Custom Printed Conformer Expansion Envelopes: Expanding Your Possibilities

Our custom printed expanding envelopes are available in a variety of dimensions, making them perfect for any size item from jumbo to small. Such items include portfolios, presentation folders, legal and letter size documents, and CD/DVD discs. Depending on your purpose, select a side-loading or top-loading envelope in order to provide a completely different experience upon opening. Items are sealed inside the enclosure with tuck tabs or adhesive strips, which are determined by the style you choose.

Customization options are nearly unlimited with more than 60 paper stocks available with four imprint methods—four color process, PMS printing, embossing/debossing, or foil stamping. Surprise recipients with a splash of color inside the envelope by printing on side two or impress them with a combination of foil stamping and embossing for a classy appearance. For extra protection, select one of nine coatings offered.

Creative Envelope Customization

  • Print on side two to surprise recipients with a pop of color inside your envelope.
  • Use a lamination coating for extra durability and protection.
  • An eco-friendly brown Kraft paper stock can hide marks from postal machines and show your commitment to the environment.
  • Don’t limit your design to the front of the envelope. Use the back cover to expand design possibilities.
