![]() ![]() So it can be a mistake to solely focus on the percentage of rPET the quality is far more important.īecause of this, many bottle manufacturers have given greater attention to preform quality, in accordance with the old axiom “garbage in = garbage out.” Bad preforms become bad bottles thus it’s logical to prevent a quality problem rather than react to one later. This is because not all rPET is created equal – a small percentage of poor quality rPET can have a more significant impact than a higher percentage of good quality. It’s important to point out that the absolute percentage of the rPET being used isn’t directly proportional to the increased risk of defects. This is in large part due to the unpredictable nature of PET performance that results from a wide (and minimally controllable) range of material variability. ![]() The increasing use of rPET introduces distinct production-related difficulties. Successful bottle manufacturers who are using rPET will get the most benefit and value from machine vision solutions when the inspection technology is deployed in the blowmolder rather than in standalone systems. The increased percentage of rPET/PCR in beverage bottles, in combination with lighter weights and faster line speeds, have created an environment wherein the delicate balance between optimum quality and maximum output is more tenuous than ever.įurthermore, ever-stricter regulations continue to demand an unparalleled focus on food and beverage product and packaging quality so as to ensure consumer health and safety. ![]()
