WESTERN STATES Open End Catalog Envelopes 10x13 28# Green Diamond Border Pressure Seal Box 500

Open End Catalog Envelopes

These 10 x 13 inch open end catalog envelopes ship in a box of 500 and are printed with a green diamond border plus "First Class Mail" on the face. The pressure sensitive seal removes the need for moisture and works well for high volume mailroom operations. Buyers who need a windowed envelope or a different flap style will need another product.

Sustained mailroom performance

The 28 lb Suntan Kraft stock with vellum finish resists tearing during repeated handling and automated sorting. SFI certification confirms responsible fibre sourcing for organisations tracking supply chain standards. The centre seam construction distributes stress evenly when envelopes are stacked or fed continuously. Heavy inserts beyond the paper weight may cause seam failure.

Postal standard limits

First Class Mail markings meet USPS requirements for letters and flats up to 13 ounces, but the envelope itself does not guarantee acceptance of heavier contents. Non machinable surcharges apply if thickness or rigidity exceeds automation limits. International shipments require additional customs forms not supplied with the box. Users sending parcels over the weight limit must select a different mail class.
