Yes, there are many waterproof synthetic papers out there. The vast majority of these are non recyclable and the other small percentage that claims to be recyclable are classified as Category 3 “PVC or Vinyl” and Category 7 “Other”.** Here is a link for a Greenpeace paper on PVC production that talks about this in more detail.
**Category 3 & 7 require special handling and stripping before they can be recycled.
What makes our synthetic paper so different? Our category 5 Synthetic Paper goes straight into the recycling bin with no extra need for special processing, handling, chemicals or stripping.
