Common questions
Are these envelopes suitable for USPS and shipping compliance?
Yes. The heavy gummed flaps provide secure, tamper-evident seals that meet USPS standards for first-class and bulk mail. The 28 lb. kraft stock is durable enough for standard shipping without additional reinforcement.
What makes the heavy gumming different from standard gummed envelopes?
Heavy gumming provides a stronger, more reliable seal with better adhesion, reducing the risk of envelope failures during handling, sorting, and transport. This eliminates the need for supplementary tape and ensures professional presentation.
Can I see through kraft envelopes?
No. The opaque 28 lb. kraft paper stock prevents contents from being viewed, protecting sensitive documents like invoices, medical records, and financial statements during transit and storage.
How many envelopes come in a case, and what's the per-unit cost advantage?
Each case contains 2,500 envelopes, making this a bulk-efficient solution that significantly reduces per-unit costs compared to smaller quantities, ideal for high-volume mailroom operations and corporate communications.
