Leading the Way

Tension Corporation is a leader in envelope, packaging and automation solutions, selling directly to businesses and organizations nationwide. Headquartered in Kansas City, Missouri, with sales and manufacturing facilities across the country and around the globe, Tension is a family-owned and -operated business that has been a market leader since it was founded in 1886. 

In 2011, Tension rebranded itself from Tension Envelope Corporation to Tension Corporation, reflecting its expanding presence in packaging and automation as well as its increasing footprint in international operations. Today, Tension’s three divisions are Envelope, Packaging & Automation, and International.

Tension's Innovative Approach

Tension has grown to become the second largest domestic envelope manufacturer. Known for its innovative envelope solutions, services and environmentally responsible options, it has been awarded more patents on products and processes than all of the other envelope manufacturers combined. Tension makes many of the envelopes you receive and handle daily, including direct mail envelopes, financial transaction envelopes, packaging envelopes and business communication products. Working with customers to deliver quality products, as well as to improve existing products and processes, is core to Tension’s culture.

An Expanding Customer Base and Global Reach

With its long history of adapting to the changing needs of its customers, Tension entered the automated packaging industry in the early 2000s. Tension Packaging & Automation serves customers in the internet order fulfillment business, and builds and equips mail order, central fill and specialty pharmacies. This division provides automation solutions, software, consumables and support services.

Tension International has operations in China and Taiwan. Tension Corporation began its overseas operations more than 15 years ago and continues to meet the needs of its regional customers today.

Tension is enjoying its fourth generation of family leadership and maintains active roles in its associated industries.
