Ensure your temperature-sensitive products arrive fresh and secure with this reliable thermal shipping solution. Designed for short-term cold chain protection, these insulated mailers are ideal for shipping liquid yeast that require controlled conditions during transit.

Each mailer is constructed with a 3/16″ metallized bubble layer that provides both cushioning and thermal resistance, helping to maintain internal temperatures while guarding against impact and rough handling. The reflective metallic surface minimizes heat transfer, while the bubble insulation offers an added layer of protective padding.

Fully FDA compliant, these mailers meet food safety standards, making them suitable for direct contact with consumable products.

For best results, pair with cold packs to achieve up to 24 hours of economical, reliable shipping protection.
