Drinks contained in glass bottles contain more microplastic particles than those in plastic bottles, cartons or cans. This was the surprising finding of a study conducted by the Boulogne-sur-Mer unit of the ANSES Laboratory for Food Safety. The scientists hypothesised that these plastic particles could come from the paint used on bottle caps. These findings have highlighted a source of microplastics in drinks that manufacturers can easily address.
I think the plastic particles is a contaminant covering the cap on both sides. In the last section they mentioned the level dropped three times after washing the cap before sealing
