Kraft-Paper vs Poly Bubble Mailers: Which Should You Choose?

Kraft or poly outer? Which bubble mailer material suits your needs best.

3 min readUpdated April 2025

Key differences

Kraft outer: paper exterior. Natural look, printable, but not waterproof.
Poly outer: plastic film exterior. Waterproof, lightweight, tear-resistant.

Quick answer

Kraft for professional appearance and printability. Poly for waterproofing and lowest weight. Neither outer type is fully kerbside recyclable when combined with bubble lining. For maximum sustainability, choose paper-based alternatives with honeycomb padding instead. If sticking with bubble-lined, kraft looks more professional and accepts custom printing better.
