Attain up to 100% acceptance into the recycle stream with new foam closure liners

Tri-Seal, a business unit of Tekni-Plex, has launched ProTecSeals, a new line of polypropylene (PP) foam closing liners for a broad type of market applications, enabling up to 100% permission into the material recycling stream at municipal recycling facilities (MRF).

This unique PP foam lining material is designed to work in tandem with PP closures to promote recycled stream reclamation, resulting in a recyclable, mono-material solution, according to DeAnn Umland, vice president, market and strategy development for beauty and home packaging at Tekni-Plex. Making available in both the United States and Europe, this material is ideal for various market field applications, including personal care, beauty, home care, agrochemical, nutraceutical, pharmaceutical, food sauces, and spreadable.

As confirmed by an independent third-party lab, the ProTecSeals liners can be recognized by a correctly calibrated near-infrared system (NIR) at the MRF as PP. This will enable the PP closure and liner to be accurately sorted into the recycling stream.


ProTecSeals, when applied with PP closures, help our customers to reach the EU 2030 target for recyclable plastic packaging without demanding consumers to perform any material separation before recycling. Tri-Seal gives a material lining solution addressing both customers and consumer market sustainability required with this introduction.
