You might be wondering what distinguishes freezer-grade labels from everyday all-temperature or "all-temp" labels. Well, the differences can be subtle, but they definitely exist.
First of all, the all-temp labels aren't, really. They can handle an impressive temperature range, from below freezing on the low end to approaching the boiling point of water on the upper, which makes them ideal for outdoor extremes to be encountered in just about any temperate or tropical zone. But they don't always do well in serious cold. We humans can create temperatures far lower than anything Mother Nature can, and "all-temp" though they may be, these labels just can't handle truly low temperatures—say, below about 20° Fahrenheit. Furthermore, they're usually not formulated to withstand moisture and frost, which can become a problem in very cold environments.
All-temp labels may work fine for cool environments, like those in a store's drinks or ice cream cooler. But many all-temp adhesives lose adherence when it gets colder, meaning the labels can just fall off at any time. The substrate and inks might become dry, brittle, and flaky even if the adhesive doesn't fail. They can't handle the real chill. All-temp labels also tend to be made of emulsion acrylics—though as you can see on our Materials page, some emulsion acrylic adhesives can handle temperatures down to as low as -65° F.
True freezer-grade labels are made to survive very cold temperatures all the way around. Not only can they be applied to surfaces that are already frozen, most are guaranteed down to at least -65° F, while special cryogenics labels can deal with the incredible cold of liquid nitrogen, which boils at -321° F. (Not freezes: boils.) Now that's heavy duty! Inks, substrates, and adhesives alike all have to survive long-term in extreme cold—often for years. The substrate can't crinkle, wrinkle or flake, the ink can't freeze-dry and fall off, and the adhesive can't deaden. Ever. Some freezer labels can even handle moisture and frost build-up without peeling or degrading, depending on the materials, though some can't. Most true freezer-grade adhesives are made of hot-melt rubber, which is designed to be applied in frozen environments and stays nicely sticky in very cold temperatures that defeat many emulsion acrylics.
