Common questions
Will these mailers keep products cold without ice packs or gel?
These mailers provide passive thermal insulation via the aluminum foil barrier, which slows temperature transfer. For maximum temperature control during multi-day shipping, we recommend pairing with gel ice packs or phase-change materials. The barrier alone extends the thermal window but doesn't replace active cooling.
Are 24 x 20" Cool Barrier Mailers UPS and FedEx eligible?
Yes. At 20" x 24", these mailers fall within standard parcel carrier dimensional limits and are compliant with UPS, FedEx, and USPS Priority Mail eligibility. Lightweight construction helps you avoid dimensional weight surcharges on 2-3 day shipments.
How much shock protection does the 3/16" bubble lining provide?
The 3/16" bubble lining absorbs moderate impact and vibration, protecting contents from damage during handling, sorting, and transit. This thickness is ideal for fragile items like glass bottles, ceramics, and delicate electronics. For extremely fragile goods, consider layering with additional cushioning or bubble wrap.
Can I order smaller quantities than a case of 50?
