Q: Do you manufacture envelopes with outside seams?
A: Yes, we do manufacture envelopes with outside seams. Outside seams can make it easier to insert items since there are no flaps or seams on the inside of the envelope. No seams on the inside also reduces abrasion for products that are sensitive to scratching.

Q: What seal should I use on the envelope?
A: It all depends on what you are trying to achieve. The most common is the re-moistable seal, which is also the least cost. The most aggressive seal would be our peel & seal. If you are looking to reduce labor and are hand inserting a few items in an envelope, a latex seal works well. With latex, all you need is to fill the envelope and then close and press the flap.

Q: I have a large mailing, how can I save postage?
A: Having the right size envelope will save you postage. If you are just over the weight limit for the envelope class, a good way to save postage is to use envelopes made with Tyvek. Tyvek is stronger than paper and also lighter in weight. The Tyvek envelope will cost more but the savings in postage may provide you with your lowest total cost.
