Temp Shield Insulated Bubble Mailer Bags – 240×330mm | Cold Chain Grade | Australia
The Dry Chill Temp Shield 240×330mm Insulated Bubble Mailer is the benchmark foil insulated bag for Australian e-commerce and last-mile cold chain operations. Designed for fresh food delivery, pharmaceutical courier packs, meal kit components, and temperature-sensitive retail — this mailer combines multi-layer MPET foil insulation with a bubble-back inner layer to deliver genuine cold chain performance in a mailing format.
MPET Foil vs. Standard Aluminium Foil — Understanding the Difference
Not all foil insulated mailers perform equally. The Temp Shield range uses metallised polyethylene terephthalate (MPET) film — not the standard aluminium foil laminate used in entry-level cold chain mailers. MPET reflects up to 97% of radiant heat versus approximately 85% for standard foil laminates. In an Australian summer context — where a courier bag can be exposed to radiant solar heat in addition to high ambient temperatures — this difference in radiant heat rejection translates directly to longer product hold times and fewer temperature excursions.
The bubble backing provides an air-cell insulation layer that slows conductive heat transfer into the package. The combination of high-performance radiant barrier (MPET) and conductive insulation (bubble) makes the Temp Shield bag suitable for Australian summer conditions that routinely exceed the specifications of imported European cold chain mailer products.
Suitable Applications
- Fresh meat, seafood, poultry, and dairy last-mile delivery
- Pharmaceutical courier packs (clinical samples, pathology specimens, temperature-sensitive medications)
- Nutraceutical and supplement cold chain (probiotics, biologics)
- Cosmetics and beauty product cold chain
- Florist and fresh flower delivery
- Chocolate, confectionery, and specialty food gifting
Recommended Pack-Out
For 4-hour metro deliveries in Australian summer conditions: one 250g Dry Chill 2000 gel pack frozen to -18°C per mailer is typically sufficient. For 8-hour or overnight transits: two 500g gel packs. For 24-hour interstate transits: two 1kg gel packs. These are indicative recommendations — contact our team for validated pack-out specifications for your specific product, transit profile, and worst-case ambient.
