UV-Curable Inks Provide Good Flowout
Akzo Nobel Inks
, Plymouth, MN; 612/559-5911;
UVOSCREEN II UV-curable screen inks for self-adhesive label substrates are formulated for use in all makes of rotary screen units as well as for fast-running, flatbed presses. Mfr. reports superior ink adhesion and color strength on a wide range of substrates, including PE, topcoated PP, and coated papers and boardstock. Inks are said to demonstrate excellent flow-out characteristics for solids with enhanced gloss yet retain the viscosity needed to hold fine type.

Adhesive Allows Secure Packaging with No Inner Bag
Henkel Group
, Düsseldorf, Germany; +49 (0)2 11-797-3533
Technomelt VS 715 adhesive is said to allow fine-grained products to be packaged in folding boxes with a sift- and insect-proof seal, without an inner bag. Technique requires applying many individual parallel lines of adhesive, which are subsequently squeezed to form a continuous, tight film. Co. reports that adhesive offers the following properties: high thermal stability; neat, tail-free cutoff at nozzles; good flow behavior; and long open time combined with rapid curing. Co. adds that adhesive won't loosen its bond strength even if package is coated on the inside with grease-repellent film.

Water-Based Foaming Adhesive Line Expands
E.T. Oakes Corp.
, Hauppauge, NY; 631/232-0002
A new series of Ad-Foam water-based adhesives is available in three price and production ranges. Adhesives feature foaming technology said to cut costs for users of water-based adhesives in litho, label, and other laminating applications by reducing adhesive usage and improving production efficiencies. Using precisely controlled, high-shear mixing technology, product reportedly creates a bond using 25%-40% less adhesive. Co. reports other benefits include improved layflat; minimal grain raise; reduced buildup on knives; faster setting speeds; and excellent holdout on recycled or highly absorbent substrates.

UV Flexo Inks Offer Detail and Gloss
Sericol Inc.
, Kansas City, KS; 913/573-3577
UVivid 800 is a series of UV flexo inks for narrow web printing applications. The entire range is engineered with the low viscosity of water-based inks and features ultra-high-density colors. Said to allow faster press speeds and provide finer detail and strong, consistent colors. Inks cure to a high-gloss finish that exhibits excellent mar and chemical resistance, co. reports.
