Common questions
Do Redi-Seal envelopes require water or moisture to seal?
No. Redi-Seal envelopes feature a pre-applied, pressure-activated adhesive strip. Simply fold down the flap and press firmly. The envelope seals instantly without any moisture, eliminating sponges, water dispensers, and mess.
Are these envelopes suitable for postal service mailing?
Yes. These 6 x 9" White Redi-Seal Envelopes meet USPS standards for standard mail and business correspondence. The durable 28 lb. paper stock withstands standard mail handling, sorting, and delivery processes.
How much can I save in mailroom labor with Redi-Seal technology?
Redi-Seal eliminates the time needed to apply moisture and manually seal each envelope. Studies show businesses can reduce mail prep time by 20-30% per piece, which adds up significantly with high-volume mailings. One case of 1,000 envelopes demonstrates immediate time and cost savings.
What makes 28 lb. paper stock better than lighter alternatives?
28 lb. paper stock provides durability and a more professional appearance than lighter envelopes. It resists tearing during handling, sorting, and delivery, reduces see-through from standard business documents, and conveys higher quality to recipients.
