The FlowFly Mini Cooler is a flexible thermal barrier built for mid-range durations, typically keeping contents cool for 4 to 6 hours. Its material composition prioritizes impact resistance and flexibility, making it a functional choice for primary school students. The 600D polyester outer shell features a high-density weave that provides significant resistance to daily wear and tear.
Specifications show an insulation core of 5mm expanded polyethylene foam. This thickness offers a measurable increase in cooling efficiency compared to thinner economy bags. The internal liner uses heat-welded PEVA, which is non-toxic and allows for easy decontamination after spills. Because the seams are welded rather than stitched, they provide a helpful barrier against liquid leaking out of the bag.
The "Mini" designation is accurate to its size; the narrow profile is designed for compact storage but may limit the use of larger bento-style containers. To ensure the best performance, using flat-profile gel packs instead of loose ice cubes can prevent the bottom of the bag from sagging. The bag is also designed to collapse when empty, which is convenient for storage but means it provides minimal protection against crushing for soft food items inside.
Usage Guidelines
- Use slim gel packs to maximize the internal 5L volume for food containers.
- Wipe down the interior regularly to maintain a clean environment for food storage.
- Check the zipper radius periodically to ensure the teeth remain aligned for smooth operation.
If you prefer a style with a buckle handle for clipping onto other bags, the Mier Portable Mini Lunch Bag is a durable alternative.
