National Adhesives Introduces VECTORPATCH Window Adhesives for Envelopes

National Adhesives, Bridgewater, N.J., published a flyer featuring new VECTORPATCH window adhesives, a window gum family that provides both machine speed and gum box stability necessary to work on all envelope folding machines.

Historically, envelope converters have had to compromise between the tack needed for high-speed machines and the gum box stability needed on slower equipment. Now, VECTORPATCH window gums solve this dilemma by delivering outstanding performance on a wide range of envelope folding machines—at a broad range of speeds and on a variety of papers. Specifically, VECTORPATCH adhesives provide high tack on the fastest folding equipment; gum box stability, resulting in minimal buildup on cutting knives and rollers over time; MERLIN compatibility, with the right properties to prevent window film warping; and outstanding adhesion to polystyrene.
