The European Food Safety Authority (EFSA) has approved three processes for recycling post-consumer polyethylene terephthalate (PET) into food contact materials namely - APPE Supercycle B, LPR and France Plastiques Recyclage (FPR).
The Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF) assessed the 3 recycling processes on several safety parameters.
The panel concluded in its report that all 3 recycling processes ensure that the migration of potential contaminants into food do not exceed 0.1 µg/kg food, based on challenge tests and modeled migration.
APPE Supercycle B: In this process, the inputs are hot caustic washed and dried PET flakes from post-consumer PET containers, not containing more than 5% of PET from non-food consumer applications. EFSA in its reports confirms that the crystallization (step 4) and the decontamination in the SSP reactor (step 5) ensure decontamination efficiency of this process with factors like temperature, pressure and residence time that control the performance.
France Plastiques Recyclage (FPR): The recycling process of FPR is based on Starlinger Recostar PET IV+ technology. According to the panel, drying (step 2), extrusion and pelletising (step 3) and the decontamination in continuous SSP reactor (step 4) are the most important steps in ensuring decontamination efficiency.
The panel concluded that for both APPE Supercycle B and FPR, the recycled PET can be used at up to 100% for manufacturing of materials and articles that come in contact with all foodstuffs and that are intended for long term storage at room temperature, with or without hotfill. The trays made of recycled PET under these 2 processes are not intended to be used in microwaves and ovens.
Lorraine Plast recycling (LPR): The third process approved is LPR and the panel concluded that the recycled PET should be used up to 50% in mixtures with virgin PET when it's used for manufacturing bottles for contact with all foodstuffs and should be used at not more 85% in mixtures with virgin PET in the manufacturing of thermoformed trays and containers, that come in contact with all foodstuffs except packaged water. LPR derived recycled articles can be used for long term storage at room temperature, with or without hotfill.
More on post-consumer PET packaging materials for food products will be discussed at 15th GEPET coming up in Dubrovnik, Croatia on 20-21 May 2014.
Sidel, a leading global provider of PET solutions for liquid packaging, has introduced a new 0.5 litre PET bottle called RightWeight™. The bottle is a lightweight variant that can package still water. Sidel stated that although the bottle weighs less, it does not compromise on product quality and offers better customer experience.
Weighing merely 7.95 grams, the new PET bottle offers top-load performance of 33 kilograms without nitrogen dosing and uses standard 26/22 caps. The new design weighs 34% less than the average commercial bottle. RightWeightTM also promises to save up to EUR 1.75 million of raw-material costs per year.
RightWeight™ bottles are designed in such a way that it doesn't allow 'over squeeze' - an issue often faced by consumers using ultra-light bottles that can lead to content spill.
The new PET bottles scores high on resistance allowing consumers to unscrew the cap and open the bottle while also enabling the bottles to have a longer life in the supply chain. The high resistance means that the bottles will remain intact and retain its original appearance when it appears on the supermarket shelves.
The RightWeight™ bottle is a step in the right direction as it not only reduces plastic but also lowers bottle weight, thus saving energy during production, improving bottle performance across the supply chain while also maintaining product quality, thus guaranteeing a better consumer experience.
RightWeight™ bottles can be used for all Sidel PET packaging solutions which includes the new Sidel Matrix™ system for liquid packaging.
The Sidel team has conducted numerous computer simulations as well as real-world physical tests, so that it can bring to the table the perfect geometrical solution, enabling optimum balance between less weight and strong performance. The team redesigned the standard 26/22 neck finish; thus ensuring an extra 15% savings on weight, at the same time maintaining compatibility of the evolved version with the existing standard 26/22 caps.
More such updates from the PET industry in Greater Europe can be expected at CMT's 15th GEPET on 20-21 May 2014 in Dubrovnik, Croatia.
