WESTERN STATES #10-1/2 Health Insurance Claim Poly Window Envelope 4.5x9.5 24# Blue Wesco Tint Box of 500

Health Insurance Claim Envelope

These envelopes are sized at 4.5 by 9.5 inches and are designed for standard CMS Health Insurance Claim Forms. The poly window measures 1-1/8 by 4-3/4 inches and is positioned 3-7/8 inches from the left and 1-1/2 inches from the bottom. White sulphite paper with SFI certification and a vellum finish provides a professional appearance. A box contains 500 envelopes for high-volume office use.

Blue Wesco Tint Security

The Blue Wesco inside tint obscures printed claim data so sensitive patient information remains confidential during transit. White sulphite stock at 92% brightness ensures that form text and barcodes stay legible for scanning equipment. Self-sealing latex adhesive on the extended flap creates a secure closure without moisture. Side seam construction supports reliable feeding through inserter machines.

Standard Form Compatibility

Window placement follows the layout required for CMS claim forms so address and data fields align automatically. The 24-pound paper weight meets postal requirements for first-class mail without extra postage surcharges. Cartons of 2000 envelopes allow bulk storage for busy billing departments. Buyers who need a different window size or a non-tinted version should select another product.
