Frequently Asked Questions
How do box mailers reduce dimensional weight costs?
By using a snug, low-profile package that fits the item closely, you reduce the package's cubic volume — the key driver of dimensional weight. Choosing lightweight corrugated or padded mailers instead of oversized boxes minimizes the billed size while still protecting the product.
When should I use a padded mailer vs a corrugated box mailer?
Use padded kraft bubble mailers for flexible, non-breakable items (clothing, soft goods, small electronics with their own boxes). Opt for corrugated or double-wall fold mailers for fragile or rigid items that need crush resistance (ceramics, glass, tumblers, small framed prints).
Can I use tuck-tab mailers without extra tape?
Many fold-to-form mailers are designed with interlocking tabs for basic closure and fast packing. For heavier items or long transit, adding a bit of tape increases security. Inspect tab stability on a small sample before committing to tape-free shipping at scale.
