Smart packaging technologies extend shelf life and connect dairy products
- 1. Smart packaging - From the shelf and dairy case to the internet of things Gail Barnes PhD, Partner, Personify LLC Active and Intelligent Packaging Association (AIPIA) Congress, (Nov. 2–4) during Pack Expo International and Pharma Expo 2014 (Nov. 2–5), McCormick Place, Chicago, IL.
- 2. Summary A major trend feeding the growth of active and intelligent packaging for dairy is the demand for longer shelf life. For retailers this demand results from product loss due to shrink, which includes product going out of date code, which runs at between 2-5% in the United States. Addressing shrink by adding even a few days shelf life through Extended Shelf Life (ESL) technologies including UV photopurification, could save retailers hundreds of thousands of dollars a year and thus help to increase the profitability of the category. For consumers the demand stems from an increasing desire for fresh and unaltered foods. In addition to standard ESL technologies, RFID tags by enabling the accurate tracking and tracing of product throughout the supply chain could play a role in both increasing efficiency as well as increasing sustainability. Printing with thermochromic inks could indicate if a product has suffered temperature abuse as well as the best temperature for consumption by consumers, while biosensors could indicate if a product has spoiled and should be discarded. Printable electronics will lower the cost of technology as such biosensors or RFID tags. This presentation will cover the impact of these technologies through the use of case studies and industry concepts and examples from around the world.

- 5. Dairy Lost By Shrink • Shrink, whereby a product has to be disposed of because it has gone out of date code, is a major issue for processors & retailers • Estimated to be around 2-5% for white milk in the US • Major source of food waste in the dairy industry • Requires a holistic approach to address – Processing – Packaging – Distribution Source: Dr Tatiana Koutchma & Dr Gail Barnes, The Potential for UV Illumination as an Adjunct to Pasteurization, IDFA Conference on Worker Safety and Environmental Issues, May 29-30, 2013, Chicago, IL.
- 6. Processing Innovation To Extend Shelf Life • Combine non-traditional technologies with traditional pasteurization • UV photopurification can extend the shelf life from around 14 days (in the US) to 30/60/90 days depending on the product type
- 7. Packaging Innovation To Extend Shelf Life • Minimize/eliminate recontamination – Clean blow technology for producing plastic bottles – Consumable, pressurized liquid instead of compressed air to form plastic containers • ESL/UHT packaging/fillers – HEPA filters – Over pressured air – UV lamps – E-beam sterilization
- 8. Smart Packaging Innovation • Thermochromic inks • Indicators/sensors • RFID • NFC
- 9. Thermochromic Inks • Are inks that become visible only at certain temperatures • Are supplied as two components (both water based) as: • Active temperature sensitive product • Carrier resin for printing • Typical options suitable for beverage consumption purposes: • Fully activated at 5oC and below (not a standard product) • Fully activated at 8oC and below
- 10. Carton Package Case Study • In the converting process a penguin and snowflake were printed onto aseptic cartons (ambient distribution and merchandising) • No color visible at ambient temperatures • When placed in the refrigerator and upon reaching 5oC, the penguin and snowflake would appear along with a message: “Perfect to drink” • Placed first against an array of innovations that included the soda dispenser from the Space Shuttle
- 11. Indicators/BioSensors • Detect temperature abuse • Validate that the cold chain is working • Electronic storage of reading data for analysis • Validate incoming goods • Create extra awareness on maintaining the cold chain • Cost efficient and commercially available
- 12. Thin Film Sensors • Thin Film Electronics prints “memory” on polymer-based substrates instead of using silicon and chips • This powers Thin Film's Smart Labels, which are economically produced on roll-to-roll machinery in amounts of thousands at a time
- 13. Radio Frequency Identification (RFID) • RFID is a technology that incorporates radio frequency to uniquely identify an object • The advantage of RFID is that it does not require direct contact or line-of-sight scanning and can read many tags simultaneously • System consists of three components – Antenna – Transceiver (Antenna / transceiver often combined into one reader) – Transponder (Tag, also called Electronic Product Code (EPC) tag) • Can be either active (own power source/broadcast up to 100m) or passive (no power source/powered by a reader with a read range from near contact up to 25m)
- 14. Getting RFID Right • Products react differently in a RF field • Two different locations on a single box yield very different results based on the RF properties of the product • Need to use scientific testing tools to determine profile of the product(s) • No single answer, different product configurations demonstrate a continuous spectrum of performance Source: Odin Technologies
- 15. RFID Applications • During the manufacture of packaging material – Tests with RFID labelled board reels in converting factories – Co-operation between RFID label producer Rafsec and board supplier Stora Enso • The pallet / container • The traded unit • The consumer unit
- 16. Hospital Vending Machine Dispenses Fresh Foods Via RFID • The refrigerated vending machine has a built-in RFID reader to identify which food items consumers have removed from its shelves • University of California, San Francisco Medical Center's nutrition and food services department and Stanford Health Care each piloted a refrigerated kiosk
- 17. Printed RFID Chips • Chips based on printable organic semiconductors • Printed on labels or directly onto the packaging • E-beam technology is the “missing link” for printing chips directly onto packaging – allows adherence
- 18. Near Field Communication (NFC) • Operate at same frequency as HF RFID readers and tags • May act as both a reader and a tag • Devices must be in close proximity due to short read range • Used for information sharing and contactless payment

Editor's Notes
- The table shows the annual total value of retail shrink in the US to be almost $112 million dollars. In addition to the dollar value, there is also the environmental burden as a result of the need to dispose of product, packaging etc. While it cannot be expected that an extension of shelf life as a result using UV illumination as an adjunct to pasteurization will address all the liquid milk that is currently lost to shrink, there is a potential for savings to be made and for waste and the resultant environmental impact to be reduced. How large this potential is, will be able to be determined as the results from pilot studies are obtained.
- Time Temperature Biosensor ™ (TTB™ ) from Swedish company Bioett Combines biotechnology with RF electronics Measures the accumulated temperature load Offers a cost efficient management tool First patent approved in USA and EU www.bioett.se Customers more and more demanding on product quality Temperature reading at every delivery to the retailers An unbroken cold chain is more important when handling products with added value Hence dairy quality system requires stricter control than normal Variations in the cold chain were detected Areas for improvements were identified, both at dairy and in the supply chain Bioett system worked well Good repeatability in reading data, information system made analysis easy
- Hospital vending machine dispenses fresh foods via RFID The refrigerated vending machine has a built-in RFID reader to identify which food items consumers have removed from its shelves. This spring and summer, the University of California, San Francisco Medical Center's nutrition and food services department and Stanford Health Care each piloted a refrigerated kiosk to determine whether they could use the system to provide fresh foods and cold drinks to employees and visitors, even when staff members were not available to sell the product personally. "Our operations have used traditional vending machines for years," said Charles Davies, the UCSF Medical Center's associate director of operations and culinary innovation. "With the use of RFID tags we now have expanded our vending options to fresh refrigerated food," he said in the article. The medical center is open 24 hours a day, while its café closes at night, leaving personnel and other customers with few food options except those items sold in vending machines after business hours. - See more at: http://www.healthcarefacilitiestoday.com/posts/Hospital-vending-machine-dispenses-fresh-foods-via-RFID-Maintenance-and-Operations--6176#sthash.I4Pcz96c.dpuf
- CPG brands must make personalized content and localized digital activation a priority if they want to influence in-store sales in an increasingly multi-screen environment, according to a new report from Gannett division G/O Digital. The CPG Marketing Reinvented report found that localized digital activation has a bigger direct marketing sway than television ads for CPG brands. Key findings include that 35 percent of moms and 29 percent of dads say the most frustrating thing about online and mobile ads is when the content is not locally relevant to in-store products and prices. “It’s surprising to see that deal content distributed across digital channels flexes more direct marketing muscle than TV ads,” said Jeff Fagel, chief marketing officer at G/O Digital. “As smartphone usage, DVR adoption, binge TV watching and cable cord cutting become more of the norm, it will be more important than ever for CPG brand marketers to leverage data to tailor marketing efforts, locally,” he said. “This is, in my opinion, the true opportunity for marketers – to scale local marketing.” The report is based on a survey of 1,000 online and mobile users in the United States that was conducted this summer between July 2 and July 9. Mobile is a behavior Pointing to the number of devices consumers use throughout their day, the report’s recommendations include that CPG should approach mobile as a behavior and not a channel while leveraging personalized promotional content and real-time localized digital activation at scale. Findings include that 79 percent of moms and 75 percent of dads are more likely to make in-store purchases when presented with locally relevant and personalized deals. Additionally, 32 percent of moms name digital circulars as the most influential advertising medium for influencing their in-store food and beverage purchases. Similarly, 29 percent of dads say the same thing. However, TV ads only influence the in-store purchase decisions of 6 percent of moms and 13 percent of dads. The report points to how mobile helps bring deals and in-app promotions into the store, with 19 percent of moms saying they regularly check Web sites, mobile sites and apps for promotions and deals when in-store while 36 percent say this is somewhat important. “Mobile is perceived as a hero for shoppers, but all marketers must approach mobile as a behavior (not a channel) and strive for real-time localized digital activation at national scale,” Mr. Fagel said. “The lines between online and offline shopping have not only blurred; they’ve begun to disappear altogether,” he said. “While retailers and brands often focus on what’s ‘sexy’— iBeacons, geofencing and other technologies — we need to consider how consumers already interact with their devices and take advantage of that behavior.” Facebook beats Twitter The report are underscores how consumers are increasingly researching sale items online before they shop for groceries, with 40 percent of moms saying this is the first thing they do. Online and mobile deals also influence which supermarket consumers visit with 60 percent of moms and 50 percent of dads saying they would be very inclined to visit a local supermarket that advertises the lowest prices and deals. Another key finding is that Facebook beats Twitter as the most useful media channel to engage with CPG brands, with 55 percent of moms and 47 percent of dads pointing to Facebook while only 5 percent of moms and 7 percent of dads find Twitter useful. Additionally, 77 percent of moms and 72 percent of dads say localized deals and offers on Facebook are important enough to affect the food and beverage items they drop into their grocery shopping carts. “First and foremost, invest in the mobile experience,” Mr. Fagel said. “Part of this means marketers need to stop getting bogged down by tactics — like launching a mobile-optimized site or fancy app. “Today’s consumers switch screens as much as 21 times per hour,” he said. “On top of having shorter attention spans, consumers have even less tolerance for experiences that interrupt their native user experiences and worst of all, don’t match their needs in real-time. “There are a countless number of marketing tactics being thrown at consumers in a day – from emails and newsletters, to weekly ads, coupons and special offers. What needs to take precedence over everything when devising marketing strategies is the experience – from the consumers’ mindset, not the brand’s perspective.”
- Mobile ordering startup YesTap has installed an NFC-based interactive shopping wall at Google’s Amsterdam offices which lets employees tap to order groceries and make a payment on their mobile device before collecting the items at the end of the day. The interactive wall is a 60-inch TV that displays pictures of a range of meals, each with their own NFC tag. When tapped, the meal gets added to the consumer’s mobile cart and details such as the ingredients and preparation instructions can be viewed in the mobile app. The groceries, which are pre-packaged in the exact quantity to cook the dish, are supplied by specialist grocer and delicatessen Bilder & De Clercq. “We created an effortless user experience; tap the NFC tag to download the app or find it on the Play Store, enter credit card information once and then, from there on, they can continue to order and pay so it’s a simple tap and go solution,” Kenneth Yip, a co-founder of YesTap, told NFC World+. “We overlaid, on top of the TV, the NFC elements so it’s not directly infused within the TV, it’s a frame that sits seamlessly on top,” he explained. “We also have the technology that allows for the interactive wall to be updated through our web portal. “We have a system where our grocery partner can update the images that would then be reflected on the mobile device and it all synchronizes together so we know which image corresponds to which NFC tag and the mobile device then interacts accordingly. “Right now, it’s going well and there’s no indication for when this will be coming to an end,” Yip added. “They love how they can order the meals with this level of convenience. The fact that they can just simply tap and select the items from their mobile and pay, get it delivered to the Google office for them to pick it up before they leave, it’s a great experience and very practical.” YesTap also worked with Vodafone in Amsterdam to provide a mobile ordering and payment solution using a mobile app earlier this year. NFC tags were attached to shelves around Vodafone’s self-service cafeteria next to food items so that employees could tap the tags to add items to their cart as they go. “We are looking to partner with catering, fast food and point-of-sale companies to really disrupt the food service market with our mobile technology,” Yip added.
