Rigid Packaging

Rigid Packaging Thermoformed trays from Bio-Flex F 6611 Kids in Naples enjoy their lunch from new trays Urban Schools aim for Environmental Revolution Nothing seemed to be special about the food trays from which pupils at several Naples schools consumed their meals: rigid, angular and white. But looks can be deceiving: They are the pioneer of what could become an environmental revolution in schools across Italy. The use of compostable catering is the first initiative of the City of Naples for an environmentally friendly realignment of the city’s goals, encouraged by the Green Public Procurement (GPP) regulation. On this background, the catering company Sagifi, historical company which has been operating for more than 25 years (1984) in the catering sector, established the Project AORNCOMPOST in the summer of 2012 entrusting Plastisud with the development of a compostable tray for use in school cafeteria’s in the City of Naples. The requirements and expectations have been challenging: a tray that is certified for food contact, applicable for hot food filling, stackable and sealable with a compostable film as well as the tray being compostable itself - all in one. Plastisud, in collaboration with FKuR, developed an innovative tray for catering services. In this context both parties contributed their knowhow to meet the challenges. On the one side the processing knowledge in extrusion and thermoforming, on the other the in-depth material knowledge. “By using FKuR’s bioplastics we were able to reach a very satisfactory solution”, stated Stefano Bartoli, Production Manager at Plastisud. After a year of testing, experimentation and small steps forward, the synergy between Plastisud and FKuR led to the realization of the Aorncompost tray. Featured with a heat resistance of more than 90 °C the tray made from Bio-Flex ® F 6611 (a blend of PLA and co-polyester) is suitable for hot food filling. In addition, the tray is not only biodegradable but also compostable according EN13432 and has been certified by CIC Italian Composters Consortium. In September 2013, the tray achieved the CIC certification and started to be used successfully in Naples schools. Along with any uneaten food, the plates made from Bio- Flex F 6611 can be disposed and turned into a valuable product prized by gardeners and farmers: compost. Bio-Flex F 6611 is certified GMO-free and in addition to its biodegradability/compostability it is predominantly composed of renewable resource raw materials. The Bio-Flex grade is ideally used for thermoforming. It is pleasant to the touch and has a pearlescent gloss. Plastisud is an Italian company, established in the greenery Abruzzo region of Italy. For over 25 years the company has been a specialist in the production of disposable products for food packaging and catering services. This success story represents an example of a small family-owned Italian company dedicated to innovation and passion in processing plastics. “It is important for us to emphasize our ecological awareness and send a signal. By using bioplastics we can fulfil our wish to have an overall environmentally friendly solution“, confirmed Bartoli. MT 16 bioplastics MAGAZINE [02/14] Vol. 9

Rigid Packaging Compostable meat packaging After 6 years of research Bio4Pack (Rheine, Germany) proudly presents its fully compostable and fully renewable meat packaging. Bio4Pack, well known for its renewable and compostable vegetable and fruit packaging and shopping bags, has been exploring ways to introduce compostable packaging to other markets. Together with strategic partners such as NatureWorks, Taghleef and Bio4life they managed to produce a biobased compostable meat packaging that’s just as good as traditional packaging for meat products. But not only as good as traditional packaging, but in some ways even better than traditional packaging. The meat packaging consists of a thermoformed tray made of a 3-layer laminate (20µm PLA / 2µm proprietary barrier material / 2µm PLA) and lidding film of the same barrier construction. Important conditions during the development of the compostable meat packaging were among other things that the trays could be handled as easy as traditional trays on packaging machines and the pricing would be on the same level as traditional packaging. On top of that, perhaps most important, the packed meat had to look as good as meat packed in traditional packaging after a few days. There had to be no obstacle for professional packers other than getting used to the fact that meat can be packed in biobased compostable packaging. Bio4Pack managed to meet all mentioned requirements. In fact in some situations the PLA trays performed even better than traditional PET trays. Tests performed by KBBL (a well known accredited lab in Wijhe, The Netherlands) showed that meat, for example, looked better after a few days when it is packed in a Bio4Pack packaging. “A reason is the very good barrier against CO 2 and oxygen,” as Patrick Gerritsen, founder and owner of Bio4Pack points out. “The permeability for water vapour however, is still good.” All together this enhances the shelf life and the quality of the packed meat. Bio4Pack’s new meat packaging is fully compostable and entirely made from renewable resources. That means that not only the tray is compostable, but also the label, the top film and the absorption pad in the tray. They trays are available in standard British sizes, but can also be ordered in other sizes. bioplastics MAGAZINE [02/14] Vol. 9 17
