Their research was published in the prestigious journal Advanced Materials IF:25.809 earlier this year: "A Self-Healing Nanofiber-Based Self-Responsive Time-Temperature Indicator for Securing a Cold-Supply Chain." This cold-chain safety sticker creates an image on it when exposed to room temperature (10 0C or higher). Room temperature exposure history and time throughout the cold chain delivery process are indicated but cannot be manually edited. When refrigerated or frozen foods are exposed to room temperature, usually bacteria begin to grow and reproduce. However, it is difficult to see visually as certain bacteria do not affect the taste and smell of foods and frozen foods have almost the same appearance even after melting and refreezing. The core technology of the cold-chain safety sticker is nanofibre film. The researchers attempted to attach a typical film on the back of this newly developed film. At low temperatures, the nanofibre film has a stable structure where thin threads intersect each other, making it opaque because the light is scattered. When exposed to room temperature for a period of time, this structure collapses. Specifically, the thin threads start to melt and become entangled with each other. This allows light to transmit through the film, making it appear transparent. Then the image produced on the typical film on the back becomes visible from the front, showing that the food may have spoiled. The researchers found a way to control the time that is required for the film to become transparent when exposed to room temperature, accounting for variations in spoilage times of different foods. So each sticker was designed to become transparent after a minimum of 30m and a maximum of 24 hours of exposure. This was achieved by controlling the composition and thickness of the nanofibres. Dr Dongyeop Oh from the KRICT said, "This sticker, once exposed to room temperature, cannot be restored to its original state, even if one attempts to refrigerate or freeze it again. Also, room-temperature exposure time cannot be manually adjusted. This means that there is virtually no room for any manipulation." “It does not require modularization, accurately measures localized or gradient heat and functions even after crushing, cutting, and when weight?loaded in a manner that existing TTIs cannot. It also contains no drainable chemicals and is attachable to various shapes because it operates through an intrinsic physical response,” he added. The cold-chain safety sticker can be widely used not only for food product applications but also for the cold-chain distribution of expensive medicine and medical supplies, they say. This is because the sticker is thin and flexible. It is estimated manufacturing cost is low at one cent per unit.
Mondi, a global leader in packaging and paper, has introduced its first recyclable functional barrier paper bag for salads in the Group LSDH’s Les Crudettes range. The sustainable packaging is a fully integrated solution – Mondi operates across the value chain from sustainably managed forests, to producing pulp and kraft paper, applying the coating and printing the final material.
The French salad brand has replaced its transparent glossy polypropylene (PP) packaging with Mondi’s recyclable functional barrier paper for a selection of its pre-washed, ready-to-eat salads. The new packaging is 95% paper with a functional barrier layer, meaning the salad remains fresh for up to 10 days - the same amount of time as with the previous plastic packaging. It is verified as recyclable in the waste paper stream in France by the Recycling Authority (Cerec).
The bags are flexoprinted, with lifelike depictions of the salad contents on the front, along with a QR Code, which informs consumers about the contents, quality, recycling and even refund policy, if they happen to purchase a bag where the contents are not as fresh as expected.
Using its unique EcoSolutions approach, Mondi worked closely with LSDH, and its machine supplier Ilapak, to ensure that the new packaging is fit-for-purpose and can run on existing machines. The new solution is sustainable by design, and will support LSDH Group in meeting its sustainability goal of reducing the amount of plastic in its packaging.

HISTORIC FLAVOURS WITH A MODERN TWIST
Produced from 100% Italian pork, Chiola’s mission is to provide meat lovers with a simple but excellent flavor experience. Chiola introduced its new fresh meat range on the Italian market which includes burgers, fillet medallions and selected slices of pork loin.
The brand wanted the new products to not only stand out on shelf, but also reflect their longstanding family values of looking after people, animals and the planet.
Working with Amcor, Chiola conducted a lifecycle assessment to find the best packaging solution. The results showed that Amcor’s VAC™ and ICE™ custom-engineered forming films, combined with a paperboard exterior wrap, would provide an 80% reduction in plastic and 65% reduction in overall packaging carbon footprint.
Of course, for meat products, freshness and food safety are top priority. Our specialized meat packaging team developed a solution with Chiola that offers the utmost safety and enhanced freshness for meat products, which ticked all the boxes for Chiola.
The brand's new, more sustainable packaging continues to offer high standards of food safety and product enhancement, as well as giving the products a contemporary look and feel that appeals to customers shopping for high-quality meat.

Assessing the risks from 'grease-proofing' chemicals in food packaging requires new methods, studiesNews:
Exposures to some of the 4,000 or so members of the per- and polyfluoroalkyl substances (PFAS) class of chemicals have been associated with potential adverse health effects such as high cholesterol, low infant birth weight, reduced antibody response to vaccines and high blood pressure. While environmental studies of PFAS have advanced, gaps remain in our understanding of how much humans are exposed to PFAS from food and packaging, and the associated risks, if any.
This prompted the Institute for the Advancement of Food and Nutrition Sciences to sponsor a symposium titled "Identifying Science Gaps for Risk Assessment of Per- and Polyfluoroalkyl Substances in Food." Given the importance of measurement systems, the symposium first focused on analytical methods and science gaps for detection and quantification of PFAS in food. Additionally, presenters addressed exposure routes and detection in foods—including FDA and USDA work in the area—and touched on potential effects of short-carbon chain replacements for longer-chain biopersistent PFAS.
The symposium proceedings were recently published in Trends in Food Science & Technology, a peer-reviewed journal. Some of the challenges involve understanding which products have intentionally added PFAS versus incidental environmental contamination from processing waste. Moreover, future method validation is needed to develop standard approaches for extraction, screening and quantification of PFAS compounds. Continuing to develop methods will support FDA's and USDA's ongoing monitoring of PFAS in produce, dairy, meat and bread. But the absence of validated, standardized methods makes it difficult to compare results and poses a challenge to risk managers here and abroad.
There are still many knowledge gaps on risks associated with PFAS, but risk management efforts need to be supported through analytical testing by the adoption of international performance standards and the development of official compendial methods, according to speakers at the symposium.
By providing more TerraCycle public drop off locations, and with the continuation of ACE-UK Bring Banks taking containers with metal ends*, the aim is for consumers to be able to recycle in up to 85% of council areas across the UK.
Kellogg’s said it aims to have 700 TerraCycle recycling points in addition to the existing 330 ACE-UK Bring Bank collection points, by January 2022.
This is an increase from 57% of UK council areas which currently has easy access to drop off locations for Pringles.
To help its shoppers recycle their Pringles tubes there will be a new on-pack recycling label that highlights the tube can be recycled at a collection point and the lid in the home recycling bin.
The empty tubes from both collection schemes will be taken to a specialist recycling facility in West Yorkshire, operated by Sonoco Alcore, where the fibres from the recycled cartons will be turned into industrial tubes and cores, which are used to wrap paper, man-made fibre yarns, and metal and plastic film around for industrial applications.
Helen Potter, sustainability lead for Pringles, said: “We want to do more to help people recycle their Pringles packaging as we continue to work on the development of a new tube. At Kellogg we are committed to making all our packaging recyclable, reusable or compostable by the end of 2025. This is another great step forward.”
Julien Tremblin, general manager, TerraCycle Europe said: “We are thrilled that Pringles have made the decision to expand the number of drop-off locations available to consumers. This programme has proved very successful and it is great to see a brand taking the issue of waste seriously and offering a viable solution to their shoppers.”
Last year Pringles also trialled a new tube made of recycled paper which was widely recyclable in home recycling bins.
