Labels for freezing

Labels for frozen products for deep freezing. They are most often used in the food industry with products stored at low temperatures (often below ZERO degrees Celsius). Due to the specificity of the material being labeled, labels for freezing most often have a super durable (super strong) adhesive with significantly increased adhesion as well as an adhesive for frosted surfaces. Such labels are applied to so-called special materials, flexible packaging used at low temperatures and high humidity. Due to the nature of the packaging of medicines (pharmaceuticals) and life-saving agents, special types of labels with the possibility of freezing to low temperatures are also used for their labeling. Thermal TOP labels and thermal transfer labels, whose paper is more resistant to moisture, are often chosen for freezing. Due to their properties, thermal transfer labels (pharmalite, pharmamatt, pharmagloss) are a slightly better solution. Manufacturers of food products often emphasize their uniqueness by embellishing their labels using cold stamping cold foiling.

If we say “adhesive for deep freezing”, it means an adhesive with which labels can be applied at a temperature of up to -20C and withstands up to -40C. So the application temperature is crucial here. Ordinary rubber adhesives (RH9X, RH01, FH21, S2045n) should also hold up well at -40C, but they cannot be applied at such a low temperature (0C for RH9X and -5*C for RH01). For frosted surfaces, these adhesives are already a higher shelf, also in terms of price e.g. RH03 and C2075n. Of course, everything depends on how much frost is on the labeled surface. If there is too much of it, then we try to stick the label to the ice rather than the packaging - in this case even these adhesives will not work.
