Open-End Catalog Envelopes for High-Volume Mailing

These open-end catalog envelopes measure 9 by 12 inches and come in a box of 500. They suit offices, warehouses and fulfilment centres that send catalogues, reports or flat merchandise in bulk. The centre-seam construction and roptex material handle regular insertion without tearing. Buyers who need a window for address visibility or a peel-and-seal closure should look elsewhere.

20-lb Kraft Paper with Vellum Finish

The 20-lb suntan kraft stock is SFI certified and carries a vellum finish that resists smudging during handling. Remoistening seals activate with a quick dab of moisture, keeping contents secure in transit. Each box weighs 17 lbs, making it easy to calculate shipping costs for large mail-outs. No special storage climate is required beyond normal office conditions.

Fits Standard Trays and Shelving

Flat dimensions of 9 by 12 inches align with common mailroom trays, desktop organisers and postal sorting equipment. The centre seam leaves the full interior width usable for thick documents or padded items. A box of 500 reduces reorder frequency for high-volume shippers. Teams needing smaller quantities or different flap styles will need a separate SKU.

Questions about this item

How do I seal the remoistening flap on these 9 x 12 envelopes?

Moisten the gummed strip on the flap with a damp sponge or envelope moistener, then press firmly along the center seam to activate the adhesive.

When will I need to replace the box of 500 envelopes?

Replace the box once all 500 envelopes have been used; the 20 lb kraft paper is single-use and not designed for reuse after sealing.

What is the maximum weight these 20# envelopes can hold before the center seam splits?

The 20 lb paper weight supports typical catalog contents; exceeding several ounces per envelope risks tearing the center seam under sustained handling.
