes, and about 56% of the solutions that state terms offer pilot engagements.
Three trends in antimicrobial packaging on Halo
The coating goes on the food, not the package. Twelve entries are applied directly to produce or fruit: chitosan with gelatin, whey protein with aloe vera, PHA, plant extracts, nanofibers carrying bioactives. Only one puts the active in the pack and lets it work through the air, using volatile plant extracts to trigger the produce's own defenses. For most of these, the packaging is a film a few microns thick on the fruit.
Chitosan is the default chemistry. Chitin and its derivative turn up in at least seven entries across every cluster: paired with gelatin, with gum arabic and ionic liquids, with olive waste polyphenols, with AKD sizing, and with cellulose to match EVOH on oxygen. It is antimicrobial, it films, it biodegrades, and it comes from a waste stream, which is four requirements met by one material.
Most of it is early. Nineteen of the thirty entries sit at TRL 4 or 5, and several are university work seeking a partner. The two commercial exceptions are both from one company and both name a specific product, fresh meat and cocoa liquor, with validation behind them. There is a wide gap between what has been demonstrated on a bench and what a packer can buy.

Frequently asked questions
What is antimicrobial packaging?
Antimicrobial packaging covers packaging that acts on the microbes, not only on the air around them. It spans edible coatings applied to produce and to fruit, antimicrobial agents built into a film, coatings that treat a food-contact surface, and the chitin and chitosan chemistries that carry a barrier and an antimicrobial at once. Food manufacturers, packers and produce handlers are the buyers.
