I just bought a box of 100 sandwich bags and on the box there is an (U) symbol. This is neither unique nor uncommon. Why do marks of hechsher appear on non-food products? Is there anyone in the world looking for such a hechsher or making plasticware decisions based on it?

I've seen hechsherim on soaps. Hacham Ovadia (Yabia Omer O"C 9:100) ridicules this practice. – Baal Shemot Tovot Apr 16 '12 at 16:23

Food-contact.

From the Star-K:

"Quite frankly, we were astonished to learn of the rather extensive use of stearates and other tallow based chemicals in the production of plastic food-contact materials. These chemicals may be added to plastics in various formulations at concentrations as high as two percent with the intent and knowledge that they will migrate to the surface, thereby interacting with the foods they contact. Due to this migration and interaction the FDA requires that all additives used in plastic food-contact materials be of an acceptable food grade quality."

If it is an FDA requirement, then wouldn't all sandwich bags be kosher? (Or do I misunderstand your answer?) If all sandwich bags are kosher, then aren't we still left with the question of why it has a kosher symbol? – Brandon Jul 27 '11 at 16:45

No, quite the opposite. The FDA requires that all additives be food-grade. Halachah requires that all food be Kosher. Hence the need for a Hechsher. – Seth J Jul 27 '11 at 18:16

A-ha. That's clear now (and in retrospect should have been clear before). Thanks! – Brandon Jul 27 '11 at 18:59

From the N.Y. Times:

Only about 15 percent of people who buy kosher do it for religious reasons, according to Mintel, a research group that last year produced a report on the kosher food explosion. The top reasons cited for buying kosher? Quality, followed by general healthfulness.

(I would assume it's so one can be assured no non-kosher residue is on the surface of the bag. But I'm posting this answer mostly for the following.) As to "Is there anyone in the world looking for such a hechsher or making plasticware decisions based on it", well, doubtless. Even if all rabanim who know what they're talking about will tell you it's not necessary (and I don't know that that's the case here), surely someone will look for it.
