Recycling plastic bottles is vital for environmental protection, but it can affect their oxygen barrier properties, making them less suitable for oxygen-sensitive products. Our case study on PET bottles with varying amounts of recycled material found that increasing the recycled content from 25% to 50% only slightly reduced their oxygen barrier. This suggests that using more recycled material does not significantly compromise the bottles' performance. The Problem The growing trend of recycling waste plastic bottles requires an understanding of how reclaimed materials affect a product's performance. For PET bottles, a crucial metric is their ability to act as an oxygen barrier. High oxygen permeability can compromise the quality of packaged goods, limiting the use of recycled materials in food and beverage containers. This study aims to quantify that effect by testing bottles with varying percentages of recycled content. The Test Two types of PET bottle samples were tested...
