Frequently Asked Questions
Are poly mailers truly waterproof in snowy or rainy shipping?
Poly mailers have a waterproof outer film that prevents moisture from soaking through the material. However, seams and the adhesive flap are potential weak points — for prolonged exposure or heavy slush it's smart to reinforce the flap with tape or use mailers with reinforced seals.
Do I need padded mailers for winter shipping?
If your item is fragile or has edges that could be damaged, padded/bubble mailers add impact protection while still offering water-resistant exteriors. For soft goods like clothing, standard poly mailers are usually sufficient if kept dry.
How can I prevent mailer seams or seals from failing in wet conditions?
Use a strong peel-and-seal mailer and consider adding a strip of tape over the flap for extra protection. Avoid overstuffing the mailer, keep address labels away from the seal, and choose mailers with reinforced or heat-sealed seams when possible.
