Bsc Preferred TYE12164WS Tyvek Envelopes 50 Per Case

Product Description

The BSC PREFERRED TYE12164WS is a case of 50 Tyvek envelopes constructed from 18 lb. olefin material. Tyvek construction delivers puncture, tear, and moisture resistance that significantly outperforms standard paper envelopes. Each envelope features an expandable gusset to accommodate bulky contents and a self-seal closure that eliminates the need for tape or additional fasteners. These envelopes are well suited for shipping documents, parts, and other items that require protection during transit. The case unit of measure means all 50 envelopes ship together as a single case quantity.

These Tyvek envelopes are used in shipping rooms, mail centers, and distribution environments where envelope durability is a priority. The self-seal design supports high-volume mailing workflows without requiring water-activated or pressure-sensitive tape. The expandable construction handles irregular or thick contents without tearing at the seams. Packaging and shipping operations in commercial, industrial, and office settings commonly stock these envelopes for outgoing mail and courier shipments.
