Security & Brand Protection
Note: Novatron does not print labels.
Manufacturers and agencies the world over use security label and packaging solutions to protect items from counterfeiting, tampering and diversion. Self-adhesive labels provide an efficient means of identification, authentication, verification of integrity, and monitoring through the supply chain. They protect consumer safety, brand value, and commercial or governmental revenues.
Anti-counterfeiting labels incorporate specific properties or combinations of features into the face material as a means of authentication. These labels are difficult to reproduce, and depending on the level of security used, their authenticity can be checked by brand owners, government agencies or consumers. UPM Raflatac works with customers to build effective custom solutions and provides a taxi-coating service where customers send security face materials for adhesive-coating and lamination.
Tamper-evident or tamper verification labels are based on destructible papers and films that change appearance or are destroyed when an attempt is made to remove them, break the seals they create, or transfer them onto other products. VOID labels are visibly damaged upon removal and additionally leave a text or pattern adhered to the labelled surface which is extremely difficult to remove undetected.
Very often it is the selection of either a paper-based or filmic label face that is the starting point for adhesive selection in security labelling. This selection is based on cost-efficiency and the requirements of the final application. The choice of adhesive is determined by application-specific criteria such as the smoothness or roughness of the substrate, challenging small diameters, the required strength of final adhesion, and resistance to heat, chemicals, and water from the immediate environment or through attempts to remove the label.
RP36 is often combined with thin and flexible paper label faces due to its high cohesion, which supports reliable labelling around package edges or on small diameters.
RP37S provides good initial tack and long-term adhesion on polar and non-polar surfaces and performs well in a broad range of security applications such as consumer product labelling and internal logistics. This clear adhesive has good resistance to water, chemicals, oils and UV-light, and excellent UV-stability once labelled.
RP77 is a versatile adhesive for white films and is typically combined with destructible label faces. This high-tack adhesive provides strong final adhesion on rough and textured polar and non-polar surfaces including PE and PP.
FOR HIGH PERFORMANCE
RC18 provides very strong adhesion to polar and non-polar surfaces in long-term applications and demanding conditions. Excellent resistance to water, chemicals and high temperatures also make RC18 very difficult to soak off, chemically remove or lift by applying heat.
RC20 provides very strong, long-lasting adhesion and excellent temperature and chemical resistance like RC18. In particular, RC20 offers high performance on polar and non-polar substrates which are rough, grained or textured.

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.
