When buying plastic envelopes for you or your business you have to entertain several options or features before deciding on the specific product for your use. First, decide what it is that you will be primarily inserting into the envelope. Does it have to be completely sealed or are you sending it throughout the department? Second, depending on what is being sent determines the size of the envelope. For example, sending 8 1/2" x 11" standard memos from one department to another would preclude that you would like a 9" x 12" envelope. If the information is to be private then you would probably want it to be white or colored and possibly have a temporary sealing feature. Lastly, how often do you use these envelopes? This will determine if you'd like to buy a dozen or 100 at a time. Then you can easily shop by price and quantity for your specific product .
