Is there a specific word for this kind of re-sealable plastic seal?

You know those re-sealable plastic bags, where the seal is one plastic strip that you squeeze between two other, parallel plastic strips on the other surface? Like on a Ziploc™ bag, only without the zip?

Is there a common word or phrase used to describe those seals?

Solution 1:

The US Transportation Security Administration (TSA) officially refers to it as a zip-top bag. I have never heard or read this usage elsewhere, and I imagine it was probably constructed to avoid the genericized trademark Ziploc.

In the southeastern US, a resealable plastic bag is usually called a ziplock bag, regardless of whether it has a zipper or not. This is likely true for elsewhere around the US but I can't vouch for that.

Oddly enough, this Web site features macro-images of the bags and several identifying buzzwords, including slider seal, closures, channel, and double zipper seal.

Solution 2:

These are usually called "Press Seal" or "Press-Seal" or "Press-N-Seal" or "Press 'n' Seal" bags. Google "press seal" and look at all the references.

Solution 3:

Resealable seems to be the British English word and the words Robusto said are American English. Supermarkets say resealable (if anything), such as Tesco's bags.
