What are paper mailing bags?

Durable kraft paper post bags designed for courier networks. They arrive flat, pack fast and protect soft or boxed goods with a neat, brandable surface. Most feature a peel & seal strip and optional second strip for easy returns.

Why choose paper over poly?

Recyclable & plastic-free: easy end-of-life in kerbside paper streams.

Premium look: kraft finish pairs well with tissue, cards and apparel.

Operational ease: fast sealing, stack neatly, simple SKU management.

Best-use scenarios

Apparel & soft goods: tees, knitwear, textiles—bag the garment, add a documents wallet and label.

Books & media: use with book wraps or board envelopes for corner protection.

Beauty & gifts: tissue-wrapped items, small cartons—smart unboxing without plastic.

Returns-friendly brands: choose dual-seal bags to simplify customer returns.
