Envelope manufacturing requires multiple adhesive technologies to perform reliably within one finished product. Front gum, back gum, remoistenable gum, latex gum, window patching, and seam adhesives each serve a different purpose and face different production demands. We understand the language of the envelope industry and the importance of machinability, lay-flat performance, clean application, and dependable closure. Whether you need an established product, a replacement technology, or help with a difficult application, we are prepared to listen and respond.
