Frequently Asked Questions
Do insulated bubble mailers keep baked goods cold enough for multi-day shipping?
Insulated mailers slow temperature change but aren’t a standalone solution for long multi-day transit in warm conditions. For multi-day shipments add frozen gel packs, insulated liners or choose overnight/express shipping to maintain product quality.
Can I reuse insulated mailers?
You can reuse mailers if they remain structurally sound and the adhesive closure is intact, but many are single-use due to the peel-and-seal strip. Reuse is more practical for your own internal shipments than for sending to customers.
Which size should I pick for boxed chocolates or a cookie tin?
Measure the boxed item first and choose a mailer that allows a small cushion (about 0.5–1 inch) around the item for packing material. For boxed chocolates a mid-size 8 x 11 or 10 x 11 often works; for tins or trays consider 11 x 15 or 12 x 17.
