Common questions
Do Redi-Seal envelopes require moisture to seal?
No. Unlike traditional envelopes, Redi-Seal envelopes use pressure-activated adhesive. Simply fold down the flap and press firmly, no water, sponge, or saliva needed. This speeds up mail preparation and reduces employee fatigue in high-volume mailrooms.
Are these envelopes suitable for standard business mail and shipping?
Yes. At 9 1/2" x 6 1/2", these envelopes meet USPS and carrier standards for first-class mail and flats. The 28 lb. paper stock provides durability for transit while maintaining cost-efficiency for bulk mailings.
How many envelopes are in each case?
Each case contains 1,000 individual envelopes. This bulk quantity is ideal for businesses with consistent mailing volumes and allows for cost-effective inventory management.
Can Redi-Seal envelopes be used with mail sorting machines?
Yes. The Redi-Seal closure is designed to be compatible with standard commercial mail processing equipment, making them suitable for automated mailroom workflows and third-party fulfillment centers.
