Not every document that travels with a shipment fits neatly into a single category. That's where our Miscellaneous Documents Envelopes come in. From airbills and MSDS/SDS safety data sheets to hazardous material documentation, these envelopes cover the specialized paperwork that falls outside the broader categories of packing lists or invoices. Like our other pressure sensitive document envelopes, they adhere directly to the outside of any carton and are constructed with 2 mil poly, protecting enclosed documents from moisture and handling through transit.
