Conformer ® Mailers

Conformer Envelopes

For bulky, heavy items, normal paper mailers just won’t do. You need sturdy envelopes to keep items like books and magazines secure without bending. There’s nothing worse than hearing from your recipient that their magazine, special art print, or other item was damaged inside the mailer. We can make sure that doesn’t happen! Our collection of Conformer® envelopes features several mailers in different sizes to perfectly fit and secure your items inside. Our Conformer envelopes are designed to expand to create an ideal fit for your packaged items. They’re perfect for soft and hardcover books, as well as CDs, DVDs, clothing, magazines, calendars, prints, portfolios, contracts, and much more. If you’re concerned about the safety of your items, these mailers will alleviate your worries. The Peel & Stick closure seals the envelope tightly, and only opens when the tear spring is pulled off. We offer these useful envelopes in three styles—white, Kraft, and corrugate—in various paper weights. The Kraft mailers are high-quality and very durable, protecting your items from typical damages of postal transit. The corrugated envelopes are made out of high quality e-flute corrugate. The exterior is 33% post-consumer waste, and the interior is 100% post-consumer waste. If you keep sustainability in mind with your business, the corrugate mailers are the right choice for you! These expand up to 2”, whereas our others expand to 1”. The white paperboard envelopes are made for typical, everyday use. Choose the best Conformer envelopes for your needs in the following sizes: 7 ¼” x 10 ¼”, 7 3/8” x 9 5/8”, 9 ¼” x 12 ¼”, 9 ¾” x 12 ¼”, 9 ¾” x 12 ¾”, 11 ¾” x 14 ½”, and 12 ¼” x 14 ½”. These offerings are available in both booklet and open end styles. Either of them will be an excellent choice to keep your items safe until delivery. Not sure about which mailer to order?
