Quick verdict: Self-seal poly bubble mailers are the best all-around choice for lightweight, non-fragile products because they add padding without the bulk of a box. Kraft bubble mailers are better when you want a more traditional paper exterior.
Bubble mailers balance protection, weight, and cost. The right size matters because oversized mailers waste space while undersized ones stress seams and closures.
