Number 7 Plastic

Plastic #7 awareness continues to grow. All plastics that do not already fall into resin categories 1-6 must be designated with the “other” marking, which is #7. These categories are required by law in 39 states on certain types of containers. Plastic #7 is often the container of choice for reusable plastic water and baby bottles. In addition, any container made from multi-layered or mixed materials – even when the layers are made from #1-6 materials – must also be marked with the #7 for “multi-layered materials.”
