Waste & Resources Action Programme (WRAP) has carried out a research to enhance recycled PET (rPET) quality for use in food packaging, in response to engagement with users of rPET in the UK.
The users, according to WRAP, said their ability to increase rPET in new drinks bottles and food packaging was being affected by the quality of the material itself.
Conducted with plastics reprocessors, converters and end-users such as retailers and brand owners that use rPET in packaging applications, the project was aimed at identifying what the material’s quality issues were and to investigate the root causes and develop some solutions.
WRAP’s report makes recommendations to improve food grade rPET quality to further stimulate demand for it, which can help boost the recycling infrastructure in the country for PET reprocessing.
The factors affecting rPET quality include packaging design, quality level of recovered bottle bales from materials recovery facilities and reprocessing methods.
