Vitsab International AB has introduced Freshtag, a color-changing smart label that monitors time and temperature conditions for perishable foods along the supply chain.

The technology involves a surface-enhanced Raman scattering sensor integrated into stretchable and antimicrobial wrap. Potential applications span cold-chain logistics and storage, retail smart packaging, food safety monitoring, and meal kit delivery.

Polyethylene terephthalate (PET) is not flawless; no packaging material is. However, its long safety record, rigorous regulatory oversight, and strong sustainability profile make it a material worth defending.

EcoBio Barrier Paper is a recyclable, repulpable, and biodegradable option for moisture-proof and greaseproof packaging. It is made without intentionally added plastics, per- and polyfluoroalkyl substances (PFAS), or fluorochemicals.

The collection includes food boxes, bakery packaging, and takeout boxes made from FDA-approved, non-toxic, and grease-resistant materials.

Although elevated levels of some PFAS were found in the blood of people who ate more highly processed foods, people who ate minimally process foods showed elevated levels of other PFAS compounds—suggesting that dietary choices cannot protect people from “forever chemicals,” and that systemic solutions are needed.

A review published by EFSA concludes that, while there is clear evidence of microplastic release from food contact materials (FCMs), the actual quantities are likely lower than many studies suggest, and current evidence does not support reliable exposure estimates. Nanoplastics data remain insufficient.

This episode of Food Safety Five discusses a UK proposed ban on Bisphenol A (BPA) in food contact materials, as well as two studies with global relevance: a successful clinical trial for a novel Salmonella vaccine and research demonstrating how nanoplastics enter the edible parts of crops.

In his veto letter, Gov. Gavin Newsom said he agreed with Senate Bill 682’s goal of phasing-out “forever chemicals” from consumer products, but said the bill would sacrifice Californians' ability to afford household products like cookware.

Developed by an industry consortium led by Western Growers and the Canadian Produce Marketing Association, the Roadmap to Sustainable Fresh Produce Packaging offers pragmatic recommendations for transforming packaging practices, based in the holistic concept of “Functional Sustainability.”
