Common questions
What temperature range does the aluminum foil barrier maintain?
The aluminum foil exterior helps reduce heat transfer and maintain cooler internal temperatures during transit. Actual temperature performance depends on ambient conditions, mailer content, and ice pack usage. For critical temperature-controlled shipments, we recommend pairing with gel packs or dry ice.
Is the 3/16" bubble lining sufficient for fragile items?
Yes. The 3/16" bubble cushioning provides solid shock protection for fragile contents. The bubble design distributes impact across a wider surface area, reducing risk of breakage. For extremely delicate items, consider layering additional bubble wrap inside.
Can these mailers be used for UPS, FedEx, and USPS shipments?
Yes. Cool Barrier Bubble Mailers are carrier-agnostic and accepted by all major shipping carriers including USPS, UPS, and FedEx. Verify weight and dimension restrictions with your carrier for your specific service level.
Are these mailers water-resistant for moisture-sensitive products?
The aluminum foil exterior and sealed bubble lining provide excellent water-repellent protection, helping keep contents dry during transport and storage. However, for submersion risk scenarios, we recommend using additional waterproof liners inside the mailer.
