Hefty OneZip bags are plastic zip-lock-style freezer bags. When you take one out of the container, you’ll find it closed.
As the default state for a product, it’s hard to picture something more backward. If you are going to use the bag, you need to open it. Why not just provide the bag already open?
A few possible answers:
- Manufacturing the bags already opened might cost more than manufacturing them closed.
- Consumers might perceive a closed bag as more sanitary. However, the bags come flattened and wrapped within a sealed cardboard box, which would seem to minimize the contamination threat.
- The product designers might not have considered the issue, randomly ending up with closed bags.
Whatever the reason, it’s not a big deal, just a small usability puzzle.
[Update, 8/1/2007: The third comment below, by “Anon,” provides what seems like a highly credible answer to this puzzle. In short: (1) manufacturing in the closed position enables a tighter seal, and (2) the FDA requires it for sanitary reasons.]
