Common questions
Do these envelopes require moisture or water to seal?
No. Redi-Seal™ envelopes feature a pressure-activated adhesive strip. Simply fold down the flap and press firmly to seal, no moisture, licking, or additional equipment required. This saves time and eliminates seal failures from improper moisture application.
What makes 28 lb. paper stock better for shipping compliance?
The 28 lb. kraft paper provides tear and puncture resistance, meeting USPS and carrier standards for mailing. This weight ensures contents stay protected during sorting, handling, and transit, reducing damage claims and improving customer satisfaction.
How many envelopes are in each case?
Each case contains 1,000 envelopes, making bulk ordering cost-efficient for mailrooms and businesses with regular mailing needs. This quantity reduces per-unit costs and minimizes reordering frequency.
Are these envelopes suitable for sensitive or confidential documents?
Yes. The press-and-seal closure creates a secure, tamper-evident seal ideal for invoices, contracts, and confidential communications. The kraft paper provides a professional appearance while the durable construction protects document integrity.
