The many uses of cryogenic labels

As proud as we are of all our freezer labels, we know that some of them aren’t sufficient for truly deep levels of cold, like those found in cryogenic medical or scientific laboratories. That’s why we also offer a line of cryogenic labels, both blank and printed to your specifications.

These specialty freezer labels are almost as interesting as what they label, being as far beyond our regular frozen vegetables and ice cream labels as those freezer labels are beyond everyday normal-temperature labels. Cryogenics labels must be extremely durable, with cold-fighting materials including a very high-tack adhesive that the cold won’t touch—one that can, in fact, be applied in very low-level temperatures. Ours at Freezer-Labels.com can easily handle temperatures down to -112° F (the freezing point of dry ice, a.k.a. solid carbon dioxide) without slippage or breaking, and can be applied to almost any standard surface at temperatures down to -20° F.

That’s pretty impressive… but what’s really cool is what they’re used for. Scientific equipment, from freezers to test equipment, are common targets; so are the test tubes that go in those freezers. Often, these contain biological materials, like tissue samples and genetic samples. All biological activity ceases at -136˚ C (-213˚ F), and it slows way down prior to that; some samples can be revived, but others are preserved for further study.

Some hopeful people have even elected to be frozen after death, just in case they can be revived and cured of whatever killed them at some time in the future. The oldest known cryogenically frozen person passed away of cancer that had metastasized to his lungs in 1967. At the time, that wasn’t treatable. While it is now, there’s still no guarantee that he could beat it, and in any case we’re not quite sure how to thaw someone out and bring them back to life quite yet. The “antifreeze” this gentleman was injected with at the time was crude, and many of his cells have no doubt ruptured due to ice crystal formation. That said, he’s remained frozen solid for over 50 years. Maybe someday, nanotechnology may help revive him. One thing we do know is that, having been moved several times during his death, he probably has a nice collection of cryogenic labels by now.

Sperm, eggs, and even embryos are also stored in fertility clinics by people who want to have children and have trouble doing so the normal way. Animal samples of the same materials are also frequently frozen for experimental or reproductive reasons. Such samples also need dependable cryogenic labels. As you can imagine, any slippage or loss of tack of such cryogenic labels would be nothing less than catastrophic. These particular freezer labels also need to be able to adhere to all sorts of materials, including steel, aluminum, cold-resistant plastics, glass, and whatever other materials scientists use or may yet invent for cryogenics use.

Very cold temperatures are also effective for studying some electrical reactions in metals. At extremely low temperatures, some materials become electric superconductors, which are crucial to supercomputers and other electronic devices. Until we can reliably produce room-temperature superconductors, the equipment these scientist use will need dependable cryogenic labels.

The History of Meat Labels

Meat labels as they currently exist don’t have much of a history, really, not even compared to other food labels. After all, commercial freezers and fridges didn’t come onto the scene until about a hundred years ago, so there was no need for freezer labels and refrigerator labels at all. Until then, people reserved most meat products in other ways.

Back in the ancient days, a “meat label” was basically its appearance and smell. You could pretty much tell all you needed to know from that, including the meat’s freshness. Sometimes there were a few color changes involved, but hey, you can’t let that slight green color put you off! All it takes is a few minutes in a fire to sear that away, and it adds to the flavor. Never assume that our ancestors were too proud to eat whatever they found lying around if it didn’t eat them first, or to wait patiently in the bushes for hours, until the lions or wolves finished up. before gathering the leftovers.

In time, we discovered meat preservation techniques like drying, smoking, and salting—coincidentally about the same time our lifespans suddenly increased. Even then, meat labels amounted to, at most, the different colors of bags you put your pemmican, summer sausage, and jerky into. Still, it was better than nothing.

About two hundred years ago, at the beginning of the Industrial Era, true meat labels finally showed up. Manufacturers needed these paper-and-glue inventions to tell people what was (supposedly) in the cans, tines, jars, and wrappers they were selling. Later, as governments caught on, they made the packers put more detailed meat labels on their packages, including all the ingredients, the origins of the meat, and eventually even its nutritional value. After 1913, when people could buy their own refrigerators, label scientists had to wrack their brains to invent new freezer stickers and refrigerator labels that remained stuck to the containers as temperatures plunged and moisture attacked the paper and glue.

The result is the glorious freezer label of today. In addition to classy meat labels, we have all the other necessities as well: popsicle labels, ice cream labels, pizza labels, sausage labels, and even frozen vegetable labels. Modern meat labels include not only the regulatory verbiage inherited from their ancestors, but also items included to make the product appeal to more customers. Aside from instantly recognizable logos, this can include images of varying scrumptiousness, notices that the meat comes from a sustainable population (for seafood labels), warnings about allergies (usually seafood labels again), and whether the meat is Halal (meets Islamic dietary laws) or Kosher (meets Jewish dietary law).

The future looks bright for meat labels, as long as there’s enough room to keep adding new gimmicks and info to draw people in. Got more questions? Ask us at Freezer-Labels.com!
