Bsc Preferred TYF1823WS Tyvek Envelopes 100 Per Case

Product Description

The BSC PREFERRED TYF1823WS is a case of 100 Tyvek envelopes built for demanding shipping and mailing applications. Each envelope is constructed from 14 lb. olefin, the same high-density polyethylene material used in DuPont Tyvek sheeting, delivering puncture, tear, and moisture resistance that significantly outperforms standard paper envelopes. A self-seal closure strips the need for water activation or additional tape, speeding up high-volume mailing operations. Available in plain and First Class printed border styles, these envelopes suit a range of professional mailing needs. Each case contains 100 envelopes and is sold as a single case unit.

These envelopes are suited for shipping operations, office mailrooms, and distribution centers where document integrity and envelope durability matter. The moisture-resistant olefin construction makes them a dependable choice when contents must arrive dry and undamaged regardless of handling conditions. The self-seal strip supports efficient processing in high-throughput mailing environments. Both plain and First Class border variants are available within the TYF1823WS product line, making them appropriate for internal document routing or outbound customer correspondence requiring a professional appearance.
