Open End Tyvek Catalog Envelopes

These envelopes are designed for high-volume mailing operations that require durable, lightweight protection for catalogs and large documents. The open-end format on the 15.5 inch side allows for easy insertion of bulky contents. A box contains 500 units suited for office mailrooms and fulfillment centers.

Moisture Resistant Bright White Construction

Spun bonded olefin material provides tear resistance and a moisture barrier that protects contents during transit. The 14 lb stock keeps shipping weight low while maintaining structural integrity. A smooth finish ensures reliable feeding through postage meters and sorting equipment.

Replaces Standard Paper Catalog Envelopes

The Tyvek construction upgrades from standard paper when tear resistance and weather protection are required for valuable printed materials. The green diamond border and printed "First Class Mail" marking meet postal identification needs. This product is not for buyers needing window envelopes or smaller letter-size formats.

Questions about this item

How do I seal the Kwik-Tak flap on these 12 x 15.5 Tyvek envelopes?

Peel the protective strip from the Kwik-Tak adhesive on the flap, press firmly along the entire 15.5-inch length, and ensure the green diamond border aligns for a secure bond.

Will the spun bonded olefin material degrade if stored in a humid warehouse?

The moisture-resistant Tyvek construction resists humidity damage; store boxes flat in a dry area to maintain the 14 lb paper integrity and adhesive performance.

At what weight does the 14 lb Tyvek seam risk splitting during shipping?

The 14 lb spun bonded olefin with center seam construction handles typical catalog loads; avoid exceeding carrier weight limits for the 12 x 15.5 size to prevent stress.
