Envelope Adhesives Guide from National Adhesives
National Adhesives, Bridgewater, N.J., offers a free, eight-page brochure providing a summary of various types of adhesives and gums used in envelope manufacturing.
“Envelope Adhesives 101” contains information on the five most common adhesives used in envelope production, as well as specialty adhesives for applications such as X-ray film storage envelopes, archival envelopes and translucent-paper stocks.
Adhesive formulation data, a coating-weight chart for various paper stocks and a chart detailing adhesive characteristics—such as thickness, adhesion, humidity, resistance, tack and appearance—are provided. Featuring illustrations and photographs of various envelope types, the brochure also explains the best practices for handling and storing finished products.
In other news, National Adhesives introduced a high-performance, ultimate-control resin laminating adhesive for maximum line speeds that can reduce adhesive usage and production costs on point-of-purchase and other applications.
The 32-541A resin UC adhesive provides a balance of tack, open time and set speed, and reduces moisture transfer into the sheet. Superior hold-out properties enable operators to meter glue line width, reducing waste adhesive drip from flute tips. Glue line thickness can be metered down, and adhesion and set time can be controlled on an application-specific basis.
