What Tension does

Tension Corporation, doing business as Tension Envelope & Print, is a privately held custom envelope manufacturer and printed products company founded in 1886 and headquartered in Kansas City, Missouri. The company designs and manufactures a comprehensive portfolio of envelope products (business envelopes, direct mail envelopes, specialty envelopes, protective packaging mailers, Tyvek envelopes, and non-mailable specialty formats) and printed products (buck slips, self-mailers, continuous forms, presentation folders, labels, booklets, and peel-and-reveal mailpieces), supported by finishing capabilities including metallic inks, embossing, foil, and metallic paper. Its technology platform centers on integrated manufacturing and printing operations with proprietary interactive direct mail features such as Hot Note®, Sim-Pull®, Rip-Ope tear strips, Zip-Strip, Reveal, Trailing Edge, and Bangtail envelope designs, all offered with customization across materials, finishes, and inks.

Tension operates sales and manufacturing locations across the United States with additional manufacturing operations in China and Taiwan, making it one of the only US envelope manufacturers with international production reach. Its go-to-market is sales-led, with direct B2B sales via phone (1-800-388-5122), an enterprise sales team, a customer login portal, and quote-based pricing carrying a 25,000-unit minimum order quantity and multi-year contracts. The company serves a horizontal B2B customer base spanning financial services, healthcare, retail, and professional services for use cases including transactional billing, statement mailings, direct mail marketing, and promotional packaging. Revenue is generated primarily through one-time product sales supplemented by professional services (Tension Design Group, Tension Direct on-demand printing, Customer Inventory Management) and a sub-brand, Tension Packaging & Automation, focused on protective packaging and industrial automation solutions. The company maintains a strategic alignment with the US Postal Service, including annual participation in the National Postal Forum and participation in USPS promotional programs.
