UPM extends barrier technology into food labels

UPM has extended barrier paper technology into grease-resistant label stocks. The new grade targets food-contact applications without intentionally added PFAS.


IN Brief:

  • UPM Asendo 80 brings grease-resistant barrier technology into an 80gsm label face paper.
  • The grade supports UV flexo and UV inkjet printing, with UPM stating compliance with FDA and German BfR food-contact requirements.
  • The launch follows EU PFAS restrictions for food-contact packaging that became applicable on 12 August.

UPM Specialty Materials has extended its barrier-paper technology into label face papers with UPM Asendo 80, an 80gsm grease-resistant grade aimed at food-contact and other applications where labels are exposed to oils or fatty products. The launch moves a functional barrier already used in packaging papers into pressure-sensitive label constructions, where surface appearance, print performance and resistance to grease have to survive converting as well as end use.

UPM says no PFAS are intentionally added to the grade and that its papers are tested by independent laboratories. Asendo 80 is compatible with a range of adhesive types, supports UV flexographic and UV inkjet printing, and is available with FSC or PEFC certification. The company also states that the paper meets US Food and Drug Administration and German BfR requirements for food-contact use.

The timing follows the application from 12 August of PFAS restrictions in food-contact packaging under the EU Packaging and Packaging Waste Regulation. Those limits increase pressure on suppliers to reproduce grease and oil resistance without relying on fluorinated chemistry, while still providing customers with documentation covering the finished material’s intended use. Labels are part of that problem because the face stock can be exposed directly to oils, fats or condensation even when the label itself is not the main structural pack.

Grease penetration can change a paper label’s appearance, stiffness and print quality, leaving visible staining or weakening the surface during storage and handling. Resistance therefore has to work alongside adhesive performance, die-cutting, dispensing and application. A barrier face paper that performs in a laboratory but curls, tears or releases poorly on a labelling line would simply move the failure to another part of the packaging process.

Asendo 80 extends technology from UPM’s wider Asendo packaging-paper range, which is used in bags, wraps, pouches and other converted formats. The existing papers are designed around moisture and grease resistance for food and other packaging uses. Transferring that approach to a face stock gives label converters a paper option where the barrier function is built into the substrate rather than added through a separate fluorinated treatment.

The development sits within a broader reformulation cycle across fibre-based food packaging. Lecta moved its food-packaging portfolio to a no-PFAS-added standard earlier this year, covering papers, labels, bags and barrier grades as suppliers prepared for the August restrictions. The same regulatory pressure is now reaching secondary components that previously attracted less attention than trays, wraps or primary barriers.

Material substitution remains a system-level exercise. Adhesives, release liners, inks, coatings and curing conditions all influence the performance of a pressure-sensitive label, and food-contact compliance depends on the construction and intended use rather than a paper grade in isolation. A converter moving to Asendo 80 will still need to confirm that the finished label works with its adhesive system, print process and application conditions.

The printing specification is relevant because grease-resistant papers can behave differently under ink and varnish than conventional face stocks. Surface energy, absorption and drying affect dot gain, colour consistency and rub resistance, particularly on high-speed flexographic and digital presses. UPM’s support for both UV flexo and UV inkjet widens the production routes available, but customer trials will determine how the grade behaves across individual presses and ink sets.

Paper labels are also being pulled into wider recyclability assessments. A fibre face stock can fit a paper-led design strategy, yet the label’s overall effect still depends on adhesive, liner and the material of the main pack. PPWR is pushing packaging teams to look beyond headline substrate choices and towards complete structures, including small components that can interfere with separation, de-inking or material recovery.

That makes documentation almost as important as physical performance. Food and beverage companies increasingly ask suppliers for evidence covering substances of concern, food-contact suitability, fibre sourcing and recyclability alongside familiar specifications for print quality and line reliability. UPM’s independent testing and certification options give converters a starting point for those files, although the finished label still has to be validated for the actual application.

The launch addresses a narrow but practical packaging requirement created by the intersection of regulation and production performance. Grease resistance remains necessary even as PFAS use is restricted, and labels still have to run through established converting and application equipment at commercial speed. Asendo 80 offers one paper-based route, with adoption likely to depend on whether converters can reproduce its claimed barrier performance without sacrificing print, adhesion or dispensing consistency.

The next evidence will come from customer trials and commercial label constructions rather than from the base-paper specification alone. If the grade performs across common adhesives, print systems and food-packaging conditions, UPM will have extended its barrier technology into a component that is small in material terms but increasingly visible in regulatory and recyclability assessments.
