Frequently Asked Questions
Are these insulated mailers food-safe?
Most foil/bubble mailers are safe when used with a food barrier — wrap baked goods in parchment, sealed containers or liners before placing them inside to avoid direct contact with the metallic layer.
How long will an insulated mailer keep baked goods fresh in winter?
Insulated mailers help for short regional runs (up to 24–48 hours depending on external temps). For multi-day transit, include frozen gel packs or dry ice and choose thicker/larger mailers to maintain a cold chain.
Do I need extra packing materials inside the mailer?
Yes. Use cardboard inserts, bubble wrap, or food-safe trays to prevent crushing and maintain presentation; secure ice packs so they don't touch food directly and use absorbent pads to manage condensation.
