Self Seal Diploma Mailers — Our dipoma mailers are made from durable .28 heavy gauge paperboard. Let us imprint your school logo and return address for a professional looking envelope.

These easy to seal "tamper-resistant" diploma mailers, also known as self seal mailers, or tape and seal mailers, are great! Once these self seal mailers are sealed, any tampering is very evident. Yet, this mailer can be easily opened by simply pulling the tear tab on either side of the flap. The self seal feature has been a long standing favorite with our customers because of its ease of use. If your requirements are ease of use, and tamper resistance, our self seal mailers are exactly what you are looking for.

Manufactured from recycled material with a semi-gloss white surface, our self seal mailers are ideal for offset imprinting,

All of our diploma mailers ad made of .028 clay coated news back.

Offset imprinting, letterpress imprinting, and full color offset printing are available on all of our mailers. Need a special quotation for a special envelope, please call us.
