Not for: People shipping thick, bulky or fragile items, which need bubble padding or a box.
What the AI looks for in Envelope Mailers
- Rigidity versus padding
- Choose rigid board for flat items that must not bend, bubble lining for small hard objects and poly for clothing. Matching the mailer type to the item prevents most damage.
- Flat versus package rate
- In US mail, only flexible envelopes no more than 3/4 inch thick qualify as flats; rigid mailers are priced as packages. The choice affects postage cost.
- Seal
- Choose a peel-and-seal strip with full-width adhesive. Gaps in the seal let contents slip out.
Brands that matter
- Jiffy: Rigid and padded mailer lines.
- Scotch: Consumer-friendly bubble and poly mailers.
What to avoid
- Poly mailers used for hard or fragile items.
- Paper-padded mailers that shed fibre around contents that must stay clean.
