Low-temperature storage down to -80C with multiple freeze-thaw cycles
RP80 LT is designed to perform in storage conditions down to -80 C. The RP80 LT adhesive also withstands multiple thawing and freezing cycles as samples are thawed at room temperature or in warm or iced water, and later returned to the freezer.
With good mandrel hold, this adhesive is recommended for identification labelling on laboratory vials, ampoulesand test tubes, as well as plates, slides, steel cabinetsand storage boxes. RP80 LT retains its adhesion for extended periods, on surfaces including glass, steel, cardboard and PP.
Cryopreservation labelling down to -196 C
Cryogenic storage stops time for countless tissues, cell types and subcellular materials. But if these biological samples can’t be identified, they are lost forever.
UPM Raflatac label materials based on the RP Cryo adhesive withstand steam autoclave sterilization and cryopreservation conditions down to -196 C, in both vapour phase and liquid nitrogen. This adhesive is extremely resistant to thermal shock, and provides a strong and enduring bond to polypropylene (PP) cryogenic vials, tubes and storage boxes.
RP Cryo also withstands multiple thawing and freezing cycles, further ensuring that valuable biological samples are identifiable for the duration of their cryogenically extended lifetimes.
Migration-safe labelling for liquid drugs in plastic containers
RP31 Purus is a ‘migration safe’ adhesive with low leachable characteristics. Leachables are compounds that leach from packaging because of direct contact with the drug product under normal storage conditions and could potentially be dosed to a patient. Migration is a concern particularly for drugs in liquid or gaseous form, stored in containers made from plastic materials.
RP31 Purus performs well on small diameters and curved surfaces, and on a variety of labelling substrates including PP, PE and low-density polyethylene (LDPE). LDPE is widely used for squeezable nose or eye-drop containers, where migration safety is critical.
The FDA has assigned Drug Master file (DMF) number 25392, type III for RP31 Purus.
Primary blood bag labelling
Regulatory requirements and the extreme conditions associated with blood storage and processing place stringent demands on labels for blood bags. RP32 PB has been developed and tested according to guidance from the ISO 3826 standard. It withstands temperatures of +121 C during steam sterilization, down to long-term storage conditions of -80 C. It also tolerates freezing in ethanol at -50 C.
RP32 PB has low-leachable characteristics on blood bags and is compatible with various plasticizers used in PVC blood bag manufacturing, including the most common, DEHP.
RP32 PB is supplied with a choice of non-PVC label faces according to market preferences.
RP31, RP31L, RC3P
Labelling small diameters
Small-diameter containers – such as syringes, ampoules, cartridges, pens, vials and test tubes – place special demands on label construction. UPM Raflatac’s research indicates that a diameter of 15 mm is the threshold at which the choice of label material becomes critical. Thin and flexible label faces are supplied with the following adhesives for optimal performance.
RP31 is formulated for labelling curved surfaces and small-diameter packaging. It offers a reliable solution for a wide variety of applications requiring excellent mandrel hold. RP31 bonds strongly to glass, HDPE and PP ubstrates.
RP31L is essential in applications where product identification must be secured by reducing the risk of missing labels to zero. Supplied with clear films, RP31L offers luminescent functionality for missing label detection on label dispensing lines and is a convenient and consistent solution compared to luminescent varnishing on-press.
RC3P is a UV-acrylic adhesive with excellent clarity for labelling on glass and is especially beneficial for visual checks of liquid container contents. Good water, heat and chemical resistance make RC3P suitable for a wide range of applications as well as end-uses requiring resistance to steam autoclave sterilization.
Genuinely self-adhesive on surgical sterilization wraps and bags
ΤReusable surgical instruments leaving hospital operating theatres are cleaned, washed, packed on trays and wrapped in non-woven or crepe wrapping material, prior to sterilization by steam autoclave. Allpacks are individually labelled for identification and traceability.
RP3H retains excellent adhesion in the steam, pressure, and heat of the autoclave process, which is typically at 134 C for up to 18 minutes. This adhesive also accommodates swelling and shrinkage of various wrapping materials during and after processing.
Uniquely, RP3H labels are genuinely self-adhesive because no additional sealing tape is required to secure label adhesion. Light application by hand is both convenient and cost- efficient.

Labelling on durable goods emphasizes particular conditions in which the label must perform and the life-expectancy of the label.
Requirements for resistance to exposures including heat, chemicals and solvents, moisture and water, mechanical strain, outdoor weathering and UV light vary widely. But in all cases, information such as model identification, serial numbers and warnings needs to last the lifetime of the labelled product.
Durable labelling is therefore an end-use category where a cross-linked adhesive – for example UV acrylic or catalyst-activated – will likely be required.
This is regardless of how well the labelled surface favours bonding in terms of surface energy, though naturally the adhesive will be adapted to the polarity of that substrate.
Electronic and electrical devices and their components and casings are typical examples where select UPM Raflatac adhesives demonstrate excellent durable labelling capabilities – computers, white goods, sports and fitness equipment, power tools, industrial machinery and automotive parts.
Moreover, our advanced non-solvent solutions enable label printers and end-users to move their durables business forward sustainably – and achieve market differentiation through environmental responsibility.
UV-ACRYLICS FOR ENDURING RESISTANCE TO HEAT, CHEMICALS, WATER AND UV LIGHT
Our UV-acrylic adhesives have high internal strength(cohesion) which makes their properties of adhesion resistant to long-term exposure to high temperatures, water, chemicals and UV. This high cohesion is achieved by chemically locking together the molecules in the adhesive with ‘cross-links’, which form during our label stock manufacture when the coated adhesive is exposed to ultraviolet light.
RC15 is specially designed to provide outstanding adhesion on polar surfaces like glass, steel or ABS.
RC18 is designed for films in combination with paper or film liners, in end-uses requiring very good adhesion on polar and non-polar surfaces.
RC20 has a high coat weight for rough and demanding substrates, and has very good adhesion on polar and nonpolar surfaces.
CATALYST ACTIVATED FOR EXTREME RESILIENCE
UPM Raflatac has introduced a new, catalyst activated adhesive (CAA) technology. As with our UV-acrylics, the adhesive undergoes a cross-linking reaction on our coating lines to increase the adhesive’s internal strength. With the ‘RX’ adhesives we have achieved a very high density of cross-links, for extreme cohesion and resilience. The first of this new series is RX15.
RX15 offers label converters and end-users a unique opportunity to combine top-level technical performance with an excellent sustainability profile. RX15 has extremely high adhesion on polar surfaces, good heat resistance and excellent resistance to UV-radiation and chemicals. Applications range from dumper trucks to solar panels and wind turbines.
For some applications, a film label face such as PET combined with a selected waterborne acrylic adhesive provide sufficient resilience for shorter-term exposure to water, UV and some chemicals. RP37S serves this general purpose need for labelling on both polar and non-polar surfaces.
Reinforced films and tags
High tack and cohesion make this adhesive particularly suitable for adhesive-on-adhesive applications, where the label or tag material loops back to itself. RP33 is designed for use with tear and cut-resistant reinforced films such as Tyvek and PE White Strong. A typical application is cable-labelling.
UPM Raflatac supplies clear PP and PET overlaminates for lamination over durable labels, for applications where the printed image is at risk.RP35 provides good clarity and UV stability, in applications requiring overlaminated print protection from dirt, water splashes and abrasion.
RC35 is designed for overlaminating film label faces. This adhesive has excellent long-term resistance to heat, chemicals, water and UV.
RC35 also has excellent wet-out behaviour, particularly when supplied on a film liner which produces a smoother surface on the adhesive. This makes it suitable for overlaminating even on dark-coloured label faces where it is difficult to achieve good transparency.
