Crownhill Backloading Poly Packing List Envelope - 100 / Pack (CWH81145)

Poly packing list envelopes save time when protecting invoices, shipping labels, packing lists or other important documents while shipping. Simply load, peel and stick pressure-sensitive, waterproof poly envelopes to packages. Clear half windows make it easy to read addresses or other information. Tamper-evident, back-loading style offers maximum security, since once documents are loaded in the envelope, they cannot be removed without destroying the envelope. Poly packing list envelopes come in a handy dispenser box. They are not made for food products.
