Visually, a clear PVC bottle looks exactly like a clear PET water bottle. However, allowing them to mix is like mixing salt into a sugar jar. Failing to control PVC contamination in PET recycling won’t break your washing machines<\/a>, but it will completely ruin the plastic material itself. To understand why we must avoid PVC at all costs, we need to look at what happens when your buyer tries to use the plastic flakes you sell them.<\/p>
