Archroma has several new offerings

Reinach, Switzerland-based Archroma says that with a 1-million sq. ft. facility in Martin, SC, it is one of only a few specialty chemical and dye manufacturers in the US dedicated to serving the paper and textile industry. Recently, it introduced several new products to the NA market.

• Its disulfonated fluorescent whitening agent (FWA), Leucophor® ACK liquid, brings a new ecological focus to the field of FWA: It is ultraconcentrated, free of urea and other additives that increase nitrogen load and COD in back- and waste-waters. The higher actives content brings advantages of fewer deliveries, reduced freight costs, lower greenhouse gas emissions and better use of storage capacity. Leucophor ACK liquid enables brilliant whiteness in stock and coating applications, and complies with major international eco-labels, says Archroma.

New patented, urea-containing alternative, Leucophor ACS liquid, offers similar advantages.

• Archroma also offers a unique system combining: 1) Its Cartastrength® process chemicals to increase the stability of corrugated fiberboard and allow manufacturers to achieve high levels of dry strength with lower amounts of fresh fibers; and 2) the coatings from its Cartaseal® range including fluorine-free alternatives to wax water barriers that facilitate recycling by breaking down during repulping without needing further additives.

The latest addition to the range, Cartastrength HWM liq, provides high-performance wet strength, in particular to tissue paper, whilst coming in high solids form for low shipping and storage costs. Cartastrength HWM liq is FDA compliant and displays lower AOX (adsorbable organic halides) than typical Grade 1 products.

• Pitch and stickies are the result of natural resin residues and other adhesive material found in wood fibers and in address labels or self-sealing envelopes. Both can seriously compromise recycled papermaking by clogging up machinery and causing unwanted agglomerations and deposits. Archroma says its Cartaspers ® polymers can solve that problem in different ways.

The latest innovation in the range, Cartaspers PLH liquid, is a single-product breakthrough enabling easy and highly-effective control of pitch and stickies deposition especially in soft-water pulp and papermaking environments. The company says that pulp mill tests report easier application, better performance and cost savings compared to alternative deposit control systems.

Cartaspers replaces talc-based products, the liquid form solution offering both consistent quality and easier application than talc. The deposit control polymers reduce downtime, improve end-product quality and offer other economic and ecological advantages.

• Cartaguard® is an eco-advanced, high-performance oil and grease barrier for food packaging, says Archroma. When applied to products such as fast-food boxes and wrappers, pet-food packaging, molded pulp plates and boxes containing bouillon cubes, Cartaguard KST & KMP coatings provide a strong and long-lasting barrier against grease and water.

The series includes an additive that has been optimized for the production of molded pulp packaging and can be added to thick stock. These cationic fluoropolymers have been approved for food contact by both the American FDA and Germany’s Federal Institute for Risk Assessment (BfR).
