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.

ADHESIVES

FOR PAPERS

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.

FOR FILMS

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.

Tyres

Note: Novatron does not print labels.


Tyre labelling presents a real challenge for pressure sensitive adhesives. The roughness of the substrate and the uneven tyre profile severely limit the contact area between the tyre and label. The adhesive must also withstand migration from chemical components of the rubber as well as the wax or silicone-based chemicals often used as mould-release agents during the tyre manufacturing process. Very aggressive immediate adhesion is required.

Tyres are normally labelled in room temperature by hand or increasingly by automatic dispensing. Subsequent storage conditions can vary from room temperature to warmer or colder conditions in warehouses or outdoors. Accordingly, the adhesive must also maintain its properties in low and high temperatures.

ADHESIVES

RHT

The heavy duty RHT adhesive proves its performance every day on the production lines of nearly every tyre manufacturer. This high-tack, high coat-weight adhesive assures excellent performance to minimise re-labelling due to lost labels and assure reliable tracing and identification.

RH40

RH40 is supplied with cost-efficient label stock alternatives for labelling relatively smooth and even surfaces on particular car and motorcycle tyres.

RD50

RD50 is specially developed for tyre manufacturers’ internal logistics. Labels are dispensed onto the side of the rubber tyre before the vulcanisation process which bonds the tyre components and produces the tread.
