Control Summertime Ooze

The hot, sticky summer weather is upon us, and just like you need to protect your skin from the sun’s rays, you also need to protect your labels from the heat. If you don’t, your labels may be at risk.

As temperature and humidity increase, the adhesives in pressure-sensitive labels can start to soften and flow. Furthermore, a curl in the facestock can occur when the environment moves above 70°F and 50% relative humidity due to the liner absorbing more moisture than the facestock.

You can find a few tips for controlling summertime ooze below:

  1. Unload your labels as soon as they arrive. A trailer sitting in the sun can reach temperatures up to 170°F.
  2. Keep your labels in a climate controlled area, and try to allow rolls to acclimate overnight if possible.
  3. Keep your labels out of sunlight and in the original packaging until you’re ready to use them. This avoids exposing them to humidity fluctuations.
  4. Only handle the labels when needed, and handle with care.

Outlook Group winds your label rolls loosely to avoid any unnecessary pressure on the adhesive, which maintains quality over time.
