New nanotechnology provides exciting opportunities for packaging

We came across this story today and are excited about the possibilities & opportunities that this could present to the packaging industry, especially in the area of ‘added-value’ electronic & ’smart’ packaging. At it’s heart is the discovery of a new way of splitting layered materials to give atom thin “nanosheets”. This has led to a range of novel two-dimensional nanomaterials with chemical and electronic properties that have the potential to enable new electronic and energy storage technologies. The collaborative* international research led by the Centre for Research on Adaptive Nanostructures and Nanodevices (CRANN), Trinity College Dublin, Ireland, and the University of Oxford has been published in this week’s Science. The scientists have invented a versatile method for creating these atom thin nanosheets from a range of materials using common solvents and ultrasound, utilising devices similar to those used to clean jewellery. The new method is simple, fast, and inexpensive, and could be scaled up to work on an industrial scale.

For decades researchers have tried to create nanosheets from layered materials in order to unlock their unusual electronic and thermoelectric properties. However, previous methods were time consuming, laborious or of very low yield and so unsuited to most applications.

“Our new method offers low-costs, a very high yield and a very large throughput: within a couple of hours, and with just 1 mg of material, billions and billions of one-atom-thick nanosheets can be made at the same time from a wide variety of exotic layered materials,” explained Dr Nicolosi, from the University of Oxford.
These new materials are also suited for use in next generation batteries – “supercapacitors” – which can deliver energy thousands of times faster than standard batteries, enabling new applications such as electric cars. Many of these new atomic layered materials are very strong and can be added to plastics to produce super-strong composites. These will be useful in a range of industries from simple structural plastics, through packaging, medical devices and even to aeronautics.

Key development in semiconductor technology provides breakthrough for electronic packaging

Semiconductor Research Corporation & Stanford Develop Unique Combination of Elements for Thermal Nanotape That Transforms Packaging Applications
Semiconductor Research Corporation (SRC), the world’s leading university-research consortium for semiconductors and related technologies, and researchers from Stanford University have developed a novel combination of elements that yields a unique nanostructure material for packaging. This advance should allow longer life for semiconductor devices while costing less than current state-of-the-art materials. In addition to chip manufacturers, several other industries could also gain greater product efficiencies from related thermal energy management technology.
For semiconductors, the improvement will come in the form of packaging for devices. Presently, manufacturers must rely on tiny pins or thick solder to bond sections of the semiconductor in order for the device to perform. However, current solder materials tend to degrade and fail due to heat and mechanical stress. In order to continue the scaling of integrated circuits, SRC and Stanford have researched materials that provide a high thermal connectivity — comparable to copper — with the flexible compliance of foam. The answer has been created through a nanostructured thermal tape that conducts heat like a metal while allowing the neighboring materials to expand and contract with temperature changes (metals are too stiff to allow this). This ability to reduce chip temperatures while remaining compliant is a key breakthrough for electronic packaging.

Professor Streckl & Duk Young Kim's research takes us ever-nearer to moving pictures on packaging

A breakthrough in a University of Cincinnati engineering lab that could clear the way for a low-cost, even disposable, e-reader is gaining considerable attention and this technology could have ‘far-reaching’ implications and provide all sorts of opportunities in the field of packaging, with the ability to ‘print’ moving pictures (of a quality seen on glass) onto flexible packaging.

Electrical Engineering Professor Andrew Steckl, together with UC doctoral student Duk Young Kim, have researched into an affordable, yet high-performance, paper-based display technology which has demonstrated that paper could be used as a flexible host material for an ‘electrowetting’ device. Electrowetting (EW) involves applying an electric field to coloured droplets within a display in order to reveal content such as type, photographs and video.

Steckl’s discovery that paper could be used as the host material has far-reaching implications considering other popular e-readers on the market such as the Kindle and iPad rely on complex circuitry printed over a rigid glass substrate. Steckl says: “It is pretty exciting. With the right paper, the right process and the right device fabrication technique, you can get results that are as good as you would get on glass, and our results are good enough for a video-style e-reader.”

He imagines a future device that is “rollable, feels like paper yet delivers books, news and even high-resolution color video in bright-light conditions” – perfect for packaging applications (in my opinion)! If you combine this with the Sony technology (Rollable OTFT screen) that we wrote about recently, the packaging possibilities are endless!

Here’s how ‘Eco Warrior’ and ‘Gaia Capitalist’ David de Rothschild made his catamaran ‘Plastiki’ out of recycled PET bottle packaging -- turning waste into resource and into an (almost) completely recyclable boat, that he then sailed from San Francisco to Sydney.

Plastiki - David de Rothschild's yacht made of recycled PET bottles

As we have discussed in previous posts, there is a huge and ever-increasing mountain of rubbish growing in the middle of the Pacific, like a giant festering ’soup’, much of which consists of plastic packaging waste. This has had a massive knock-on affect in the  form of polluted beaches on islands throughout the South Pacific. See our previous article: Great Pacific Garbage Patch article

David de Rothschild is a man on a mission. The offspring of the wealthy banking family, he is one of a new breed of environmental crusaders and entrepreneurs that some are calling ‘Gaia capitalists’. ‘Gaia’ in mythology was the primal Greek goddess of the Earth and aptly a ‘gyre’ in oceanography is any large system of rotating ocean currents (source: Wikipedia).

To highlight the Pacific issue and raise it’s profile in mainstream media, De Rothschild decided to use his family’s high profile  (& money) to build a yacht made entirely of recycled plastic bottle packaging, which he named ‘Plastiki’ (making reference and tribute to the late Thor Heyerdahl’s papyrus Kon-tiki raft which crossed the Pacific back in 1947). Over a four month period he sailed this 60ft catamaran from San Francisco to Sydney, where he landed last week. But his exploits are no shallow ploy to fill aimless days with fun and adventure.

De Rothschild and his ‘Gaia’ friends are driven by a combination of social conscience and economic pragmatism, seeking a ‘paradigm shift’ in the way we live and desecrate our planet. They espouse a new form of capitalism that factors in the environment and social wellbeing as a cost. It considers protecting the environment not only as a moral issue but as a set of design challenges to correct inefficiencies that make the capitalist system unsustainable. Waste, for example, is considered the result of inadequate thinking. If you are smarter about it, and create products that work properly, then you shouldn’t have to throw anything away at the end – should you? The group include Chad Hurley (33) who with his co-founder, sold YouTube to Google for $1.6Bn and has since ploughed some of his fortune into the Green Products Innovation Institute and Jeffrey Skoll, worth $2.4Bn, who wrote the business plan for eBay and has set up the Skoll Foundation to encourage ’social entrepreneurs’ to play a greater role in developing a better world (source: The  Sunday Times).

These are ‘game changers’, who see solutions where others see problems – a new entrepreneurial revolution – one of collaboration something that de Rothschild calls ‘Planet 2.0′. So I feel that we will be hearing a lot more from this ‘band of brothers’ in the future. They mean to ‘rattle some cages’, get us all to think differently and make a real impact by influencing things at ‘the top’. They have a point! Can we really carry on the way we are? For a really ’sustainable future’, for our children and their children’s sakes, things have to change a lot quicker.What do you think?

Traditional wine bottle cork packaging

There’s nothing quite like the ‘pop’ of a cork exploding from a wine bottle when it’s opened is there? For me, although screw thread or rubber closures do the job, they don’t quite have the same emotional appeal. Well, for those of you who have a similar opinion (94% of wine drinkers according to a survey of 1500), you will be pleased to hear that there is research available to backup the sustainable credentials of cork and its continued use in wine bottles.

According to the Portuguese Cork Association (APCOR) there are 3 misconceptions regarding cork stoppers, that are highlighted in a recent Packaging News article:

1. Trees are NOT cut down in the production of cork – they are harvested in a sustainable manner. In fact harvesting, if managed properly, actually guarantees a trees survival.

2. Screw caps are NOT the most environmentally friendly closure, as cork is 100% natural and renewable and apparently uses 10 times less carbon dioxide (CO2) emissions than plastic stoppers and 24 times less than screw caps.

3. Corked wine is (allegedly) is NO MORE of an issue with natural cork than tainitng is with other closure systems (although this has been very carefully worded by APCOR).

Medical device packaging

Traditionally medical products, devices and their related packaging has been ’sidelined’ in much of the debate around the environment, where the major focus has been on retail products. However, it is estimated (Mulligan) that medical packaging contributes between 30% to 50% (or more) of the medical waste stream. There is a lot of work going on in the background, within the National Health Service (NHS) in the UK, and further afield globally, as healthcare practitioners are put under increasing pressure to ‘go green’, become more ’sustainable’ and reduce their ‘carbon footprint’.  These initiatives go right to the core of their infrastructure, looking at everything from operating theatre furniture and equipment, through to medical devices and all related packaging.

However, there are wider ramifications, as it apparent that these sustainability initiatives will also enable huge cost benefits, improved regulatory compliance, and enhanced corporate social responsibility (CSR) when done correctly. So no pressure then !

On the face of it, this looks like a huge and daunting task, but with the aid of modern modelling techniques, such as those used by Walmart and by Marks & Spencer (M&S) in their ‘Plan A’, data and issues can be quite easily ‘chunked-down’ into manageable bite-size segments. This can help prioritisation and enable ‘quick wins’ on the highest ‘value creating’ initiatives.

It is important that suppliers and medical device manufacturers think about these sweeping changes and, if not already doing so, start to design and develop medical devices & healthcare packaging to meet these more stringent requirements. Next-generation packaging must be: 1) easy to manufacture; 2) meet stringent regulatory requirements; 3) meet the needs of distributors, healthcare institutions, and medical practitioners; and 4) minimize impact on the environment.

Mulligan talks in greater detail about all of this in an interesting article ‘Using a Life Cycle Analysis approach in medical packaging‘ recently published on the Healthcare Packaging website. Have a read and let us know what you think!

Apparently over 30% of food produced is wasted before being eaten

It is interesting to read that the focus of active and intelligent (A&I) packaging has shifted from “manufacturer concerns” such as shelf-life and spoilage to “consumer concerns such as freshness, quality and information”, according to recently published research.

The report – ‘The Future of Active and Intelligent Packaging in Food and Drinks’ said that industry leaders had identified “freshness indicators as the most important innovations in the field over the next five years. A development on quality was listed as the next most important field followed by temperature and time indicators.”

However, with over 30% of all food that we buy being wasted, I would hardly call “shelf-life and spoilage” just “manufacturing concerns”. They are huge and global concerns for everyone, much of which is to do with education and the role that packaging can play to save costs for everyone in the supply chain (very important in the present economic situation) but also, ultimately, to help save the planet’s finite resources.

I’m not sure how the research was conducted, what questions were asked, or how they were asked, but apparently, consumers ranked “health, convenience, safety and enhancing product attributes” as the most important attributes that would make them willing to pay more for A&I-packaged products. “Longer shelf-life and packaging that communicates product information” were also seen as important, but consumers perhaps see these as a ‘given’ and wouldn’t necessarily want to pay extra for them.

It is my feeling that the growth of A&I packaging has been primarily technology-led, by developments in sensor technology including nanosensors and biosensors. This is highlighted by the emerging trend of the incorporation of scavenging functions into packaging with bottles, labels or films. This is great technology, but I’m not sure that most consumers would understand what these are or what benefits they bring and therefore they would certainly not want to pay for their incorporation.

It is true that “Delivery of efficiencies in the value chain and the opportunity for manufacturers to differentiate their products and boost their efficiency by reducing product losses” will be major benefits for manufacturers and retailers – but what about consumers? There is a huge consumer-led marketing ‘trick’ being missed here, especially when “High production costs, compliance with food safety regulations and consumer mistrusts” are being highlighted in the report as “potential challenges”.

So, it is good to see that the consumer perspective is taking greater prominence (to some degree at least), in the New Product developments (NPD) that will help meet consumer needs in the expanding drinks and ready-meals segments. I agree, that the current focus for A&I has to be on luxury goods initially, and that it will move to lower-end products as the technology becomes more widely available and costs fall, but maybe it’s time to take a large ’step back’, flip this around completely and look at it from a consumers’ point-of-view. It is up to us all to educate consumers – highlight the wider issues of food (and water) waste & spoilage, get them to understand the more holistic effects of these on their daily ‘wants & (real) needs’ and ultimately get their ‘buy-in’ to the ‘real’ benefits.
