These envelopes are well suited to e-commerce fulfillment, legal and administrative mail rooms, publishing distribution, and any operation regularly shipping flat materials that cannot be folded or rolled.

Constructed from 14 lb spunbonded olefin, these envelopes outperform standard paper and poly alternatives in strength-to-weight ratio, holding up through automated mail handling and multi-leg transit. White finish accepts direct labeling or label application cleanly. Each case contains 100 envelopes and ships via parcel carrier.
