Design considerations

The challenges of low temperatures and surface condensation can cause application and durability failure modes with your cold storage labels. Regardless if you are applying a general purpose label for cold chain refrigeration or cryogenic labels in a healthcare setting, understanding your unique variable and possible failure mode is critical for finding a viable cold storage labeling solution. Below we outline some considerations that we help you consider when designing your cold storage label solutions.

Cold-induced failure modes

During any storage or transportation of packages and products in the cold chain environment, many variables can influence short and long term performance of your labels including:

  • Initial label application temperature

  • Lack of climate control at extreme cold temperatures

  • Wild temperature fluctuations during storage and/or transport

  • Initial label application temperature

  • Lack of climate control at extreme cold temperatures

  • Wild temperature fluctuations during storage and/or transport

Surface adhesion at sub-zero temperatures

When selecting an adhesive, there are key parameters to take into consideration including the labeling process temperature, the storage conditions immediate post application, and long term storage throughout the product’s life cycle. There several factors that influence the overall performance of an adhesive:

  • Spread out time: required duration for an adhesive to fully cure and is affected by temperature, humidity and the material type.

  • Minimum application temperature (MAT): lowest temperature the adhesive will function upon applicaiton.

  • Service temperature range (STR): temperature range an adhesive retains its functionality post-curing.

  • Peel: the amount of force required to break the bond between an adhesive and the applied surface to determine the strength of the bond.

  • Tack: the rate of adhesive bond formation to the surface under moderate pressure.

  • Sheer: the ability of a material to resist lateral forces that causes it to slide against itself.

  • Glass transition temperature: the temperature at which the adhesive changes from a rigid to a soft pliable state or vice versa.

  • Surface cleanliness: surfaces that contain a high degree of debris or oils may potentially compromise the ability of the adhesive to firmly grip the surface.

Choosing the appropriate face stock

In addition to selecting an appropriate adhesive, the face stock makes up the bulk of a label and is equally important to get right. For example, standard temperature labels made from untreated paper are incapable of withstanding extreme cold environments or high levels of humidity. We have several face stock materials available that is appropriate for most cold temperature labels applications but each have their own benefits and drawbacks:

  • Polyester Labels – Great material for cold storage as it remains flexible in extreme temperatures, great moisture resistance, and is compatible with direct thermal and thermal transfer printers. However, it has poor UV resistance.

  • Polypropylene – it is less resistant at ultra low temperatures, but offers good all-around performance.

  • Coated paper – paper with gloss and semi-gloss coatings are temperature resistant, and do not absorb surface moisture readily.

Frequently asked questions
  1. Why are ultra low temperature labels important?

    • Label durability in extreme cold conditions as cold as -196 °C is mission critical for preservation, identification, and tracking of biologics including vaccines, active pharmaceutical ingredients, blood, stem cells, tissues, etc. At such extreme cold, biological function ceases, effectively making it mandatory to preserve products at these temperatures to keep the products stable. Without proper preservation, identification, and tracking of precious life saving products, many advancements in our modern medicine and health may not be possible.

  2. Are your cold storage labels made to be in alignment with OSHA, ISO, GHS, GMP, FDA, and other regulating bodies labeling requirements?

    • Yes, we work with all of our customers to ensure your labels are in spec with your regulating body requirements.

  3. How do your labels resist freeze thaw cycles?

    • Our adhesive labels are formulated to have a broad service temperature range, allowing for consistent high performance at extreme temperature ranges.

  4. How do your cleanroom standard labels compare to freezer grade and cryogenic cold storage labels?

    • Our general purpose cleanroom labels feature an acrylic adhesive that is graded for down to 0 °C only. Our deep freeze, ultra deep freeze, and cryogenic labels come with a high tack adhesive that remains adhered to the surface down to -196 °C.

  5. What surfaces do your adhesives adhere to?

    • Our adhesives are graded for use on a wide variety of surfaces like plastic polyolefins, glass, foil, and metal. If you believe you have an unusual or difficult surface, contact our sales teams and we will help you choose the right for your application.

  6. What are the differences between cold chain, deep freeze, ultra deep freeze, and cryogenic temperature?

    • Cold chain is standard refrigeration condition from 2 °C - 8 °C. Vaccines are commonly stored and transported at the level. Deep freeze is 0 °C to -40 °C, Ultra deep freeze is -40 °C to -80 °C and often referred to as CO2 cryogenic. True cryogenics begin at -196 °C with liquid nitrogen cooling.

  7. Why are my labels not adhering properly with my package’s storage environment?

    • Low temperatures cause the adhesive to stiffen and freeze, making them brittle.

    • Applying labels to frozen containers extends spread out time for the adhesive and prevents labels from bending as they wrap around containers.

    • In colder environments, excess moisture tends to collect more surfaces, creating additional condensation which interferes with an adhesive’s tackiness.

  8. Why do labels fail on cold storage products during transportation?

    • Adhesives and labels can become stiff in freezers due a breach in them reaching their glass transition state, causing them to lose their adhesive properties and lift off the package or product.

    • Label separation from the package is further exacerbated in freeze thaw cycles where the wide fluctuations in temperature causes significant expansion and contractions of packages.

  9. Why is knowing spread out time important?

    • This is the time required for creating the permanent bond between the adhesive and substrate. When a product or package goes into the freezer before the label has completely spreaded out, the label will be subject to critical failure and in general will perform worse than expected.

  10. Why do you need to know what your MAT and STR requirements are for a label?

    • Being unaware of the differences (see cold storage considerations) may lead to unintentional misuse of the labels. It is important to understand the two terms to maximize performance and longevity of your label.

  11. What applications are cold storage labels useful in?

    • Freezer labels, medical labeling, pharmaceutical labels, laboratory and research labels, cryo storage, vaccine labels, syringe labels, 5 S labeling, and much more!
