Standard Brown (Kraft) Reinforced Envelopes

These envelopes are constructed from laminated fiberglass strands between kraft paper layers which adds extra tensile strength and superior protection against grease, water, and oil damage.

The laminated fiberglass reinforcements protect the bags against tearing, puncturing, and abrasion. Being unpadded, these reinforced bags cost less to mail.

Secure enclosure for mailing items that don't require cushioning.
