So, does one year shelf life for PS label materials make any sense at all based on the evidence. Nope. Will this evidence and the informed opinions of technical folks involved in the industry make any dent in this beloved one/two year time frame? Nope. Is a shelf life date even necessary for most modern label stock, given reasonable inventory control, production cycles, and FIFO? Nope. So please forgive me if you hear a sigh, a cleansing breath, when you call me with your underwear on fire about 13 month old label stock, 13 months from some magical, arbitrary, ephemeral start date. I’ll probably calmly ask you what substrates your labels are being used on, send you that letter I received from our vendor, bust our production’s hind ends to get you some ‘fresh’ label stock, and maybe even attach this blog post to my delivery confirmation email. Given regulatory paranoia, I do not see any light at the end of this tunnel however, so we need to be content to wallow in and perhaps even enjoy non-value added time sucking activity. On the label shelf life issue, the mouse traps are carefully set as the elephants are stampeding through the front door.
