Frequently Asked Questions
What prevents bending best: rigid mailers or semi-rigid protectors inside bubble mailers?
Semi-rigid plastic protectors inside a padded bubble mailer are a lightweight, postage-friendly way to prevent bending for cards. For larger prints, rigid cardboard mailers distribute pressure better and are preferable.
Are poly bubble mailers waterproof?
Poly bubble mailers are water-resistant and protect against rain and spills, but seams or labels can allow moisture in. For critical protection, add a sealed plastic sleeve or internal waterproofing.
How can I reduce postage without sacrificing protection?
Use the lightest mailer that still protects the item: semi-rigid protectors for cards, thin bubble padding for small items, and stiff cardboard for larger prints. Avoid oversized packaging and use flat mailers rather than boxes when possible.
