30 products
Windowless envelopes feature a standard, solid design that does not permit viewing of contents until opened. They offer an additional level of security for important documents.
Self-Adhesive Windowless Envelopes
Self-adhesive windowless envelopes offer security with solid construction and an adhesive closure that eliminates the need to moisten flaps. The adhesive features a peel-away protective strip, and it provides a clean seal immediately upon contact. The strip protects the adhesive from dust and moisture for a longer shelf life.
