What are Tyvek Envelopes?  

Tyvek envelopes are tough, lightweight envelopes made with tear and moisture resistant material, offering security and protection for your most sensitive communications. 

Tyvek Envelope Sizes 

Because Tyvek envelopes are most often used to mail large, heavy documents, they often come in large and extra-large open end and open side envelope sizes, such as 6×9, 9×12 and 10×13.   

Tension specializes in custom envelope sizes for our entire product line. Tyvek envelopes from Tension are no different; they’re available in any size to fit your project needs.
