❓ Frequently Asked Questions (FAQ)
1. How long does it keep food hot/cold?
It retains warmth for approximately 3-4 hours and cold for 4-5 hours under normal room temperature (20-25°C). For best results, pre-heat or pre-cool the bag with a hot/cold pack.
2. Is the Insulated Thermal Bag leak-proof?
The aluminum foil inner layer is sealed at seams, but it’s leak-resistant (not fully submersible). It handles minor spills well; avoid carrying open liquids without a tight container.
3. Can I microwave the bag?
No. The aluminum foil interior reflects microwaves and will cause sparks. Always remove food from the bag before reheating.
4. Is the material safe for direct food contact?
Yes. The aluminum foil layer is food-grade, non-toxic, and odor-free. However, we recommend placing food in enclosed containers to prevent spills and maintain hygiene.
5. How do I clean it?
Wipe the interior and exterior with a damp cloth and mild detergent. Air dry fully before folding. Do not immerse in water or machine wash.
6. Can I customize it with my logo?
Absolutely. We offer custom printing (screen or heat transfer) on the PET outer layer for bulk orders. Contact us for MOQ and pricing.
7. Does it fold flat?
Yes. The EPE foam is flexible, so the bag collapses completely flat – ideal for storing in a drawer, backpack, or glove compartment.
8. What sizes are available?
We offer Small (lunchbox size), Medium (grocery bag), and Large (family picnic). Custom dimensions available upon request.
