Developers of an eco-friendly packaging coating made from starch and clay designed to replace plastic films are seeking partners to market the idea.
Scientists from Sheffield Hallam University (SHU) in England and Karlstad University in Sweden said CaiLar, which is made from starch and clay, has been designed to encourage the use of natural based packaging. The team said the clay-starch-plasticiser combination maximises moisture and oxygen barrier properties while under normal conditions.
A board substrate without any coating had a water vapour transmission rate (WVTR) of 340g per square metre per day, which was reduced to 260g per square metre a day after adding two individual layers of the starch and plasticiser.
Stora Enso expands its selection of biodegradable packaging boards
Stora Enso is meeting the growing demand for biodegradable packaging solutions by expanding its selection of biopolymer-coated packaging boards. Biodegradable coating options are available for a number of the company's board grades for use in cups, plates, trays and folding cartons. The paper cups used at the Finnish Pavillion at the current World Expo in Shanghai are made from biodegradable Cupforma board.
Stora Enso has developed biopolymer coatings for years. "Our patented biopolymer coating technology has enabled us to develop the barrier and other material properties so that the requirements of various end use applications can be met," says Kiviranta. "Based on our experience from our long-time cooperation with cup producers, converting biopolymer-coated boards is more demanding than usual but doesn't require investments in new machinery."

On the other hand, Brazil has unique competitive advantages for the local bioplastics production. Brazil is the leading producer of sugarcane in the world, having the lowest production costs for this raw material. The constantly growing production of sugarcane in Brazil will drive the country's bioplastics production based on ethanol.
The main applications for bioplastics in Brazil are the segments of food packaging (rigid and flexible) and agriculture films and disposals. In agriculture, disposables for accommodating seeds during planting are being used.
Plastic handbags are also an important application for bioplastics in Brazil.
Expected Movements in the Industry
For 2015, large scale units are expected to be producing bioplastics in Brazil, such as Braskem bio-based polyethylene (200,000 MT per year) and Solvay bio-based PVC (120,000 MT per year). Braskem bioplastics plant will be the largest in the world. This substantial change in the market will result in a rapid growth in the bioplastics market in Brazil, which is expected to value more than $600.0 million by 2015.
Braskem is the largest petrochemical company in Latin America with revenues of more than $12 billion in 2009, and entered into bioplastics production in 2007, manufacturing a product called 'green polyethylene'. The project to produce 200,000 MT of bio-based PE is expected to be completed in the fourth quarter of 2010. The technology used for green PE manufacturing ethane, the raw material to make plastics, which can be manufactured by removing one water molecule (H2O) from sugarcane ethanol through dehydration process. In the end, the plastics produced have the same characteristics as conventional plastics derived from fossil feedstock, such as naphtha or natural gas.
Frost & Sullivan expects that bio-based and petrochemical plastics will coexist in the market. In the short to medium term, bioplastics are not considered a threat to petrochemicals, as its volumes will correspond to less than 5% of the total plastics' demand. While bioplastics will be focused on premium products, where biodegradability or compostability is an added value, conventional resins can focus on applications where low price is required or when improved technical performance (thermal and mechanical properties) is crucial.
Bioplastics's prices are expected to decrease by 20 to 25 percent in the next five years. This rate is highly influenced by the new capacity of bio-based PE that will come into the market in Brazil. Bioplastics are likely to be a fast growing market in Brazil, with production process rapidly dominated. On the other hand, petrochemical plastics' prices are expected to rise in the next years, following the growth in global demand and the increasing oil prices.
In the medium and long terms, bioplastics will have to identify applications where they can bring in genuine performance advantages over conventional plastics, rather than just being beneficial from the point of view of ending disposal. Promising applications for the future include: medical devices, construction (furniture), footwear and others. Nevertheless, the major applications continue to be food plastic packaging, agriculture, and consumer products.
Market Opportunities for Bioplastics in Brazil
Brazil represents a valuable opportunity to explore the production of plastics from renewable resources, as it has a competitive advantage over other countries regarding production costs.
The Brazilian production of bioethanol based on sugarcane is much more efficient than the U.S. production based on corn.
Competitive production scales and an increasing demand will be crucial to make bioplastics a growing and profitable market in the region. Legislation and government incentives, currently under development, are also considered important in this stage of the industry, leveraging small local companies.
Due to the price premium required for bioplastics over conventional plastics (30 to 70 percent higher), a major challenge to the market participants will be convincing new end users to use the products. As a result, the strategy of marketing and product positioning will be critical to the product's success in the market.
Success factors for the implementation of bio-based plastics

The chemical, which is in the highest toxicity category because it poses a "particularly severe risk to health", is found in high levels on some of the sticky labels placed on packages of fresh meat, vegetables, tubs of sauce and other foodstuffs.
Strict EU safety regulations govern which materials can come into direct contact with food, but there are no rules about the chemicals in adhesives used to fix labels to the packaging.
A study published today by the Royal Society of Chemistry shows that four toxic compounds in commonly-used glues on sticky labels can seep all the way through paper and plastic packaging and contaminate the food inside.
One such adhesive is in the "highly toxic" class along with other poisonous chemicals such as mercury, asbestos and hydrochloric acid. Highly toxic chemicals can cause organ failure and even death in high doses.
The researchers, from the University of Zaragoza, Spain, studied four different acrylic adhesives commonly used on food labels.
They examined in detail 11 compounds found in the adhesives, ten of which had low toxicity while the remaining compound – 2,4,7,9-tetramethyldec-5-yne-4,7-diol – belonged to the highest risk category.
The team placed the adhesive on to a layer of polymer or paper covering the food stimulant Tenax to measure whether it was capable of penetrating the packaging.
Valérie Guillard, an expert in food technology at the University of Montpellier, France, said: “This work brings significant breakthroughs in the study of compliance with regulations of food contact materials.” She believes the research shows that “migration of adhesive compounds is possible and at a level that could raise safety concerns”.
The Food Standards Agency said the findings highlighted "a potential area of further research" as part of its "horizon-scanning for developing risks".
But a spokeswoman said: "Our own research has found that although several chemical substances are present in adhesives, the potential for them to migrate into food is very low."

The focus of active and intelligent packaging has moved from specific retailer and manufacturer driven benefits like shelf-life extension and spoilage protection, to include more consumer focused benefits such as freshness, quality and information. A range of diverse technologies and sectors are now relevant for active and intelligent packaging in food and drinks.
In the survey carried out for this report, 85.3% of executives stated that active and intelligent packaging will have ‘some’ or ‘a large’ impact on innovation within the food and drinks sector over the next five years.
According to the industry survey, freshness and quality indicators, temperature and time indicators, flavor and aroma releasing technologies, natural antimicrobials, self-heating and cooling technologies, were identified as the most important innovations for consumers over the next five years.
Food safety and traceability, food wastage and environmental concerns are influencing the uptake of active and intelligent packaging technologies in the food and drinks sector.
9% of all new food and drinks products launched over the period 2006 to 2009 were tagged with ‘fresh’, ‘freshness’, or related terms. 3.2% of new products launched were tagged with the term ‘quality’.

3. Considerable investments have been made by the global bioplastics industry and high growth rates result from a continually increasing market interest. This has continued even through the currently difficult economic situation and is expected to continue. (see graph 1)
4. The term “bioplastic” today can also cover commodities like PE or PET which can be fully or partially bio-based and perfectly recyclable – in exactly the same way as fossil-based PE or PET. However the bio-based content can lead to an increased degree of sustainability.
5. “Older” bioplastics have been in the market place for decades due to their excellent application performance, e.g. certain types of polyamides and PUR or cellulosics – without causing any significant issues for recyclers.
6. The recycling industry has found workable solutions to handle a huge variety of post-industrial and post-consumer plastic waste. The existing sorting and processing technology can handle bioplastics either without or with slight adaptation to specific material characteristics.
7. In reality Bioplastics represent a high growth business opportunity rather than a threat to the plastic recycling industry. One example is PLA, a polyester which can be recycled in a similar way to PET. Separation technology allows high value recycling of both resin types. The establishment of an infrastructure for the recycling of PLA has started recently.
8. Organic recycling of compostable polymers – e.g. in composting plants – adds new efficient recovery options to the world of plastics recycling and has significant advantages where heavy contamination with food waste or soil is unavoidable, e.g. catering products, tableware, mulching film, etc.
9. Energetic recovery is a viable and useful solution until volumes allow the operation of more sophisticated ‘back-to-plastics’ recycling schemes. When renewable raw materials have been used for the production, renewable energy can be recovered.
10. European Bioplastics calls on the traditional plastic and recycling industries, industrial plastic users, NGOs and governmental institutions to develop and establish workable solutions, in legislation as well as in practice, which support the increase of plastics recycling and the use of recyclates – whether from conventional, bio-based and/or biodegradable plastics.

Dans le texte final du Grenelle 2, les mesures censées contraindre les producteurs et les distributeurs à prendre en compte cette priorité "sont étrangement absentes" selon le Cniid.
Et le Cniid de rappeler que Jean Louis Borloo, Ministre de l’écologie, avait déclaré en 2008 que toutes les mesures visant à lutter contre le suremballage seraient prises : la seule petite mesure qui ressort après trois ans de débat est donc l’installation de plateformes de déballage dans les hypermarchés d’ici 2011 (Article 78 ter).
Lot de consolation du Grenelle II pour le Cniid : l’obligation faite aux collectivités de mettre en place un programme local de prévention des déchets d’ici le 1er juillet 2012 (Article 78 – alinéa 33).
