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.

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.

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.

Retail labels are applied to goods in stores, from books and home d cor items to shoes and mattresses. They serve a range of purposes: promotional and decorative use, in-store pricing, weigh-scale labelling, size-marking and other informational needs.

Typically, general purpose adhesives are used. In cases, adhesives are dedicated to substrates such as textiles, or they have finely tuned properties for a particular application. Food labelling has a specific range of needs and regulatory requirements and is covered in its own chapter in this book.

For logistics and transport end-uses, self-adhesive labels are typically variable information printing (VIP) products which route, track and trace objects throughout the supply chain, support inventory management, and streamline operations. They often experience significant wear-and tear during their relatively short lifespans, and may require good low-temperature performance on various plastic and cardboard substrates.

ADHESIVES

RP51

Multipurpose performance

This multipurpose, strong permanent adhesive is suited to a wide range of retail and logistics applications. RP51 adheres well to packaging films, card and corrugated boards, and after labelling retains good adhesion even in chilled temperatures of 0 to 5 C.

RHR5

Convenient weigh-pricing on PE bags

The specially adapted RHR5 hot-melt adhesive has balanced performance for convenient tack at room-temperature on PE weigh-price bags, plus good resistance to bleeding for clean, low-maintenance label dispensing. RHR5 is well-matched for weigh-price applications in grocery departments and has the necessary approvals for indirect food contact.

RH6

RP45 & RP45 LW

Wash-off and recirculation for multi-use containers

RP45 and RP45 LW cover numerous rotational applications for plastic and metal crates, boxes, pallets, kegs and other multi-use containers. These adhesives last reliably for the lifecycle of the label and wash off quickly and cleanly for trouble-free container rotation

RP45 is intended for retail as well as standard logistics applications such as plastic transport boxes with smooth surfaces and metal kegs used by breweries. RP45 LW provides greater endurance on challenging rough and patterned surfaces and also in chilled warehouses and deep freeze conditions.

Optimal wash-off is achieved with hot alkaline water, though RP45 is also washable with pure hot water.

ULTRA-REMOVABLE ADHESIVES

RR522U, RR523U & RR524U

UPM Raflatac’s ultra-removable adhesives offer decisive removability where cleanliness really shows and where damage-free surfaces are essential to an item’s value. Clean removal also assists fast and cost-efficient handling.

These adhesives consist of minute adhesive spheres in an adhesive emulsion. This produces uniform, noncontinuous adhesive contact with the labelled surface, resulting in low-tack adhesion and a smooth peel-away.

The RR522U, RR523U and RR524U adhesives offer varying levels of tack for labelling in a wide range of logistics, general branding and retail promotion end uses, on surfaces from glass and white goods to books and newspapers.
