WESTERN STATES Open End King Size Catalog Envelopes 14x18 28# Tan Brown Kraft Center Seam Ungummed 100ct

Open End King Size Catalog Envelopes

These envelopes measure 14 by 18 inches and feature an open-end design with a center seam for reliable document insertion. Each unit uses 28-pound tan and brown kraft paper with a vellum finish and carries SFI certification. The ungummed flaps require separate sealing, and the box contains 100 envelopes suited for bulk mailing operations.

Sustained handling in mailroom workflows

The 28-pound kraft stock resists tearing when loaded with catalogs, reports or multiple sheets during continuous packing sessions. SFI-certified fibers maintain structural integrity through automated sorting equipment without excessive curling. Vellum surface texture supports consistent ink adhesion for addresses and postage marks across high-volume print runs. Ungummed flaps eliminate adhesive buildup on sealing machines during extended shifts.

Build quality and daily mounting implications

Center seam construction distributes stress evenly across the envelope body when filled to capacity. Roptex material provides a consistent feel that feeds cleanly through folder-inserter trays without misfeeds. Box weight of 9.8 pounds allows easy transport between workstations without specialized handling. Carton quantity of 500 supports palletised storage for operations that process thousands of pieces per week. Ungummed design means users must supply tape, glue or a moistener separately, adding a step to each sealing cycle.
