Frequently Asked Questions
Are these mailers recyclable or compostable?
Many of the cardboard options are curbside recyclable, but film coatings or glossy lamination can affect local recycling rules. Some poly mailers use additives or soy-based inks to reduce environmental impact, but plastic recyclability depends on your area's programs—check local recycling guidelines.
Which mailers are best for fragile items?
Corrugated, multi-layer boxes with higher edge crush ratings or double-wall construction provide the best protection for fragile items. Look for reinforced corners and a snug fit to reduce movement; add recyclable void fill where needed.
Can I use these for international shipping?
Yes—both sturdy corrugated boxes and thicker poly mailers can be used for international shipments, but verify carrier size/weight limits and add extra protection (padding, tamper-evident seals) for long transit. Also confirm materials meet destination-country recycling or disposal rules if sustainability is a concern.
