Common questions
How long does the adhesive stay effective if envelopes are stored?
The protective tear strip keeps the self-seal adhesive dust-free and protected, ensuring consistent performance throughout the entire case lifespan, even with extended storage.
Are these envelopes compliant with USPS and UPS shipping standards?
Yes. The 9 x 12" dimensions and 28 lb. kraft paper meet standard commercial mailing specifications for both USPS First-Class and UPS flat-rate shipping.
Do I need water or a moisture applicator to seal these envelopes?
No. Simply peel off the tear strip and press to seal instantly. This eliminates moisture application, speeds up processing, and eliminates humidity-related sealing failures.
What makes 28 lb. paper stock better than lighter alternatives?
28 lb. kraft paper provides puncture and tear resistance, protecting contents during transit and handling while maintaining cost efficiency compared to heavier envelope stocks.
