Crownhill Backloading Poly Packing List Envelope

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.
