Safety, information, traceability, and the prevention of stock losses – the label transforms industrial chemicals stored in Intermediate Bulk Containers (IBCs), steel and HDPE drums and many other container types into usable goods.

Adhesive selection needs to take into account the surface energy of polar surfaces like metals, paints and lacquers, and more challenging non-polar surfaces such as HDPE plastic. Other parameters include the smoothness or roughness of the labelled surface, the condition of the surface at the time of label application, and possible requirements for momentary repositionability.

After labelling, the adhesive needs to tolerate the conditions in which containers are stored and transported as well as any contact with the container contents. UPM Raflatac draws on decades of technical expertise to formulate adhesives for these highly demanding applications, for the lifetime of the labelled goods.

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.

The beverage industry is renowned for exceptional branding and marketing to catch the eye of the consumer and stimulate point-of-sale decision-making. Labels need to maintain a high-quality appearance and flawless performance in variable conditions during the lifecycle of the bottle.

During the bottling process, the adhesive must provide good tack in manual and automatic applications, possibly at low temperatures and in humid conditions. Areas where there is inconsistent contact between the label and bottle might not be visible immediately, but can lead to the development of bubbles or creases.

With clear filmic materials supporting a pristine ‘no-label look’ it’s vital that the adhesive remains clear during the life of the bottle. Excellent surface contact is required for good adhesive wet-out to prevent haziness. If exposure to moisture or water will be concerns after labelling, the adhesive needs to be resistant to water-whitening.

ADHESIVES

RP37

Multipurpose and multi-tasking

This multipurpose adhesive is for film label faces on. paper liners, and provides good adhesion on glass and even plastics. RP37 has good resistance to water and UV to retain reliable properties of adhesion for the entire label lifecycle. An optimal balance of high adhesion and high cohesion provides clean and stable performance in high-speed conversion and label dispensing, even in potentially moist and chilled conditions.

RP74

Quality, ultra-clear ‘no-label look’

RP74 is designed for a quality no-label look in combination with clear label faces and PET film liners,which encourage a smooth and clear adhesive wet-out. Long-lasting clarity is assured by excellent resistance to water-whitening once labelled. Good cohesion provides clean and stable performance in high-speed conversion and label dispensing.

RP76E

High-speed, high-productivity labelling

Specially designed for beverage and spirits labelling, RP76E provides good adhesion to smooth polar surfaces like glass bottles and metal and lacquered metal cans. It is supplied with clear film label faces on filmic liners. Excellent UV-stability plus resistance to water-whitening once labelled assures long-lasting clarity.

RP76E’s extra-high cohesion and the strength of a PET liner enable reliable high speeds and high productivity in label conversion and dispensing.

RC7B

Wet labelling clarity plus pasteurization

This UV-acrylic adhesive is designed for bottle labelling applications where excellent water and moisture resistance are required – providing good adhesion and retaining its clarity even on wet bottles. RC7B’s excellent temperature and water-whitening resistance also make ita good match for applications where bottles are labelled prior to pasteurization.

RC7W

Clean wash-off for recovering food-grade PET

RC7W is specially designed for wash-off film labels on PET beverage bottles destined for recycling. During the wash-off process in hot caustic, gravity separates label materials with RC7W from ground-up PET bottles. This produces pure, food-grade polyester suitable for re-use as bottles. RC7W has excellent performance in highspeed dispensing and is resistant to water-whitening once labelled.

While electronic communication has reduced the overall size of the market for postal stamps, demand is growing for special editions for philatelic interests. Requirements are also growing for embedded security features which authenticate high-value stamps.

UPM Raflatac offers considerable resources in materials expertise and product innovation, in addition to security solutions to safeguard postal operators’ revenues. All our label faces, in rolls and sheets, are available both gummed and self-adhesive. We’re also able to develop truly unique products – such as the world’s first flavoured, gummed adhesive postage stamp.

Gummed

This non-self-adhesive, water-activated synthetic gum is designed for moistenable paper coating applications, for example to adhere a postage stamp to letters and other mailed items. This is the traditional ‘lick-and-stick’ stamp adhesive.

Permanent Stamp

More and more countries are moving to permanent stamp adhesives to help prevent stamp re-use. Perm Stamp meets this need when removability by water soaking is not required. Perm Stamp is designed for sheet and booklet conversion, with bleed-resistant properties to avoid sticky edges.

Permanent Stamp Soak-Off

Stamp collectors have traditionally removed gummed stamps from envelopes by soaking, but not all self-adhesive stamps make this easy. If the stamp has to be soaked too long, the paper becomes fragile, and the stamp is easily torn. Permanent Stamp Soak-off is permanent as the name suggests, but removes easily by soaking in water. It leaves stamps intact and free from residue, protecting the value of the stamp for years to come for philatelists, and driving continued enthusiasm for the stamps business. Perm Stamp Soak-Off is designed for sheet and booklet conversion, with bleed-resistant properties to avoid sticky edges.
