31JulPREVIEW: One of the problems that limits the amount of recycled PET (rPET) used in rigid packaging applications is the degree of yellowness that it can cause. The more rPET that is added to virgin PET during bottle manufacture, the more yellow the resulting bottle tends to become. The source of the rPET used has
31JulPREVIEW: One of the primary issues that recyclers face today is the challenge to produce high-quality recycled polyethylene terephthalate (rPET) with low b* (yellow) values. This study wanted to example the effect that repeated melting of PET resins has on color. The trend seen shows (with some sample variability) that the yellowness, measured by b*, increases with
31JulPREVIEW Slow speed-to-market, high tooling costs due to constant mold changes, poor production performance, customer dissatisfaction with functionality and shelf life, enabling creative design intent to translate to the final package. Package performance needs to continue to evolve. With equipment pushing productivity boundaries, new filling technologies and changes in the way goods are distributed, are you taking
