One possible cause for a rapid shift towards the new labels, at least among producers of children's garments, is the onset of a federal ban on three phthalates and interim restrictions on three others. Given that the "ECO" labels are advertised as PVC-free, and PVC frequently contains phthalates as a softener, it seems entirely plausible that Avery-Dennison, as well as their clients, are moving rapidly to ensure they stay in compliance with the evolving regulations in this area, and that the tags that have been used by Carter's and other brands up to this point have contained them. Phthalates are the suspected chemical of concern logged in ZRecs Guide listings Carter's infant apparel on September 28, 2008. [Link]
