About this item
SKU EN1010 — 9" × 12", 28 lb. Woven Paper, White. Sold as a case of 500, shipped from US warehouses.
Durable 9x12 " white clasp envelopes built from 28 lb. woven paper with reinforced metal clasps for repeated reuse, cutting your packaging costs per shipment. Sold by the case (500 units), these office envelopes feature a secure gummed flap for permanent sealing when needed.
Common questions
Are these envelopes reusable and how many times can they be reused?
Yes. The reinforced metal clasps are specifically designed for envelope reuse, and the durable 28 lb. woven paper withstands multiple open-close cycles. Most organizations report 5-10+ reuses per envelope depending on handling conditions and mail volume, significantly extending ROI versus single-use envelopes.
How do I seal these envelopes securely for shipping?
Simply moisten the gummed flap and press it closed for a permanent, tamper-evident seal. The gummed closure creates a secure bond without additional tape, adhesive, or equipment, and maintains compliance with standard shipping and document security requirements.
What is the weight capacity and what types of documents can these hold?
The 28 lb. woven paper construction and reinforced metal clasp design support standard office documents, contracts, invoices, and light small-part shipments. For exact weight limits specific to your application, contact our packaging specialists to ensure optimal product selection.
Can I purchase smaller quantities than a full case of 500?
This SKU is sold as a case of 500 units to maximize cost efficiency. For smaller order quantities or custom case breaks, please contact our sales team to discuss bulk pricing and packaging options tailored to your procurement needs.
