Poly mailers vs paper mailers

Two mailing-bag routes — one prioritises water resistance and cost, the other recyclability and feel.

Quick answer

Choose poly mailers for waterproofing and the lowest postage; choose paper mailers for kerbside recyclability and a premium, plastic-free unboxing.

When to request a quote

Ask for a quote if you want branded or printed mailers, or a plastic-free switch across your range.

Frequently asked questions

Are paper mailers waterproof?
Not fully. Paper mailers resist light moisture but aren't waterproof like poly. For weather-exposed deliveries, poly mailers or a poly liner are safer.
