This high performance, 100% polyester lidding solution is an alternative for medical device applications. Called StreamOne lidding, the structure uses as much as 50% less material and helps companies meet recycling waste stream objectives. StreamOne has been engineered to replace traditional mixed-polymer laminates without sacrificing performance when sealing to polyethylene terephthalate (PET) or polyethylene terephthalate glycol (PETG) trays. Because the material is made entirely from polyester, it can be recycled in the "number one" stream, along with the tray. Traditional laminated combinations can only go in the "number seven" or "other" stream.
