A Custom Envelope From Tension

With every envelope, you have options. Open end. Open side. Large. Small. Involvement devices. Special paper. Windows. Flexo. Litho… It is no short list, and there is no single solution. There are many ways to design an envelope.

But there is one constant with every envelope: It is a vehicle to meaningfully connect the sender to the recipient. For direct mail, it opens the door to an offer. For statement mailings, it’s a monthly appointment with your customer. For nonprofits, it is an opportunity to speak directly with donors.

Each envelope Tension manufactures has been precisely crafted to safely deliver its contents, allowing you to engage and interact with the recipient in a positive manner. During these interactions, you are subtly communicating your brand message and image. A quality envelope leaves a quality impression.

Tension Quality

Quality and reliability have long differentiated Tension’s products. Tension continuously looks for ways to improve its products, placing emphasis on developing repeatable and sustainable processes through Lean Sigma practices that build quality into every stage of the manufacturing process.

Lean Sigma serves as our foundation for leveraging best practices, minimizing waste and delivering continuous improvement on a daily basis. Tension includes quality control measures throughout the manufacturing process to ensure your envelopes perform at every stage of your mailing lifecycle. Some include:

  • Corporate-wide processes that are Lean Sigma driven and consistent from location to location.
  • Quality inspection processes prior to packing in cartons.
  • Vetted raw material suppliers, subject to regular reviews.
  • In-house, centralized training of envelope machine adjusters to drive up quality and drive down waste.

Tension’s national presence means you have the backing of a large, stable partner, yet with the local service our team brings from Tension’s numerous locations.

Award-Winning Printing and Design Work

Tension has been consistently recognized by the Flexographic Technical Association for expertise in envelope printing. Choose flexography, lithography or other printing methods for your custom-designed envelope. Whatever your preferences, an artist from the Tension Design Group can work with you to develop your unique envelope solution.
