Common questions
Will these mailers work for items longer than 45 inches?
No, the 45" length is the maximum for this mailer. For longer items, consider our extended-length poly mailer options or alternative protective packaging. Oversizing will compromise the self-seal closure effectiveness and increase shipping costs.
How strong is the self-seal adhesive strip?
The pressure-sensitive adhesive provides a secure, tamper-evident closure that withstands standard shipping conditions and handling. Simply peel back the strip liner and press firmly for 2-3 seconds. The seal maintains integrity through sorting, scanning, and multi-carrier transit.
Can I write on these mailers with a marker or label?
Yes, the white polyethylene surface accepts markers, ballpoint pens, and thermal printer labels. We recommend testing ink adhesion and drying time with your specific marking method before full production runs.
Are these mailers weather-resistant for outdoor storage or delivery?
These mailers are moisture-resistant and protect contents from light rain and humidity exposure. However, they are not waterproof and should not be stored in standing water or extreme weather. For extended outdoor exposure, consider adding additional protective wrapping.
