North America’s Association of Plastic Recyclers (APR) has officially acknowledged the recyclability of KHS’ FreshSafe PET technology according to its Critical Guidance criteria. Using this Plasmax barrier technology, PET containers are coated with a wafer-thin protective layer of chemically pure glass on the inside wall. This coating applied is washed off during the recycling process, producing pure PET. According to the German machinery manufacturer, FreshSafe-PET thus combines product protection with full bottle-to-bottle recycling.
PET bottle without composite materials
The gradual ousting of mixed material PET bottles which are hard to recycle is progressively opening up the market to packaging systems which are easy to recycle. In this context the FreshSafe PET technology reportedly provides a suitable alternative. “We’ve fully satisfied the strict specifications and critical demands of the recognition process,” states Jon Elward, head of Plastic Packaging at KHS USA. “This again proves that this technology is a reference for the recyclability of PET bottles without composite materials.” With it sensitive products such as juice, wine, sauce and liquid food are said to be protected from oxidation and carbonated beverages from carbon dioxide loss. Furthermore, compared to standard composite materials the coating process reportedly provides a better barrier quality and ensures longer product shelf lives, according to the manufacturer.
Design guidelines for recyclability
The Association of Plastic Recyclers is a North American trade association which advocates the recycling of all post-consumer plastic packaging. To this end the association draws up design guidelines and recognizes packaging design innovations that meet its stringent guidance criteria for recyclability, among other things.
