Common questions
Can these envelopes be reused?
Yes. The ungummed flap design allows secure resealing with tape or adhesive, making these envelopes ideal for businesses seeking cost-effective, sustainable packaging solutions that reduce per-unit spending on repeat shipments.
Are 15 x 20" kraft envelopes compliant with USPS and major carriers?
These jumbo envelopes work well for oversized mail; however, verify carrier specifications for your specific shipment weight and destination, as some items may require Priority Mail or parcel services depending on total package dimensions and weight.
What weight documents and materials can these envelopes safely protect?
The 28 lb. kraft paper stock handles documents, catalogs, photographs, and moderate-weight printed materials effectively. For extremely heavy items, consider upgrading to reinforced mailers or boxes for optimal protection.
Why choose ungummed over self-seal envelopes?
Ungummed flaps reduce costs per unit, prevent accidental sealing, allow envelope reuse, and provide flexibility in sealing methods, making them more economical for high-volume mailroom operations and businesses with variable shipment requirements.
