Koehler Paper Introduces Sustainable Blue4est® Pro Label

Koehler Paper Expands Sustainable Blue4est® Thermal Paper Range: In addition to the sustainable Blue4est® POS till receipt, the Blue4est® Pro paper is now available for labels.

The new product Blue4est® Pro of the Thermal Paper division is a paper-based label material that is also known as facestock. It is being used for the new generation of environmentally friendly labels because it is produced without chemical developers. This means that it can be disposed of as wastepaper and is also approved for direct contact with food. As with the Blue4est® POS till receipt, the Blue4est® Pro self-adhesive label can be instantly recognized by consumers as environmentally friendly by its blue color.

World’s unique thermal adhesive material without chemical developers
The partnership between Koehler Paper and HERMA has given rise to the world’s first, and as yet only, thermal adhesive material without chemical developers. This is yet another example of outstanding development work by the Koehler Innovation & Technology division of the Koehler Group at the headquarters in Oberkirch, Germany. It is some years ago now that Koehler Paper, the world market leader in the field of thermal paper, first invested in the development of an environmentally friendly alternative to conventional thermal paper: the bluish Blue4est® POS till receipt paper. “We are pleased to now be expanding our environmentally friendly Blue4est® product portfolio with Blue4est® Pro for self-adhesive labels. This brings us one step closer to our vision of a “Blue Market,” a supermarket that only uses environmentally friendly blue till receipts and labels,” says Sebastian Früh, Deputy Director Thermal Paper Division at Koehler Paper. The labels can initially be used for fruit and vegetable scales. Further applications will follow soon.

Blue4est® Pro has additional protective layer
Blue4est® Pro is based on the same Blue4est® principle as the blue till receipt from Koehler Paper. With Blue4est®, the text is not produced through a chemical reaction to heat but instead it uses a purely physical reaction. An opaque functional layer on the paper becomes transparent when subjected to heat, which results in the black layer below becoming visible. Moreover, Blue4est® Pro features an additional layer that protects the paper from mechanical damage for use as a self-adhesive label.

ANDRITZ successfully starts up leading technologies for Klabin’s Eukaliner brown pulp mill in Brazil

ANDRITZ has successfully started up state-of-the-art and environmentally leading pulp production and chemical recovery technologies for Klabin’s Puma II line in Ortigueira, Paraná, Brazil. The ANDRITZ scope of supply included: *A wood processing plant with debarking and chipping line, which can process both eucalyptus (350 m3 sob/h) and pine (400 m3 sob/h), meaning that a log truckload of wood is emptied onto the line every ten minutes. *The HERBTM recovery boiler from ANDRITZ, which has a capacity of 3,300 tds/d with high steam parameters of 103 bar(a) and 502°C to maximize power generation. It is equipped with the autonomous Smart sootblowing control solution that combines Smart sensors (HEWI) and controls to ensure the cleanability period, a higher availability of the boiler, as well as greater operating safety. *A power boiler based on ANDRITZ EcoFluid bubbling fluidized bed (BFB) technology with a steam production capacity of 220 t/h. It is combined with the recovery boiler to form a “boiler island”, and some of the auxiliary equipment is shared between the two boilers. This provides savings in investment and operating costs. *A complete white liquor plant consisting of a recausticizing plant (5,000 m3/d) and an ANDRITZ LimeKiln (450 t/d) with a multi-fuel burner.

UPM seeks efficiency improvement in UPM Raflatac and in global functions

As a result of the weakening world economic outlook as well as the COVID-19 related restrictive measures and their consequences, the uncertainty in UPM’s market environment continues. To ensure future competitiveness, UPM keeps taking action to decrease fixed and variable costs in its businesses and functions. UPM’s label materials business UPM Raflatac plans to simplify its organisation and increase efficiency in operations and distribution. If implemented, the plans would reduce approximately 100 positions in UPM Raflatac’s global organisation, mainly in Europe. In addition, UPM aims to increase efficiency of its global functions by reorganising and streamlining the functions’ operations in five countries. If implemented, the plans would decrease the number of positions in the functions by up to 70, mostly in Finland and in Germany.

Lollicup® USA, Inc. Brings Manufacturing Back to the U.S.

In 2017, Lollicup's Reifenhauser extruder, which produces plastic sheets from resin, became completely operational. By adding this machine, they were able to cut energy use by about 20 percent and improve production by 40 percent, allowing more products to be produced domestically. "The extruder is capable of making thicker, higher quality sheets of plastic," said Production Supervisor Ron Gonzales. "These sheets are used to form Karat® cups and lids." 2017 also saw the initial phases of a new manufacturing plant in Rockwall, Texas. The manufacturing plant is projected to be operational in 2018 and will allow Lollicup to produce more products, in addition to adding products to their Karat and Karat Earth™ lines.
