Common questions
Can these envelopes be reused multiple times?
Yes. The reinforced metal clasps are designed for repeated opening and closing, making these envelopes ideal for operations requiring multiple use cycles. This reusability significantly reduces packaging costs per transaction over time.
What is the weight capacity for these envelopes?
The 28 lb. woven paper construction provides excellent durability for standard business documents, invoices, and lightweight parts. For heavier items, we recommend verifying contents weight does not exceed 2-3 pounds to ensure secure clasp retention.
Are these envelopes compliant with USPS and shipping carrier standards?
Yes. The 9 x 12" dimensions fall within standard mailing specifications for USPS, UPS, and FedEx. The gummed flap provides a permanent seal suitable for tracked and certified mailings.
How should I store bulk quantities of these envelopes?
Store in a cool, dry environment with humidity levels between 40-60% to preserve the gummed flap's effectiveness. Cases stack efficiently on standard warehouse shelving and pallets for easy inventory management.
