Common questions
Will these envelopes stick to wet or damaged packages?
The adhesive is designed for clean, dry package surfaces. For optimal adhesion, apply to boxes before exposure to moisture. The 2 mil poly material protects documents inside from water damage, but application surface should be clean and dry.
Are these envelopes carrier-compliant for FedEx, UPS, and USPS?
Yes. The "Invoice Enclosed" pre-printed message and orange color meet all major carrier requirements for domestic and international shipments. These envelopes are commonly used by fulfillment centers shipping with FedEx, UPS, and USPS.
What's the cost advantage of buying 1,000 per case?
Bulk case pricing significantly reduces per-unit costs compared to smaller quantities, typically saving 30-40% versus retail packs. For shipping departments processing 50+ packages daily, a single case lasts 2-3 weeks, making it the most economical option.
Can these envelopes hold multiple pages or thick documents?
Yes. The 4 1/2" x 5 1/2" dimensions accommodate standard packing slips, invoices, and multi-page shipping documentation. The adhesive back securely holds contents without tearing, even with 5-10 page documents.
