Today, we have a bonus episode for you. And it’s all about Tyvek. Yes, that wondrous paper-like, fabric-like material, that is actually neither paper nor fabric, that our industry uses to make race bibs. Well, that wondrous material is now in a bit of a supply freeze. That’s right - the owners and exclusive manufacturers of Tyvek, DuPont, have informed printers that no more printing-grade Tyvek shall be made available until the end of the year, in an effort to divert production to medical-grade Tyvek, used in PPE and medical supplies, which, not surprisingly, is in high demand lately. So what is to become of Tyvek race bibs? I sat down with Marathon Printing President and third-generation bib printing specialist, Ryan Zirk, to find out.  In this episode: Tyvek's special properties making it ideal for race bibsTyvek's (many) other industrial uses: PPE, packaging, weather barriersPrinting on Tyvek bibs: from bulk Tyvek sheets to finished bibsPrinting Tyvek at home: can it be done?Recycling Tyvek bibs: where and how you can recycle your Tyvek bibsDuPont's announcement of halting production of printer-grade TyvekAlternatives to Tyvek for printing bibs, if printer-grade Tyvek inventories are exhausted Thanks to GiveSignup|RunSignup for supporting quality content for race directors by sponsoring this episode.
