New PET lidding film eases recycling

Replacing multimaterial, coextruded lids is the aim of a new polyethylene terephthalate (PET) lidding film supplied by Rollprint Packaging Products Inc. (Addison, IL). The processor reckons the new lidding material will be of special attraction to packers using PET, since then the entire package bears a #1 recycling code.Called StreamOne, the polyester lidding, targeted for packaging of medical, pharmaceutical and food applications, comes with benefits beyond aiding downstream recyclability.

Called StreamOne, the polyester lidding, targeted for packaging of medical, pharmaceutical and food applications, comes with benefits beyond aiding downstream recyclability.
 



According to Rollprint, the single-material structure uses as much as 50% less material than some established, comparable lidding films. These structures are often 2.5 mils thick, comprised of a 0.5 mil-thick layer of polyester and a 2-3 mils thick sealant layer.  StreamOne lidding is available in thickness between 1-2 mils, with 1 mil PET and .5 mil of a proprietary polyester peelable sealant.

 “Our customers have been requesting a material that is easier to recycle while still meeting performance requirements. StreamOne lidding does exactly that,” said Dwane Hahn, director of sales and marketing at Rollprint. He adds that the material downgauging potential also leads to savings typically “greater than 15%.”

The new lidding films can be run on horizontal form-fill-seal units and come with a tamper-evident feature; it turns white at the point of contact with the tray when it is removed, without leaving residue on the flange.

As previously reported here, this summer Rollprint opened a new prototype laboratory to help its customers mix and match materials more quickly to rapidly determine which packaging meets the needs for their pharmaceutical and medical disposables. [email protected]
