Cleansing efficiency of post-consumer PET is, beside others, the most important aspect to secure food safety for rPET in packaging for direct food contact. Food safety is guaranteed mainly by operating the appropriate equipment with proven cleansing efficiency, continuous process data, rPET quality control, and protocol archiving for traceability. Frequent gas chromatograph tests with rPET deliver even better VOC results than virgin resin.
To prove decontamination efficiency for national authorities and brand-owners, Starlinger recycling technology has performed several challenge tests.
 
Recyclers are obliged to strictly comply with the prescribed process parameters and to monitor them – a task which is ensured by the automatic process monitoring system offered by Starlinger.
 
'''Various proofs for food contact safety''' such as the FDA Letter of Non-Objection, Austrian and French approbations, conformity to EFSA, ILSI and German BfR requirements have been achieved. In addition, brand owner approvals underline the superior quality of rPET produced on Starlinger recycling lines recoSTAR PET iV+.
 
'''Safety first for the whole value chain'''
The various stakeholders in a recycling project have different expectations:


The results demonstrated that the system has excellent cleansing efficiency. This fact shows that it is possible to use up to 100 % rPET produced on Starlinger recycling machinery for packaging with direct food contact.
* The authorities have to make sure that laws for food-safety are observed.
* The recyclers need efficient and flexible recycling equipment to ensure competitiveness in a volatile industry. Process stability and automatisation guarantee the production of food-contact safe pellets.
* The preform producers demand resin-like quality in terms of viscosity (IV), flow characteristics and processability.
* Bottlers and brand-owners require high rPET content without jeopardizing the visual appearance.
* And finally, all stakeholders including the consumers need to be absolutely certain that the packaging is safe.


Various proofs for food contact safety such as the US (FDA Letter of Non-Objection), Canadian, Austrian and French as well as ILSI and German BfR approvals have been achieved. In addition, the conformity to EFSA and brand owner approvals underlines the superior quality of rPET produced on Starlinger recycling lines.
