The BSC PREFERRED TYF1015WH is a case of 100 Tyvek self-seal envelopes built for applications that demand puncture, tear, and moisture resistance beyond what standard paper envelopes can deliver. Constructed from 14 lb. olefin material, these envelopes are rated at ten times the strength of comparable paper envelopes. The self-seal closure eliminates the need for separate adhesive or moisture activation, speeding up processing in high-volume shipping and mailroom environments. Available in plain or First Class printed border styles, they suit both internal distribution and outbound customer-facing mailings.
These envelopes are suited for shipping, receiving, and mailroom operations in commercial and light industrial settings. They are a practical choice for facilities teams, office managers, and supply room coordinators handling documents, parts lists, invoices, or other materials that require protection against rough handling, humidity, or transit damage. Each case contains 100 envelopes, allowing straightforward inventory management by the case unit.
Designed as a general-purpose Tyvek mailer envelope suitable for standard mailroom and shipping applications. Listed as equivalent to part number S-5154.
No tools or trade licensing are required for use. Store cases in a dry environment away from direct moisture before use. Activate the self-seal strip by pressing firmly along the full length of the flap to ensure a secure closure before sending.
