How Do You Ensure Adherence Of Food Labels After Heating, Refrigerating Or Freezing?

Posted on: Jan 12, 2022 | Author: eTraffic

If you have ever tried to apply digital labels on consumer products, you have probably run into some problems like labels curling or not sticking properly onto surfaces. The main cause of these issues are changing temperatures. As temperatures drop in winter, label issues can occur. From adhering to surfaces to wrinkling, puckering and curling, weather conditions have a direct impact on the reliability and performance of a label. Although these issues can be quite frustrating, they are often easy to solve.

How Do You Ensure Adherence Of Food Labels After Heating, Refrigerating Or Freezing?

In most cases, food label issues arise when adhesion is done at the wrong temperature. Cold refrigerators and warehouses with unregulated temperature changes can expose products to varying, uncontrolled environments. Shipping areas also have uncontrolled temperature settings, and depending on the weather conditions, labels may become brittle and firm, which reduces the tack quality. While the loss of adherence may not be noticed immediately, the label may fail and fall off at a later time.

Label failures frequently force manufacturers to reprint and/or reapply labels, both of which result in a waste of money and time. 

Different Environments & Applications

Cold temperatures call for digital labels that are specifically designed for extreme environments. However, there are many sub-categories in the cold-temperature label category. Some labels and adhesives are better suited for frost and moist conditions, while others are better suited for cold and dry conditions. Do you know which food labels to choose for your business’s specific needs?

What’s The Difference Between Cold and Freezing?

  • Cold

For cold and dry conditions, you should go with General Purpose Labels. 

When made with hot melt rubber adhesive, these labels can be applied between 1.7 °C and 49 °C, and can withstand a temperature range of -17.8 °C and 49 °C. If the labels are made with an emulsion acrylic adhesive, they can be applied in temperatures as low as -17.8 °C and can work properly in temperatures between -53.8 °C and 93 °C.

  • Freezing

For freezing and moist conditions, you should go with Freezer Grade Adhesive Labels. 

These labels work well for all temperatures below 0 °C. Products like medicines and ice cream need to be stored in cryogenic or freezer settings to remain viable. Freezer Grade labels can be applied at -26 °C and remain intact between -53.8 °C and 48.9 °C.

Tips To Ensure Adherence Of Food Labels

Have you ever experienced problems with any of the following?

  • Labels falling off
  • Labels curling or peeling
  • Lower tack (label stickiness is not as strong as you would want it)

Here are some helpful tips:

1. Keep Products Clean And Free Of Oil, Dust And Other Residue

Consumer products and labels are often stored in dirty and dusty locations where they can easily collect dirt, dust, oil or debris. These contaminants can negatively impact the label’s adhesion if they get into contact with the application surface.

2. Keep Products Completely Dry

While some labels are designed to stick to wet surfaces, general-purpose labels require dry application. Water can cause labels to peel off of surfaces, making it a hindrance to the proper application of labels. Freezer labels should be used when applying labels in moist conditions.

3. Store Labels At Room Temperature

It is advisable to keep food labels at room temperature up until application. This is because in cold seasons, warehouses can get chilly, causing labels to lose their tack.

4. Label In Batches

If you are planning to label a huge number of products in cold temperatures, it’s highly recommended that you do so in batches. If you take too many labels out at once, they may begin to get cold and this can reduce their effectiveness.

You can use the above tips to reduce the number of times you have to reprint or reapply food labels.
