What Are High Tack Thermal Labels?

EcoEnclose High Tack Thermal Label Rolls were introduced for use on our Padded Mailers, which have an uneven surface and are difficult to adhere to. These shipping labels utilize a hot melt adhesive, which is 100% adhesive (no water), similar in material makeup to a hot glue stick. This makes for a stronger and more permanent seal than can be achieved through acrylic emulsion. Most labels, including UPS and DYMO labels, utilize acrylic emulsion adhesive (which are ~50% adhesive, ~50% water). 

It is important to recognize that these are NOT a more sustainable option than standard labels. They are a solution designed to help companies ensure they can successfully use 100% recycled paper-based packaging that has an uneven or cushioned surface.

These labels utilize a gap or transmissive setting. 

 Compatible printers:

Some thermal printers will have both a Reflective/Mark Setting, and a perforated Gap Setting. The high tack labels utlize a gap sensor.

The best advice for finding a printer is to reach out to the printer manufacturer directly if you have any questions as to the compatibility and what settings the printer offers. If you have already purchased a printer, you may be able to find the information in the instruction manual.

Zebra Label Printers: Zebra Label Printers all have a black mark and gap sensing setting. Some require you to adjust the settings within the software itself. This article provides guidance as to how to find settings and adjust:  https://www.zebra.com/us/en/support-downloads/knowledge-articles/zebra-setup-utilities--configuring-printer-settings.html

  • If the labels don't work on your printer right away, you may have to change the settings, or you may have to calibrate the printer, or input the size of these labels (4x6") as it may differ from what you were previously using. For example, if you have historically been using UPS labels, those are 4 x 6.25”. Our thermal labels are 4 x 6" so you would have to change the setting for the label size. 
  • After changing the settings, unplug your printer for 1-2 minutes, then replug. Then restart your computer to allow the changes to take effect.
  • Clear the history on your computer.

If you are not sure if our labels will work in your printer, you are welcome to place an order to test them. Try the different setting options and if our labels do not work we are happy to process a return for you!
